    Not only do these collars track as well as the tt10s they are a whole lot lighter and less bulky. The other great feature is the new sleeper mode which will give u over a week to recover your dogs if needed.

    everything is top notch on these collars . the only thing is the collar sleep mode the handheld has to communicate with the collar to wake it back up . if u leave the dog and come back and the dog has moved out of range u cannot turn the collar back on u will have to ride around in the blind to u get communication . sleep mode is good if u collar your dogs up put them in the truck then wake them up before u turn them a loose saves the battery life.

    I bought the Alpha combo prior to the TT15 Mini being available. I trial and train Brittanys and the large size TT15 was too big for younger pups. It was to the point that I quit using it on some pups.

    Outdoor Dog Supply has a great trade-in program and I took advantage of it to get TT15 Mini’s. When they arrived, I was surprised that they were the same size as my Pro 550 collars. I can not tell a difference in range or performance, but the battery life a bit less than the standard TT15, but not a problem at all.

    I am very pleased that Outdoor Dog Supply worked with me to get the Mini’s and am very pleased with the Mini’s. I would recommend the Mini to anyone who has mid to smaller breed hunting dogs.

    I give Outdoor Dog Supply and the TT15 Mini 10 stars, even though they only go to 5 **********

    At first I was a little bit skeptical when I heard the idea of a TT15 Mini Collar, but I like the idea of the lighter smaller size. As I collared up my dogs Saturday morning, I liked the fit on my two smaller beagles. I let the dogs loose and they jumped a deer and the chase was on! Listening to the dogs run I watched them make a few tight loops on the Alpha, then break straight and go out of hearing range. Watching the dogs on the Garmin Alpha screen, they were 2.5 miles in no time, and I only lost 1 bar of GPS signal making me very happy with the tracking on the new Mini collars. While letting the dogs run for a few hours and keeping a tight eye on the Garmin Alpha to see how they were running and the performance of my new toys…a.k.a Mini TT15 and Mini T5 collars. My overall opinion of the new Garmin TT15 and T5 Mini collars is these are top-notch collars! They tracked a consistent 2 3/4 to 3 1/4 miles with my handheld hooked up to my roof top antenna all day. I was very happy with these new Garmin Mini Collars – Robby Davis
