In the original configuration of Harold, Maynard attached a transducer to the front of the starboard side thruster. I assume he did so as a way to easily shift direction, up to get depth bouncing off surface, spin the thruster down for depth, forward for collision
avoidance.<br clear="none">

1) transducer always pointed up for a Humminbird HDR 650. Basically a digital depth gauge. Small and accurate. Works well.<br clear="none">

2) Raymarine Dragonfly 4 Pro aimed down to give depth below and detailed image of what's under me. Amazing little CHIRP sounder.<br clear="none">

3) still debating on what to aim forward. Currently have an Interphase forward scanning sonar, but not real impressed with it. Older technology that works. Sort of.<br clear="none">
