Anybody else have issues with their suction cup that holds the transducer not staying put? It seems like several times during the day mine loses its grip on my boat. Not a huge deal but a slight annoyance. Perhaps a slight coating of product "x" on the rubber suction cup will make a difference.

I suppose an email to lowrance might be in order but there are lots of smart people here on QJ so...........any thoughts :question  

1) Remove the suction cup.
2) Run the transducer line along whichever side you mount the head.
3) Fasten line to thwarts, bow seat with zip ties.
4) Run line all the way forward to bow bulkhead and use silicone caulk to make a 'puddle', making sure you have no air bubbles.
5) Imbed transducer in caulk, and let cure for a day or two, before moving canoe.
6) Carefully portage canoe to nearest body of water for a test paddle. (If you live farther from a body of water than I do, you may want to load it up and drive.)

This is a 'permanent' mount that can be removed by cutting the silicone (harder than it sounds).

OS
are you shooting through the boat?

Through the hull exactly as O_S described is wonderful. No fuss, no muss and no annoying gurgle at cruising speed.

Or a Vaseline® type concoction that doesn't eat rubber. Gurgle gurgle.

I do the latter, solved the issue....and I can tell exactly where is was for the next time; ah but is an oxidation issue. If you buy two red sports cars that changes everything. I have also shot through the hull, I used the acoustic epoxy; the Silicon Caulk is a good idea, thats easier to cut than the epoxy ;)

Goodnight! What have I been missing. I suppose a guy could use pressure sensitive tape to aid with the line along with the cable ties. No more storing it for portages, no more gurgle, no more knowing it is slowing you down, no more coming undone..........
:-*  :-*  :-*

I never really considered it was slow me down, rather that it was speeding me up to catching the fish that I was fishing to, the culinary delight that I was seeking, and then there are the photo opps too.

I wonder if there would be any difference in shooting through carbon fiber vs. kevlar?

Not as long as you use small caliber rounds. ;D ;D

I'm a "thru-the-hull" shooter.  

Many years ago, I took a short section of plastic down spout and trimmed it to the interior hull contour just behind the bulkhead in the bow of my canoe.  I then siliconed the edges to make a water-tight "cup."  I drop the transducer in the cup, pick up the small  section of synthetic sponge I cut down to fit the cup, dunk it in the water and add the water to the cup.  I then stuff the sponge in the cup to help anchor it in place ... its a bit over-sized so it provides a bit of friction so the transducer will stay in place even when the canoe is inverted.  I don't usually portage with it this way, but under most circumstances it will stay put for a moderate length portage.  I already have hull clips in place under each gunwale for mounting a rod tip protector tube (aka golf club sleeve), so I just run the cable thru the clips from the mounting thwart to the bow.  (I added one more clip on the bulkhead so the last mount is very close to the transducer, so even if it falls out of the cup, it doesn't fall below the gunwale line when the canoe is inverted.)

Somehow I missed this one. Very funny OS. I have a hunch things wouldn't get dull with you around  ;).

I suppose I will just have to try it to really know but I'm still wondering if anyone has tried through the hull with a kev/carbon fiber boat?

Try one post back, for example. ::)

OK, wasn't sure what everyone paddles. Thanks.

North in a few weeks. Boats up there....... maybe I'll have time to test it out. [smiley=thumbup.gif]

The big question becomes..............glop of glue or cup of water?

I wonder if going through the hull reduces the longevity of the batteries. In other words, when the batteries start to get weak would they then prove ineffectual because of having the additional material to signal through?

This is not my forte'. So if I seem ignorant of the basic fundamentals of electronics it's because I am. I am willing and eager to learn though ;).

Glue if you want the mount to be semipermanent. Water if not.
