Degree of Tilt for Thru-Hull transducer?

[John3325]

Good evening all,

Ordering a new electronics package for my 23 Seacraft IB. I am going with the Garmin 741xs or 742xs, and will be getting the B150 thru-hull with it.

Question is, what degree and what location should I be getting and doing? The transducer comes in 0, 12, and 20 degree configurations. The thru-hull will likely be located in the bilge where accessible towards the inside of the boat, so I think that means I would want the 20 degree configuration?

Any help is greatly appreciated!

I have the b-164 at 20 degrees

Don is spot on! Go with the 742

Thanks guys,

I am leaning towards the 742xs. I thought I'd need the 20 degrees thanks for the confirmation.

Does anyone have any experience with the GT23M-TH? This is the fairing block style thru-hull which also gives you the ClearVu (aka DownVu) sonar scanning.

Is it worth the extra $200 or so get the down scanning capabilities? Instead of just have the one hole with the "mushroom" style thru-hull, you now have to deal with the fairing block so is it worth it?

I found this thread over on THT outlining the difference, but do you gain much more than just having the regular sonar?: https://www.thehulltruth.com/marine-...nvu-chirp.html

I'm looking to install the Garmin 7610 XSV / 7612 XSV with airmar B75 thru hull 20 degree tilted element with chirp.

I would go with the B175H or M depending on how deep you fish. Much better transducer

So slight curveball today, Semperfishing over on THT had an early blackfriday sale on Garmin 840xs for $465. I ended up ordering one of those.

For that price, I'll take the larger screen and I don't mind the buttons.
