I really like the specs on this new Garmin combination unit called the Rino 110 or Rino 120. (For those of you not familiar with it, it combines a GPSr and an FSR Walkie Talkie in one unit). It has some pretty nice features. But before I plunk down cash for it, I'm wondering if it has the sensitivity of my present Garmin GPS76. Anybody used one? Seen one in action under tree cover, etc.? My Garmin 76 works really nicely under tree cover, etc. I don't want to trade that sensitivity and accuracy for this new one just because of a built-in FSR transeiver. Any thoughts, comments, first-hand accounts?
