Handheld GPS

[cruizer]

Is there a hand unit that shows you on a lake for a reasonable price?

I've had the H2Oc with Navionics chip (don't remember which version) on my boat for a few years now. It's great and shows me exactly where I'm at all the time. Love it!

You can get the current handheld unit that Lowrance makes, the Endura, and download any GPX map file from the internet and use that chip in the unit for use on a lake. Map Select is a good website to purchase maps for example.
