I have one and I'm not sold on it if your on the deck it's fine. To operate but if u can't see the head ur in trouble I've been waiting for a year to hook it up to the Lawrance unit to follow contour lines. There is a good delay on the anchor lock but it does hold good. The other think it seems to not hold the auto direction that well. Could be the operator. The plastic seems a little lite to hold up over a long period. Just my 2 cents.
