What transducer does your electronics need? Use that one

With that large boat you do realize any transducer will tell you what it sees directly beneath the boat - not what's ahead or behind you. In other words they are good at warning you right after you run aground or onto the rocks unless you really pay attention to it's readings while under way. It the depth is increasing -- ok to hammer down. If it is decreasing, better be looking for deeper water or chop the throttle until you figure out where you are regarding the charts.

You can use your cell ( might need a app to get that feature ) to measure your dead rise , I would guess your in the 12* - 15:* range . Bigger older boats usually never got close to the somewhat standard 19 * Doesn't Airmar only offer 2 models for different dead rises ?

Asking for dead rise degrees , not frequency for his MFD .

That is what an angle finder or digital level will tell you as deadrise changes from bow to stern

Multiple models but only two deadrises, 12 and 20 degrees

Then 12* is what he needs , no way did they make that dead rise close to 20* more like 10* the more I think about it .

Found mention of 14 degrees in early model but by 1989 the brochure specs transom deadrise at 17 degrees
