I have an alpha system with some TT10 collars and am pleased overall with the performance.. Could stand a little more range at times. My question is for those of you that have both types is there a noticable differece? Is the 15 worth the extra money? I am looking to add some collars to my system in the future but wanted some hunter feedback not just the specs..

i have 12 t10 3 of t15 if i was too buy any more i get t10 because price difference no differene in range that ive seen avg 2-3miles

I LOVE my TT15 for the Bark Indicator! Nothing like a pop up box on the screen telling you which dog is barking more the 20/40/60 times a minute. Especially if you are on the move and can not get an ear on them.

Hurley, what are other reasons why the 15 is better than the 10?

Chuck I have not noticed any difference in the distance between the collars yet but where I got my collars from the TT10 and TT15 were the same price. So when I went back to get more collars I got the TT15.

Also the TT15 and TT5 can be tracked by the 320 and Alpha (not at the same time) So if I had a 320 I would be buying the T5's so if I ever upgraded I could keep using the same collars.

Hurley, good write up. Thanks.
