cpt100 cone of vision

[charlie98117]

I have a cpt100 transducer that came with my a78 MFD. I have a sailboat so I am going to embed it in fiberglass resin to shoot through the hull. I know that mounting is not recommended but I've tried it in in a bag of water and it seems to work well enough for my purposes.

My question is regarding orientation. Does the unit have a cone of vision that affects performance or readability? The best mounting location I can find for a longitudinal orientation is forward and a bit off center. I get bad readings when heeled over, I think it may be out of the water or close to that point. There is another location that is centered on the hull and seems to work on both tacks but it is a 90 degree transverse orientation. Does the orientation affect the information presented on the display?

Thanks, Charlie
