    Great training aid!
    January 14, 2025
    The Garmin plus 550 with the Tt15x collar is all that Garmin said it was. Easy to set up and easy to use. My dog cain't wait to have the collar put on and get to work. He went from watching him run in the woods to a good hunting companion. Thank you Gun Dog Supply and Garmin.

    Gundog supply was a great resource to both educate myself on what product would work for me and ordering. It was the best price I found and I recieved the item quicker than expected. I've found this website to be the go to place for supplies for my new upland pup.

    Garmin Pro 550 Plus & TT15X are a Game Changer
    December 16, 2024
    I recently purchased the Garmin Pro 550 Plus and TT15X for my Brittany and the system is a game changer! I had used another brand's training and beeper collar, but the Pro 550 Plus has the functionality of a training collar for quick correction and provides immediate location data without listening for the beep. The receiver vibrates when she's on point, and gives me her exact location. Finding my dog in heavy cover when she's on point without the beeping that can spook late-season roosters has meant more birds in my game bag. It's easy to set up, easy to use, and just what I was looking for. The added bonus is a quiet hunt in the field, enjoying time with my friends and my dog.
    Pros
    • Simple setup, quick and easy to use correction functions, and knowing immediately where my dog is. I hang the Pro 550 Plus on a D-ring on my vest so I can look down and quickly know her location and whether she

    Works great. A little slow to connect. It's nice that it works with my old 430 as a tracker. Battery level indicators are a plus. Collar a little large for my little GSP but fits most others better. I like being able to mark my trucks location.

    Nice, but bulky.

    This is my first E-Collar, for my first retriever. I wanted to be able to navigate back to the truck/boat, as well as locate my dog if need be. Takes up to 7 minutes to find a satelite and connect to collar. Still learni g the fuctionality, as well as my dogs working levels. Well made, just a bit big for what it does in my opinion. Would buy again.

    Great package deal. The frustration of losing your dog and spending half the day looking for him convinced me to spend the money on this collar. Worth every penny IMO. GPS is a game changeAlso,the company is great to work with. Good family owned business. That's why I purchased from Gun dog supply! Exceptional service, thanks for helping me out.

    good but slow access to collar
    December 24, 2025
    garmin handheld takes a normal amount of time to acquire gps signals however it takes forever to connect gps signal of collar. Holds signal well once connected. I would suggest getting a cup of coffee while waiting for handheld and collar to communicate with gps signal. tone, vibrate side of collar access is virtually immediate

    We hunt some thick stuff up here in Montana and knowing where my dog is when out of sight is a real advantage .My only regret is I didn't get one of these when I got my lab to start with, very easy to use and her response to the tone feature is much better on this model than the lower priced one I previously was using. I do wish that a good quality lanyard was included .
    Pros
    • Good range
    • Easy to use
    • Wide range of correction levels
    • Tone is easy to hear
    • Dog responds well
    Cons
    • Does not include a lanyard

    Gave me the confidence to let my dog roam and hunt
    November 17, 2025
    I just purchased this unit with enough time to figure it out and then hunt for 6 consecutive days on both waterfowl and upland game. I was used to the old Tri-Tronics devices and this worked about the same when it came to the training part. My dog figured out the beep and I rarely had to move to anything else unless she was really distracted. The GPS feature is enough to let you know where the dog is, but at times it was off in both direction and distance. I calibrated the handheld each day and sometimes multiple times when I saw it was off. Several times the north indicator was off as well. All that said, I get how GPS works and for what I needed, it worked well. Not perfect. Just well. I could tell if my dog was ranging away or back toward me and in general where she was. She is a 13 month old lab and did a great job on her first hunting with 5-6 duck retrieves each day and multiple pheasants flushed each day. In my research, this was the best GPS and Training collar for the price. I am not a fan of the wire antenna on it, but it is what it is, and it does work well.
    Pros
    • Range
    • Very good training collar controls
    • The light on the collar is great when you are letting your dog out at night
    • Set up was very easy
    • The beep in addition to the stimulation allows you to get your dogs attention before you issue the command
    Cons
    • GPS accuracy

    Happy with the Garmin PRO 550 Plus
    November 5, 2025
    We adopted a young Plott Hound and needed a new collar to replace an older training-only collar we used with our previous Walker. The old collar did not have GPS tracking capabilities, and that was something I really wanted in a new one. I did a lot of reading and research on many different brands and models, along with cost vs. features. The Garmin Pro-550 Plus checked all the boxes for what I was looking for, and the videos and reviews provided on the website were absolutely wonderful.Having had the Pro-550 Plus and TT25 collar for a while now, I am very happy with it. Setting it up was not too much of a hassle and once the devices are paired, communication between the handheld and collar has been flawless so far. The controls for correction are easy to use and adjust. For the GPS/tracking side, it is a simple tracker with a directional arrow to follow. Acquiring GPS location is sometimes fast and sometimes takes a few minutes. Direction and distance are not 100-percent accurate and can bounce around quite a bit, but good enough to locate my dog easily. Overall, I am very happy with the Garmin Pro-550 Plus and TT25 collar combination.
    Pros
    • - Once it is set up and paired it is easy to use
    • - Training features and controls are easy to use and adjust.
    • - The lights on the TT25 collar are excellent for nighttime use
    • - Can pair with the Garmin Explore app for mapping features
    Cons
    • - GPS directional arrow will bounce around a lot

    First trip out was South Dakota pheasant hunting with a group of ten. The ability to know where your dog was at all times is fantastic. Being able to tell the other guys my dog was on point near them was fantastic. The thick cover that makes the dog disappear within feet, is revealed with the garmin pro 550+ Best purchase I've made for the security of my dog. No more yelling for a dog you can't see in the thick cover.
    Pros
    • Point alert! Direction arrow and distance!

