I'am installing a new fishfinder with a speed sensor on our '75 Beachcraft, and have two questions. One, can the speed sensor be mounted on the same side of the boat as the transducer? If so, how far apart should they be. Two, the current transducer is mounted midway between a strake and the side of the boat (about 6in from the side). Is this an OK location, or would it be better more toward the center? I don't know how well this location worked for the old fishfinder. So many columns of pixels were missing it was unreadable (came with the boat).<br /><br />Thanks for your help!
