I've read or seen others saying to level the transducer to the water. Never figured out exactly how, but instead, leveled with the bottom of the boat even knowing, the bottom doesn't sit flat and parallel with the water surface. This technique is so simple, one of those times when you're a little embarrassed with a "Why didn't I think of that" moment.
Thank you so much!
I've got a Garmin 93sv UHD. That's a 9 inch screen. If I've learned anything from this thread (and the few trips I've tried it) is to get closer to where I'm wanting to scan, especially if I'm looking under docks. Been too far out and yes, not seeing much under the docks when I'm passing 20' or more off the dock. Seems so very elementary, just SV newb mistake.