    Works perfectly, instructions need improvement
    October 23, 2025
    The decision to buy the PRO 550 Plus and TT25 was a good one. I did my research, every feature of the product works perfectly, and Gun Dog Supply answered a couple of questions very quickly. All in all, this was a good purchase.Garmin's instructions are severely lacking. Having never used a device like this, it took me days of trying to find a tutorial without success, and then another couple of days of experimenting to learn how to make it all work finally.
    Pros
    • Excellent quality and durability, with excellent support both online and in the spare parts that are offered by Gun Dog Supply
    Cons
    • Instructions.

    Exactly what I was looking for
    September 16, 2025
    I settled on this unit after hours of research, and talking with friends that have used many various makes and models. Most influential was Steve's Gundog Supply video. 5 stars for both the Garmin unit and Gundog Supply for ease of purchase and excellent customer service.
    Pros
    • Easy to use, simple to use features:
    • Vibrating 'point' alert to the handheld receiver
    • Arrow and feet/yardage location to the collar
    • Easy set up
    • Handheld receiver has simple, easy to find buttons and selector switches without looking at it
    • Long battery life between charges
    Cons
    • Could come with a lanyard, but I get that many users just purchase a holster, and the lanyard accessory would add manufacture cost and not used.

    August 16, 2025
    When training, timing is so important.With this set up , I can concentrate on training/ correcting my dog without the distraction of dealing with more information and controls than I need.I can easily switch between modes and multiple collars. My dog hunts fairly close so I don't need the mapping feature.But it is handy knowing how far and which direction he's working when he's out of sight. Also alerts when he's on point.
    Pros
    • Easy to use.

    Peace of mind
    February 21, 2025
    I traded up for a 550 to the plus for the tracking capability. It's a little slow to update on the position of your dog is moving fast but it will keep you close enough. I use it with a waterfowl retriever. It just gives me piece of mind if I let my dog chase a cripple out of sight when hunting the timber or other heavy cover. A long time ago a hunting partner lost his dog that way. I see some people complaining about the antenna length. I run the antenna through the collar buckle that keeps it from flopping around. My only complaint is that the time button isn't loud enough. I use the tone to call my dog back in at long distances. If he is running in water he don't hear it.
    Pros
    • Works at it should button placement is easy access range is great
    Cons
    • Tone button is soft, not loud enough.

    This combo is a perfect, no frills, gps collar for my dog. When out hunting birds I wouldn't have time to look at a screen with a map...just direction and distance is all I need. The handheld device also tells me when my dog is on point. I would recommend this product and would recommend Gun Dog Supply.

    This replaces another collar that required a smart phone app to monitor and send corrections making it difficult to send quick corrections. The 550 plus has everything I need right at my fingertips for a quick correction plus a simple screen with GPS direction and distance to my dog. The correction buttons took some getting used to since they are not labeled and the instructions are poor. However, Garmin support was great and they sent me an email with better instructions on what each button does, specifically on how to achieve high, medium, and low correction for each dial position.
    Pros
    • everything I need right at my fingertips for a quick correction plus a simple screen with GPS direction and distance to my dog
    Cons
    • Instructions are poor on how to access the various correction levels (2 large black buttons), you may need to call Garmin support.

    Generic manual doesn't help operate
    November 15, 2023
    Manual and YouTube shows no detail. I'm left to guess. When I first operated I didn't know you don't have to pair collar each time. Nothing tells us about how to turn on controller, long press on switch, sort press, momentary switch? So, you don't know when to stop pressing button. Needs idiots guide, but I guess it's too much to ask idiots to write that.
    Pros
    • Once you figure it out, it works nice.
    Cons
    • Manual is a joke. It states obvious , but no set up guide or detail step by step for first time users.

    Not what I hoped for
    November 15, 2023
    I had hoped that the tracking would be a little more accurate between the Pro 550 plus and tracking collar. The TT25 is too large for my small French Brittany. Hoping Garmin brings back the TT15
    Pros
    • The Plus 550 is easy to use
    Cons
    • The collar is too big for my small French Brittany. Not always able to have contact. It's unfortunate that Garmin doesn't have the TT15 anymore.

    This collar does exactly what I need. Dog location, distance and the ability to correct in a simple to use platform. Will be buying 2 more collars to complete it.
    Pros
    • Very easy to set up and use.
