Wet mount transducer alternative mediums used?

Postby AshG » Wed Jul 13, 2016 10:54 pm

I just use water in mine with no dramas, but out of interest, what else can be used or do you use that's not water?

For a wet mount why wouldn't anyone use the medium that is all around you so that you dont have to worry about leakage or topping up. After all they are designed for water.

...because I'm installing a wet mount where there's the possibility of it causing corrosion over the long term (alloy creek boat) and it will be in direct sunlight so algea growth could be a problem. Anyone here using glycerine?

I guess a way around algea and corrosion could be distilled water, and using a blacked out container that stops sunlight...

You going to shoot through an alloy hull?

You could try some cheap cooking oil. You want something inert that wont get bubbles.

Dont know if you could test signal by putting in a plastic bag of water and sit on bottom of hull to see what signal is like through alloy. If there is no air between bottom of boat and bottom of bag should work.

I was concerned about it as well and was just going to put a bit of water in the hull and test it that way, googling brought up mixed results saying it doesnt work and others saying it does. Had a reply from a reputable bloke over on the Ausfish fishing forum and he said he has installed many sounders as shoot through in aluminium hulls, and said it works perfectly each install. Will do a test though before final fitting.

If you are worried about alge put a bit bleach in the water.
I have heard of guys heating up vaso and poring that in.

Think I'll just use a blacked out container, have more of a choice as I'm not limited to space like in the kayak

I once had a wet mount setup that wasn't all that well glued in and water leaked out under the sides of the foam mount so as an alternative (till I ditched it completely) was a blob of hair gel that did the trick :lol:

how about K-Y gel which is often used in ultrasound body checking? It should work for sonar as well.

Good to hear, is the container sealed to the hull or just sitting in position?

I can think of better uses for KY :lek:

I’ve done it in my tinny. However, the signal was degraded. It shot through no worries and certainly worked but the picture was clearer and stronger when I moved it outside the hull. I did it originally to protect the transducer on a boat I beat about a bit. But I soon moved it back out and just got used to reaching over the side and pushing it back down when it takes a bump. I wouldn’t do it again.
