I am selling a brand new, still in the box, Magellan Triton 400 Adventurepack handheld color GPS. It has a 2.2" color screen, SD card slot (512 MB card included), USB connection cable, and 25 National Geographic TOPO Explorer map credits. Also has carrying case included. I have added the link to Magellan's site, scroll down to the 400 Adventurepack, retails for $249. http://www.magellangps.com/products/product.asp?segID=425 Asking $165, with free shipping. PM me if interested. I have a Humminbird 727 that is GPS capable with and external GPS reciever. I will be using one of these Magellans for the GPS reciever, avaliable lake maps, and easier transfering trackplots to my home computer, just need to order a NMEA data capble. This was a cheaper option then upgrading the fishfinder right now, and gives you GPS capability.
