I've had three of these for about 10 years. When they first came out I paid almost $300 and the last one was around $125. I've used them extensively as a pedestrian and in a vehicle. I literally took one around the world. The only place I took him where he wasn't working was on a drive near military training areas. Given the proximity, I'm not really surprised. First the pros; It works. Accuracy depends on many things, mostly cover, but it can drop to 15ft accuracy. Rarely more than 100 m. It is waterproof. I got up without any problems. It's small. Fits comfortably in a shirt pocket or harness pocket. It's kind of programmable, you can plan a route and then follow it. It's pretty durable. If you drop it on the forest floor, it won't break. minuses. The main disadvantage is that I had to replace them very often as the toggle switch actuator "arm" wears out and the unit fails after about 3 years of use. The second downside is that the display is grayscale and difficult to read. Especially if topographic maps are loaded in it. You can disassemble it, but it will be a problem for older eyes. I've used them for car navigation but don't recommend them. Especially in traffic jams. I sincerely recommend them now that they are cheaper. This is a basic, fairly robust GPS that works well enough for a hiker or hunter. I have a Garmin Nuvi that I use in the car, but for backcountry use I like this one.
