Anyone Have This ?

These have been out for a while. There is a little info on THT. I believe they are exactly what I've been looking for, but they are pricey. I would like to here some feedback before I drop the bucks into that hole.

I have a B260 and the cone angle is very tight, 6 degrees on the 50 side and only 12 I think on the 200. I hope someone has some info.

I just installed a 1kw B164 thruhull on my 2520. I've got an E80 Raymarine and this thing is awesome.

I can't get over how it picks up every little detail and I've tested it in 150 feet by sending down a jig and watching it on the scope.

The B164 is dual frequency and has 200 and 50 , with the bottom lock and A scope on the E 80 you can see almost anything.

Drilling a 3 1/2 inch hole in your boat will make you really nervous but it was worth it.

3 1/2"?

IIRC it's 95MM (3-3/4")

3 3/4 is correct. Heart attack either way. Had to get the hole saw from Grainger, nobody else had one.
