I've never had problems with transom mount transducers, but this time
on the boat we're considering, there is an easy way to mount a
through-hull, with easy access to where it should be mounted. This
sort of mounting will keep a wire off the transom, and will prevent
the transducer from being whapped by the trailer bunk if I load the
boat up catawampous, as it were.


I currently have a shoot thru and I'm not impressed with the performance
of the sonar. It could be my installation, but it appears to be by the
book. I tend to lose readings or get inconsistent result when in shallow
water. And in SW Florida, we have ALOT of that.

I've been debating the same thing you are currently discussing. We have
a sort of step in the hull at the transom, plus trim tabs, and it
appears to me the thru-hull the better option. With the unit we have,
while mounted ahead of the step, should always be in clean water.

Looking at the various options for the manufacturer we have, the
low-profile thru-hulls do not include temp, which is something I want to
add if I am going to go thru the process of drilling hold in my hull. I
am hesitant at the one which include temp, but at a cost of an
additional wedge/block extending below the hull line.





Check out the Airmar Tilted Element Transducer. Includes temp. Low profile.
