Hi guy's ,Just got my new boat (to me anyway) in the water and it has a Garmin 535 on it. I've never had a chart ploter before and was wondering if the bluechart was worth it or not. Seems to be directed to the lower 48, but I really don't know. Just wanted to ask before I tried the $250.00 experiment. Still can't believe its in the water after a two month battle getting it here, shipper took full payment and parked the boat in WI and never said a word, then claimed bankruptcy. All was saved by a young man that was the contract driver for the company contacting me even after he was burned for several thousand by the company. My faith in mankind renewed.
