Physical Changes to the Astro 320 HandheldSee the Garmin Astro 320 COMBO, Garmin Multi-Dog Systems, Extra T5 Collars, and the Garmin Astro 320 "Handheld Only".
The Astro 320 features a body type based on the Garmin 62ST, where the original 220 was based on the Garmin 60. The 320 will be a similar size and shape for Astro users. It has a fully rubberized outer coating with an over molding, making it a little easier to grip. The non rubber exterior is trimmed in orange in place of green on the original, which is nice in a hunting environment. It's also going to stand out a little bit better if you set it down somewhere or drop it in the grass.
Along with the over molding is an improvement in the rubber around the RF antenna. One of the problems with the 220 was that changing antennas on a regular basis would tear the rubber around the antenna. This fixes that issue.
The power button on the 320 is located on the right side of the handheld. I like this change since it is a more convenient location. The power button on the original 220 is in between the GPS antenna and the radio frequency antenna. It's a clumsy, hard to reach position.
The keypad design on the 320 has the exact same button set up as the original 220, but the buttons are raised slightly higher and they're square instead or rounded. The overall keypad is a little bit bigger, especially the arrow keys. Several of the lower buttons are also larger. This should help make the unit a little easier to operate when you are wearing gloves.
One of my favorite changes is the new location of the lanyard attachment. On the Astro 220, the lanyard attachment is on the left side toward the top. No matter how you wear it, the handheld faces away from you. When you grab it, you have to turn the unit back in the right direction to see the screen. The 320 lanyard attachment location is at the bottom of the unit. You are able to strap in and hold the unit facing down on your body. This way I can just pick it up and look at it with out having to turn it. When I am finished, I can let go of it and it goes right back into position.
The Lanyard attachment is also much wider than the original. This will open up some options on new attachments that will make the unit easier to carry and more secure.
Along with the new lanyard changes, the battery cap on the back of the 320 features the Garmin "backbone" design. It's designed to work with certain Garmin accessories that snap onto it. This will also open up a bunch of new ways to carry your handheld.
Astro 320 Software Changes and Improvements
Older GPS products have what's called a 2-axis compass. For a 2 axis compass to work correctly you have to hold the handheld unit flat. If you're familiar with the Astro 220, the words "hold flat" will appear on the screen when you are tracking your dog and holding the unit at any angle. The 220 can't give you an accurate dog location unless it is held flat.
The 320 does not have this issue because it has what's called a 3-axis compass. It can handle all three dimensions. It doesn't matter which way you are holding the unit. You can hold it straight up and down and it's going to give you the correct direction of your dog. I find this to be really handy especially since I want to be able to grab my unit and get a dog location fast. With the 2 axis compass, you always have to give it a second or two to adjust when you move the unit. The 320 doesn't have that problem.
Having a 3 axis compass changes the way that you calibrate your hand held. The new process is very different from what we have been doing with the Astro 220, but the new model walks you through it. With the previous model, calibration was relatively simple. You just held the unit flat and turned it in a complete circle two to three time until it told you to stop.
To calibrate the Astro 320, you have to turn the unit in all three directions. When you start the process, the handheld tells you to slowly turn the unit in the direction shown. It then shows you an image and the direction to turn it. Once completed, it tells you the next direction. Once you have done steps one and two it shows you the third and lets you know when you are done. If at any point you do not move the unit correctly, it will stop you and tell you where to start again.
I've always recommended that people calibrate the Astro every time they use it. I'm not sure if we'll have to calibrate on the 320 as often, since the 3 axis compass will fix some of the issues. The biggest advantage is the handheld is going to be a little less finicky as far as how you have to hold it. That's going to be a great thing for everybody.
Dog Set Up
One of my favorite new things about the Garmin Astro 320 is the new Dog Set Menu. In the previous generation you would add the dog, it would automatically set the name based on how many dogs you already had in the system, and it would add it. It would not allow you to do anything else to it. You would then have to go into the Dog Info screen to change the dog's name, change the update rate, or to make the dog a pointing dog or treeing dog.
The Astro 320 goes about this process a couple of different ways. The first part is that when you add the dog, you are able to name the dog from the add a dog screen. So that's handy. You don't have to go to another screen. You just make the name change right there and you're done.
Universal Dog Settings
If you run pointing dogs, then typically you run all pointing dogs. If you run hounds or treeing dogs, you run treeing dogs. All of your dogs are typically going to be set up the same way. It's a waste of time to have to edit each and every dog when you add them.
The way the new system works is you make all the changes to your first dog and set him up the way you want him. You set his update rate and you set his dog type. When you add your next dog, the system will automatically apply the same setup that you put in on the first dog. This is a really nice time saver. It makes the settings universal, so there's no need for you to have edit each dog every time you add one to the 320 handheld.
