Summary: An excellent concept; the unit has the basics I was looking for: compass, direction (as the crow flies) to a marked point, up to five such points so that you have way points to follow home, distance traveled on a trip and time elapsed, distance to go to a marked point, co-ordinates and elevation of your location, temperature. I would pay more if Bushnell would produce a better version.
Summary: I loved this little device. I use it for cycling/kayaking. It takes some getting used to. It has some peccadillos which you have to figure out. One, for example, is setting the time. It would never keep when I set it. Another is the miles window. Rather than miles or kilometers it is yards and meters.
Summary: It's pretty easy to use and a fun idea, and does what it says it does. But the user guides and software are pathetic. Ultimately, trying to import the tracks I recorded failed miserably, even after I uninstalled and reinstalled the software repeatedly, and the memory got erased. The help function is useless. I got an error message from the beginning saying initialization failed, and there was no guidance anywhere about it. The user interface is very primitive.
Summary: This is the second model that I have tried. First, the yardage/mileage is right on. I tested it on a measured 100yard range. Now for the sad part. The compass, even after several figure 8's to calibrate, seemed to want to point east rather than north. The backtrack to a marked location worked sometimes, but sometimes it was off by 90 to 180 degrees. Totally unreliable. I tried to contact Bushnell customer service by their E Mail address, but they never answered.
Summary: It probably works OK for the applications they're obviously pushing -- hikes in the woods, fishing trips in the back country, etc. But it's no good at all around cars, buildings, metal objects, etc. The GPS reading for the distance back to your starting location is accurate, but the arrow (even with lots of "calibration") is just as likely to send you off in the wrong direction as head you back to where you're trying to go.
Summary: If you want accuracy....not the best item to buy. Many times it takes 20 or more minutes to get satelite readings. And changing batteries is a pain as the back is not too easy to remove. I guess for the money it's ok......but for the serious hunter spend the extra money and go Garmin or Magellen.
