Grouseman 4 out of 5 10.30.2014 at 1:06 am Outdoor Dog Supply is awesome to deal with. They were very polite and my order was correct. They offer more choices (i.e. collar color etc.) than the other / larger stores for the same product. As far as the system goes, it is O.K.; but Garmin needs to “tweak” it quite a bit. First off I hunt ruffed grouse in MI, NC and TN, in some very thick cover and mountainous terrain. This system allows us to quietly hunt the late season and still keep track of the dogs. Also, it easily allowed me to recover 2 dogs that had gotten too far away on a very windy day However, the GPS loses signal frequently; but regains it quickly. The volume of the system can NOT be adjusted, you can only pick a different tone. The loudest tone available is still nowhere near loud enough, especially if you have any hearing damage whatsoever. If you are buying this system to for hounds(I’ve done that also), you will probably love it. If you intend to use this system for bird hunting, I would suggest investing in beeper that will function in a “point only” mode, to go along with it. Overall, I would recommend this system; however it is VERY expensive and could use a little tweaking.