The same thing is true on update rate. The majority of us are going to run this system on a five second update rate, and that's the automatic setting. But if you are one of the few that likes your update rate to be 10 seconds, or 30 seconds, or two minutes, once you make that change it will be applied universally every time you add a new dog to your handheld. All your dogs will be set to the longer update rate.
At the same time, if you DO want to change any of these settings for one specific dog, you can go into the dog info menu and edit each dog individually. Change him to anything you want: You can put him in auto mode, you can put him in pet mode, you can put him into pointing dog mode. You're not limited to only run one type of dog nor must you have every dog on the same update rate.
Customize the Maps on Your Astro 320 on the Fly
Worldwide DEM basemap - Not TOPO, but better than the 220
The biggest difference between the Astro 220 and 320 is the maps. The Astro base map has changed drastically.
The Astro 320 features the Worldwide DEM basemap. It has more shading, more roads, and more waterways. Now, don't take that to mean that it's a topo map, because it's not. It's just more detailed than the base map we've had before. It's a little easier on the eyes, too, as far as when you're looking at it. I just like the color combination a little bit better.
Customize the DOG MAP to your liking...
Plus, the Garmin Astro 320 gives you the ability to customize the dog map to fit your specific needs for better dog tracking.
Probably my biggest complaint with the Astro 220 is how you view your dogs on the map. Garmin designed the original product with the use of two dog screens. You have the Compass View which tells you the direction and distance the dog is from you, and you have the Map Screen which allows you to see where the dog is and his tracks. On the map screen you can see where he has been and how he is covering the ground.
From the Map Screen it is difficult to tell how far away your dogs are from you, and you have to watch for an update or two to have an idea exactly what direction they are moving in.
The other problem with the Map Screen is that the dog trail history is on the screen as well as the trail of your own track. The screen can quickly turn into what I like to call a really messy finger painting.
Add multiple dogs to the mix and the next thing you know, you've got four trails crossing over each other over and over. It doesn't take long for the screen to get so crowded, that you can't tell what's going on. The advantages of the dog history can become a liability in these situations.
I have been known to clear out a hunt and start over in the middle of running dogs just so I can start with a fresh screen.
Garmin has addressed all these issues in several different ways. My favorite part is that you can change the Map settings on the fly from the handheld with a quick push of a button.
The Dog Trails now have three settings to choose from:
When you start running in the Map Screen, the Astro 320 will show the complete dog trail history.
- complete history,
- partial history,
- or no history at all.
At the point you want to go to partial history, simply press the MAP button once. The dog's trail now only shows the last 5 minutes of history. Press the MAP button once again and the dog's entire history will disappear. Press the MAP button once more and the complete history returns.
This gives us the best of all possible situations. The advantage of this new feature is that you have ALL the history all the time if you want it, but you can control the amount that you see at any time. You can also completely blank the screen if it's in the way.
I could not be happier with this particular new idea.
It's much better than anything I have suggested or I have heard from other users. It's even better than Garmin told me it was going to be. A big advantage of this new feature is that more users can store the entire day's tracks in their unit without having to clear them out at the end of every round. Since you can get them off the screen at any point, you will be able to keep up with the entire day better and have a much better understanding of how your dogs are hunting.
The other cool thing about the partial history is that you control the length of time of the partial history.
You can select between 5 minutes, 10 minutes, 30 minutes, 1 hour or 2 hours. I expect the 5 or 10 minute option is going to fit most folks really well, but we will have to see on that one. It's easy to change in the field so you can experiment with it and find the right set up that fits your needs.
Map Icon and Viewing Options on the Astro 320The Map Screen gives you a number of Icon Options. The Astro 220 Map would show an image of the dog that would indicate the dog's status. If the dog were running it would be a running dog. If "on point" the image would show a pointing dog. If "treed" then the image was of a hound on a tree. If sitting, we had a picture of a dog sitting. You would also have the name of the dog.
The new 320 Map gives us some choices on what we see and when we see it. From the Map Screen, press the MENU key. This opens up several Map options. The ones that control Map icons allow you to pick between Dog Status, Dog Distance, Dog Names and Offscreen Dogs.
Show / Hide Dog Status -- Using this feature, you can remove the dog status Icon and replace it with a triangle that is pointed in the direction that the dog is moving. Replacing the Dog Status image with the colored triangle does not eliminate the point or treed alarm and it does not change the icon image on the Compass screen.
Show / Hide Dog Distance -- One of the things I hated the most about the 220 Map screen was the issue that you could not easily tell the distance of the dog from you while looking at the map. With this new option, you can include the dog's actual distance from you on the screen. You can see him, his trail and his distance all at once.
