I think I know the answer... but figured before undertaking the project
... to get help from those more experienced .
As the title suggests, I am replacing an older (but working)ST50 tridata speed/depth/temp with separate paddle wheel
for speed and temp, and a separate depth
with a B&G transducer (DST800) with speed/temp/depth in one.
My original thought was to remove the paddle wheel
and pop the transducer in. However, thinking about it, the deadrise is pretty steep, so it will be firing at a steep angle and could give erroneous depth
The depth sending unit is mounted in a fairing and is horizontal to the earth, so the depth is accurate (at least when not heeling!). My original plan was to just abandon this transducer in the boat
Now I am thinking of installing the new transducer in the depth sounder
My question was will the paddle wheel work in the horizontal/fairing location? Or would the depth work firing in a higher deadrise orientation of the paddle wheel?
Also, any way to get the depth transducer out without damaging it so it could be reused later on (it was bedded with 5200)
