Most xducers are 20° but new technology are getting them up to 90°. The book for my Lowrance says it will go up to 60° by increasing sensitivity. If i had to do it all over I would just get the power drive and auto pilot and save some money. When mounting the xducer on the bottom of the motor, there really isn't a neat way of routing the cable up to the sonar because of the way the mount works. But I can live with that for now. When my warranty expires I'm going to attempt to remove the US and somehow put my Lowrance xducer in the hole. I talked to Tom Foster (Minnkota authorized dealer) in Suffolk and he said I should be able to get the cable up thru the shaft like the do the US cable now.
