As long as the transducer makes contact with clean water, there is no
difference between the two systems. The key is to keep the transducer
in the water flow and not where air and foam can interrupt the sonar
signal.

It's really a matter of appearance.

My Ranger has a very odd transom and I don't have a problem with clean
water - even in turns. It's all in how you set it up.

Through glass is never going to be as sensitive and, although it's not
happened to me, can distort the returning echo giving a false depth
reading. Note that it's never happened to me.


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.

If you don't mind me asking, what brand/model of boat are you thinking
about?

I've kinda hinted at it. The new boat will be a Parker 2100 deep vee
center console with a 150 hp four stroke Yamaha. It looks like this:

Here's a view of a "sistership's" console, though I opted for seats
instead of a leaning post:

There's six feet of flat open deck between the seat in front of the
console to the bow. Boat is 8'6" wide. A near-perfect fishing boat for
this area.

What was wrong with the other Parker, or what are the advantages of the
21' Parker vs your 25' Parker?

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.
