I am looking for a simple gps for a boat. Nothing too special, no fish finder etc., just something recreational for lakes. No fishing gps please, just something easy to use and tells me the depth of the water.
I have a USB based GPS unit and a laptop. So rather than drop $1,000 on a marine GPS , I am hoping to find decent software and just bring the laptop out with me. Who makes good software for this? I am searching the internet but not finding a whole lot.
