Don't have all the kinks worked out with the new boat just yet, but finally bought the new "compatable" chip Friday and the darn thing actually works. And, it's really pretty easy even for a pre-historic tech guy like me. You move the cursor to a contour line and press the GO-TO button. It gives you the option to FOLLOW CONTOUR and the choice of two different colors to choose-one for each possible direction. You pick which one you like and then the darn boat starts going around the whole lake---really neat! The new hand-held is a bit like carrying a portable TV around and requires a daily recharge....but charges quickly from the a 12 volt receptacle on the boat....I'm getting used to it really quickly and the options are amazing. I think the guys who guide are going to fall in love this and leave their wives! Marty Forman
