Summary: The instructions are skimpy at best. You should plan on spending time doing trial and error to set temperature, time, etc.. The symbols on the buttons are indecipherable. And nowhere do the instructions tell you that you have to eject the device just like an iPod and not just pull the USB cord out of the computer and/or the device. If you do you'll get a nasty error message. Having said all of that I used it this morning for the first time and it seems to be okay.
Summary: One year ago I purchased a bushnell backtrack and was pleased with its performance. I primarily just wanted something to get me to my hunting spot and back to my truck and this unit worked fine. My oldest son is 16 and was going to be hunting alone this year so I purchased a Bushnell backtrack d-tour for him. On opening day he took my backtrack and I took the d-tour.
Summary: I got this before last deer season and it worked the first few times out but then the directional arrow went crazy and points nowhere near north with the compass nor back to the way points I set. The distance from the way points still worked so I was able to find my way back by making sure the distance was getting less. I need to send it back to Bushnell for warranty repair. They don't cover shipping to or from them which is LAME.
Summary: i had the older one. so when it died (it was passed down from my grandfather) i knew what i wanted to buy from the begging. great product, sat alight pick up is quick and it has got me out of sticky situations
Summary: After product finally gets a "lock" on the sattelite and way points are set, the unit almost always moves their location by up to 100 yards, in an unpredictable direction. It doesn't help me find my car in a large parking lot.... maybe i got a lemon...
