Summary: This is a great unit. I took the LAKEMASTER ProMap chip out of my boat GPS and it works great in this unit for ice fishing. The accuracy and detail is amazing. It takes a little longer to hook up with the satellites than some units, but other than that it outshines all other handhelds I looked at. Plan to use when I go cycling this summer.
Awesome GPS unit! Easy to use with great features.

Summary: Awesome GPS unit! Easy to use with great features. Great price on ebay. Great on land and the water. Has many uses such as geocaching. Easy connection to my computer. Uses micro sd card great for uploading maps of the detroit river and local lakes. Lots of potential for upgrades.
Summary: Has many needed features I was looking for, but I couldn't upgrade the system to accept new chips for fishing. maybe the program I'm running on my computer. We'll see until I try on a nother computer.
Summary: Well with the advent of iPhones and car GPS devices these high powered handhelds for the extreme users do seem to be outdated in there performance when it comes to user interface. Once I learned the lingo and how to be patient you can really see how much fun these are on the trail.
