ClearVu transducer specs

[LWINCHESTER2]

If I had a choice, I would pick the GT52. Here's why. When people get so caught up in the improved detail of down imaging (HB) , Downscan (Low), and DownVu-now ClearVu it is because of that very narrow front to back degree angle. It varies by brand and transducer from 0.8 to 2.0 degrees. Neglected from that consideration is the width of that same cone which may vary from 30 degrees to better than 50 degrees. It is that measurement that defines the dead area, next to the bottom, that you cannot see because it is blacked out as the bottom. Where I fish, most of the time the wind controls the orientation of the boat and generally that means the boat is oriented parallel to the bank. That is the worst performance of all the so called down sonar implementations as far as seeing close to the bottom is concerned. So for me, a narrower width is preferred. On flat terrain, a wider come may be preferred by some to get the additional coverage. To use down sonar most effectively and to get the smallest dead space means to orient the boat as pointed directly at the bank or directly away from it. Also notice that the dead area limitation caused by the incline on the starboard side also extends over to the port side as well. In the example sketch, notice that the actual bottom is 100 ft deep. I should have had Larry do the sketch. He does a much better job and probably has one already made.

Totally agree, thanks for clarification.