Show / Hide Dog Names -- This next space saving option is the choice of showing the dogs name on the Map screen. With the 220 it was always there, but with the new software, you can remove it with one click. This also really cleans things up and makes it easier to see the color coded dogs. Names will still appear on the Compass screen.
Show / Hide Offscreen Dogs -- This might be my favorite of the bunch. The biggest problem with the 220 map was that once a dog got a long way out, he would go off the screen. To find him on the map, you would have to use the page out button and you would have to press it over and over again until you found him. The new Map has the option of showing "off screen" dogs. When you activate this option, once a dog leaves the map screen you are on, a small tab appears that shows where the dog is in relation to your MAP screen. As you move the MAP around or as the dog changes locations, the tab moves with him. This tab will also show the same information setup that you have for the dogs on the screen. If you have name and distance turned on then they will show on the tab. If you have them turned off, then the tab will be blank, but will show the dog's color so you can tell which one it is.
Another map view option is the Zoom Map to Dogs feature. When turned on, the unit periodically checks to see if any dogs are off screen on the map. If so, the map will zoom out to a level where all the dogs are visible. You remain centered on the map. This feature will only result in a zoom out. If 'IN' or 'OUT' is pressed, there will be no checks for off-screen dogs for the next minute. If any of the arrow keys is pressed, panning mode is entered and off-screen dog checks are disabled.
What's really cool about all these new settings is that you can change them on the fly in the field. All of these settings can be changed from the Map Menu. If you want them, show them. If your screen is getting a little crowded, hide all the options. It's up to you how the screen is set up. If you want dog names, great, activate dog names. If you want distances, activate it. If you want to clear them off, clear them off. You can toggle back and forth between them all. It's flexible, it's easy and very intuitive. I'm pretty excited about that. It really makes the map much more versatile than what we have on the Astro 220.
View Garmin BirdsEye Satellite ImageryIn addition to topo maps, Garmin has added the option for loading highly detailed Birds Eye Satellite Imagery into the Astro 320. By now, most everyone has seen Google Earth, and the Bird's Eye maps are very similar. For $29.99 a year, you can download these aerial images into your Astro 320.
From Garmin's website:
Quickly transfer high-resolution satellite imagery to your Garmin handheld device to get a true representation of your surroundings with a 1 year subscription to BirdsEye Satellite Imagery.
Use your BirdsEye Satellite Imagery subscription with BaseCamp software to quickly transfer an unlimited amount of satellite images to your Garmin device and seamlessly integrate those images into your handheld's maps whenever you need them. Transfer an unlimited number of satellite and aerial image segments to your device with this subscription and free software BaseCamp. High-resolution sub-meter color satellite imagery captures the world in brilliant clarity and detail.
Allows you to layer the Garmin vector maps on your handheld (such as TOPO 100K, TOPO 24K or City Navigator) with BirdsEye Satellite Imagery for a real-life view of roads, buildings and terrain. Makes it easy for hunters to perform preseason scouting, determine placement of stands and locate game pinchpoints. Helps hikers and campers find trails/trailheads and clearings for camping areas. Lets geocachers determine the terrain type around a cache and identify parking areas close to the caches. Allows travelers to view tourist hot spots and landmarks from an aerial view to make excursions memorable without getting lost.
Now that is an interesting idea. I've been experimenting for awhile using my iPhone and Google Maps for satellite images while hunting in places that have roads that are not marked on a map. You can see them from the sky, you just don't have a map.
On my iPhone I can see myself and I can see the Google image, but I can't see my dogs.
Now, if I want to, I can get the Bird's Eye subscription. This feature is really going to come in useful for folks in large hunting clubs. You will be able to see roads, tree cover, power lines and waterways. You'll also be able to track you dogs on the exact same map.
The cool thing is that it's going to show roads that appear from the sky that are not actual roads. It's going to show power lines, tree cover, buildings.
The thought of seeing my dogs on a BirdsEye Satellite image is really, really interesting. I have not had a chance to experiment with this yet, but I think Garmin has got a lot of cool things going on here.
In addition, many state wildlife agencies have started offering free downloadable maps of public hunting areas, so you always know if you’re on legal ground. There are also some excellent third party maps that Garmin sells that work on the Astro.
With the Astro 320, you can even create your own Custom Maps. Basically, it's a matter of scanning a paper map, georeferencing it, and then loading it into your Astro 320. It's the best of both worlds -– putting a trusted paper map inside a GPS unit.
Best of all, each map is a different "layer" on the Astro, so you can view each map individually on the display, or together.
Power Button ControlsOn the Garmin Astro 320, you can access a few controls using the power button.
