I set my calibrated DS warning signal to 5'. With the sender approx 12" higher than deepest portion on twin screw planing hull boat's bottom (i.e. the props/rudders) that leaves me approx 4' underneath all items. Therefore, I then go very slowly when beginning to listen to the warning signal whenever entering fairly shallow water – the ongoing sound makes me keenly aware to keep close eye upon “bottom look” off fly bridge, as well as the readings on DS screen. If screen shows 4’ or just below I immediately go into reverse and back out at low idle till safe depth is reached.
