Re: Threw hull Transducer location relative to center ???
Depends on what you want it for, depths encountered, and beam width. If you're picky, vertical is the only way wherever you can find that on your hull. The main thing is "non turbulent" water and in the area of the keel that could be a problem. Turbulence causes false alarms, course if you are only interested in where the bottom is, it doesn't really matter how many "fish" are on the screen. If you have a wide beam (20 degree) and in shallow water, vertical is not all that important either. Last, you want it submerged when running and the best place for that is forward of the transom.