A quick press of the power button and the info screen shows you Time and Date. It shows the setting for the back light and allows you to increase or lower it.
This screen also shows GPS reception for the handheld plus handheld battery life.
Another of the advantages on this unit is that you can lock the keys.
A quick press of the power button takes you to the info screen.
Press the "out" button to lock the key pad. This keeps you from accidentally changing any buttons or
To unlock the keypad, a quick press of the power button takes you back to the info screen. Press the "out" button again to unlock the key pad.
Astro 320 Dog Alert OptionsA new option for Dog Alerts is Vibration. The Astro 320 includes a vibration motor. This allows you to pick from alerts that are tone only, vibration only or both tone and vibration. This can be a handy feature especially in the winter if you are wearing gloves or thick clothes. You have the option of having different alerts for point, treed, lost
communication and lost GPS signal.
Share Your Dog Info See the Garmin Astro 320 COMBO, Garmin Multi-Dog Systems, Extra T5 Collars, and the Garmin Astro 320 "Handheld Only".
Another new feature on the Garmin Astro 320 is the wireless sharing of dog lists.
When I meet up with somebody and we're going to hunt together and we are both running Astros, I want to watch his dogs and he wants to watch mine. With the old Astro 220, We have to go through adding all his dogs to my unit and all my dogs to his.
Even after we have added the codes we still don't have the names or other info. It can be a real hassle.
With the Astro 320, we now have the ability to wirelessly share dog information.
You set your 320 handheld to receive information and then your buddy takes his handheld and goes down the dog list and picks which ones to transmit over. It doesn't send every dog, just the ones you select. It's pretty slick. Gives you all the info really fast.
We are looking forward to experimenting with this some more.
Increased Onboard Memory Capacity in the Astro 320The Garmin Astro 320 has of 1.7 gigs of onboard memory. This allows you to download maps into the system without having to add an additional SD card. The card slot is still there in case you need more storage.
Battery Life in the Garmin Astro 320 HandheldThe stated handheld battery life is slightly less on the 320. It still uses AA batteries and Garmin is saying less than 20 hours from a set. I'm assuming that's got to do with all this stuff they've added. The screen is a little different. The backlight is a little stronger. The color is a little different. The base map is a little different. Use of the vibration motor is going to affect battery life.
From what I can tell, these added features are really going to drain your standard AA batteries faster. Just with regular use, I keep getting warning messages that my batteries are too low for the constant backlight feature. I think that looking into the use of Lithium AA batteries or the Garmin rechargeable batteries may become a bigger issue with the 320. I have used Lithium Batteries in my 220 and I am testing rechargeable AA's now. I have been pleased with both and I expect more folks will try them out in the 320 handheld.
The Astro 320 Includes a Long-Range AntennaGarmin has changed the range listing for this unit from seven miles to nine miles. That is 100% based on a new 13 inch flexible long-range antenna that is included with the unit. Current tests are showing that it will double the range of the standard antenna.
For example, most people in most terrains can get about 1 to 1 1/4 mile from the Astro handheld with the standard 5 inch
antenna. This new antenna, which is almost triple the length of the regular, will get double the range in similar situations. If you're getting a mile with the regular antenna, you should get two miles with the new long range antenna.
We still have a lot of tests to do for range, and I'm not 100% sure where I stand on it. It's included in the price, so I think it's something that's reasonable and needed. Please note that you are not going to get more range than the 220, you just have another antenna option. We can't get 7 miles out of what we have now. We aren't going to get 9 miles from this unit.
The new flex antenna is a little long for me personally to carry for regular use, but I expect some folks will go to it as their normal antenna. The biggest advantage is that it's the only long range antenna on the market that won't break. All the others that we sell have to be handled with extreme caution. This one is super tough. It will take the abuse and keep on tracking. I expect that I'll continue to use the regular antenna unless I get into a situation where I need it. For a lot of the hound guys this will be a nice addition.
Screens and Icons on the Astro 320You have two choices of screens to look at the dog's location and you can move back and forth. The MAP SCREEN (first screen) shows your location, any "way points" (think truck, food plots, hunting lodge, blinds) and your dog's location, plus it shows your dogs "route." NOTE: If he likes to run in circles, you'll know it.
Since you already know where you are (at least let's hope you do) it's more important that you know the direction of your dog(s) and the distance, as well as what he is doing. The COMPASS SCREEN is the best way to keep up with a larger number of dogs because it shows your direction as well as a different color line for each dog showing direction, distance and status (running or on point).
You have two options on the Compass screen as to how you view the dogs. You can either see multiple dogs at one time (up to three) or you can tab back and forth to see them individually on the compass.
