By: Thomas Floyd From NEI had the Garmin TT10 GPS collar and ordered the upgraded TT15 GPS collar from Gun Dog Supply. I guide upland bird hunts for several preserves in Nebraska, so use the Garmin Alpha collars extensively. The TT15 boots faster than the TT10 and does not lose GPS signal as the TT10 sometimes did for short periods of time. The range is also longer on the TT15. Another feature of the TT15 collar is that it has a vibrate mode in addition to the tone and stimulate modes. I'm very pleased with the TT15, and the customer service of Gun Dog Supply. I order all my hunting dog equipment from Gun Dog Supply.
