transducer

[steveagnew]

ahoy! I purchased a Lowrance HDS7 chartplotter/fishfinder at the Defender sale. I'm getting baffled at which transducer to get for it and the best place to install it. I removed the old (original) one which was on the centerline thru 3" of fiberglass directly below the v-berth insert. Any suggestions?

Hi steve, and welcome to the forum!

I think I would choose an epoxy-to-the-inside-of-the-hull puck transducer if possible. It looks like they have one for your unit:

PDRT-WBL Part #106-89 $64.95
Shoot-thru-hull mount, 20 degree pod type with remote temperature (200 kHz). (20 ft cable)

I don't know about Lowrance, but if I remember correctly Humminbird had a program where you could trade the transducer that came with the unit for another style, just by calling them and making arrangements.

You can put the puck in a zip-loc bag of water and make some trial placements to see where it works best before you epoxy it in place. Just ahead of the ballast is a good place to try.

Then I would glass the other transducer hole closed. (Not that there is necessarily anything wrong with a properly done hole in the boat.)

Again, welcome :)

thanks for the reply Rachel, I have a Hawk-eye that I glued in after i thought i had the "spot", intermittent results;off when you really wanted to know. I chiseled it loose and searched again and built a water box w/ 4" pvc pipe low in the hanging locker; not much better. I'm hoping thru
-hull will be more reliable. But, which one and where?

[Figment]

As far as "where".... the old one was there for a reason. The wineglass shape of the hull doesn't offer many (any) convenient spots for such things. Mine is in the same spot, and that was not my first choice either due to the degree of hull modification required.

I'll second the suggestion to talk to Lowrance about the "what", but be prepared to hear that they don't have anything with the very long stem you'll need to use that location. There is a company out there that makes fantastic transducers for all sorts of funky applications... the name will come to me I'm sure, right after you buy one.

Airmar?

[earlylight]

Airmar is one of the largest manufacturers of transducers. They manufacture transducers fior Sitex/Koden, Garmin, Raymarine, Furuno, Lowrance and Humminbird to name a few. Check their website and good luck.

I had success with a Humminbird puck style transducer mounted under the starboard setee on my Triton- no thru-hull needed.

[Figment]

Yes, Airmar. Duh.

Even if you don't see what you need on their website, pick up the phone. Absolutely stellar people.

Thanks to all. After several phone calls, I decided to order Airmar's P319. Some surgery will be required , but I will install it in the location of the original one
