I have two boats, my bass boat and a kayak when I`m in the kayak I would like to be able to set waypoints on spots I find when fishing and then manually enter them into my Humminbird on my bass boat.

Can any one recommend a small hand held gps device I can get?

I must be able to see the coordinates so I can then enter them later. Just not sure if all units show that?

Thank you for any help!
