This unit works great. Helps me keep my dogs away from the highway. Also dont have to worry about my coonhound coming back when hunting......always know where he is. Gundogsupply is a great company to work with.....fast shipping!!!

Collar picks up quickly and updates often as dog is traveling. Great options for correction too with tone, vibrate, and stimulation.

This a great tool for training and keeping track of your dog in the field. In my case, the north woods.
Gun Dog Supply's typical great price and service sealed the deal.

So far this unit is packed with great features not as intimidating as when first out of the box. Became easier to use as I played with it.

This was my third Astro, the first one with the training feature in it. As always Garman products it was easy to set up, and works exactly as you expected to. A great product well serviced through Gun Dog Supply who were great to do business with.

I have had this system for about three months. Have used it in the field for training while trying to learn the various features before hunting season. I like the tracking feature using the compass. It has many bells and whistles that I doubt I will ever use, like finding nearby restaurants. I plan on downloading better maps before going to KS. It takes a bit of getting used to, especially changing the level of correction. The only negative I have experienced is the amount of time it takes to get the collar and handheld communicating with each other. I live around a lot of trees and it doesn't seem to work too well in the trees. But my hunting will be on the plains so expect it will do fine. I would recommend it for the tracking.

Works good

I don't care for the long antennae. It seems like to takes a very long time to charge the transmitter.
It came with a black collar instead of the orange collar I had to buy extra.

Instant notification when my dog is out of site. I know immediately what the dog is up to. It eliminates the need to call the dog back because you don't know where or what is going on. My biggest fear is to lose my dog while hunting. This unit eliminates that fear. There are features in this collar I will probably never need to use. The screen is very easy to view even in bad light. I like the vibrate mode on the collar as my dog responds very well to it when activated. I have not and to not intend to use the stimulation mode and have removed the prongs and placed the plastic cover in their place.
Very pleased with the collar and the fine people at Gun Dog Supply.

The screen changes randomly. The e collar buttons change the screen when activated/ pushed.

It works well very easy to work with.

Works great especially while training puppies.

Only problem I have with the system is I think we have to many Garmin collars in our area. We have up to two hundred or more in 10 to 15 mile radius. At times we have trouble with collar linking up with alpha and having problems during the hunt tracking dog. Have any suggestions?

I live in mountainous terrain, and keeping line-of-sight is not possible; however the Garmin TT15 maintained contact with my dog. I was able to track my dog over hills, and deep into ravines. I was quite surprised at how well this GPS performed.

Works as advertised. Nice to track dog when hunting grouse woods.

My husband has trouble reading the screen and wishes it were larger. He is slightly vision-impaired.

Very impressed with the product!

Great product with too many features for just a hunting dog in my opinion.

It needs a little bit of work with the interface and usability. It's great for tracking but the handling end leaves a bit to be desired. All in all it's a very nice product so far. But it could use some improvement.

I was against shock collars for years but I have changed my tune. It shorten the training time greatly and does not harm the dog. I use a tone for the come command when the dog is out of sight. I use vibrate to get his attention for hand commands and I use the shock for sit and to get his attention for commands. The tracking is a great feature. It was the best training tool I have come across in 30+ years.

This product is very nice for tracking multiple dogs and making corrections in the field. I would have rated it 5 stars, but I think the feature for handeling multiple pointing dogs could be improved. Too much time is wasted if needing to increase stimulation levels. Vs the traditional dogtra or Tri tronics products, regardless of how you have the handheld setup. But if wanting to consolidate tracking and training collars into 1 this is the best on the market!

You guys run a first class operation. The alpha 100 is best of all dog GPS gadgets.

This is the best thing I have ever bought. Gun Dog Supply are helpful and good people to work with. They ship fast and you get everything on time. Couldn't ask for a better company. In love with my new Garmin. It might be a lot of money but by far worth it. I recommend this to any hunter that hunt with dogs.

I have not really had a chance to use it yet

Ordered for my husband. It was a great price and I received it two days after ordering. The device was pre-registered, which saved time in downloading maps. We are very satisfied with device. We have ordered other products from this seller, and will continue to. I recommend this device and company to others.

I just love the Garmin Alpha 100 with TT15 combo! It does all it says it will do. Thank you! -Deborah

The Garmin Alpha 100 is exactly as advertised. It sure beats wondering where my Beagles are, especially with the wolf overpopulation out there. You can't let those dogs get too far from you these days.
