Rivercatcatguy, if its treasure hunting you wants to do with a GPS, then this is what I have to say about that. Never go treasure hunting with out a GPS. I am using the GARMIN 12XL that I carry in my pack along with everything else I could possibly need for a long day at the beach. However, I am about to move to the GARMIN eTrex, this little baby can do everything the 12XL can do but in half the size.
Additionally, I purchased the Garmin World map CD for my lap top in order to build a data base of shipwrecks, along with the artifacts that I recover up and down the coast. I am also set up to download and upload directly from the PC to the GPS unit.
I am currently researching the best options for a new GPS for the boat. Up to now I have just been throwing the Garmin on the fly bridge consol and navigating my way with that. This has worked out OK so fare. But my requirements for the boat are a little higher than for the back pack. First I will need a DGPS (differential GPS) aka WAAS enabled, a state requirement for salvaging in state waters. It will also need to be Blue Chart compatible, just because I like the idea of having my navigation charts on an electronic display.
I guess I should have the wife read this before Christmas.
