transducer removal?

This is exactly what I need to know!!!!


Do you have to put water under the transducer?  I haven't put mine in yet cause I don't want to screw it up if i just goop it down!!!!!     

Hope this helps!

Ok !! So no GOOP on the transducer?  Oh sorry for the thread HYJACK!!!

You can also use a jumbo pool noodle for the foam. It's a lot cheaper, about $1, and the leftovers have tons of other uses.

Boy, am I dumb. What is the water for? Doesn't it evaporate?

 I gooped mine down on my first kayak and it worked great. I thought about using the pool noodle idea the second time, but goop worked well the first time around (and it came off with out a problem) so I just used goop when I put it on my new kayak.

An air gap will distort the transducer signal, so water is used to maintain a medium of similar density (water->poly->water) which won't distort the signal.

Your not dumb, you just have not done it before

As Allen said, it completes the couple between the transducer and the hull. I actually just started using this method and I really like it! Previously I was just putting it in dry jambed against the hull with pool noodle (and that actually works just fine), but the Malibu Exteeme I've been paddling had a small tupperware cup with the bottom cut out glued to the hull by the previous owner. I added some water and jambed my pool noodle encased transducer into it and it works great! The pool noodle jams against the side of the little tub and holds it down just fine and the added water just completes the "circuit" so to speak. (To answer your question about where the water goes, you just replace it each time you go out and dump it when your done.)  Previous to using the dry jamb, I originated the use of goop to stick down transducers in poly boats :insert bigazz cheese eating grin: That works great too, but I really like the mobility of the noodle bowl and the noodle jam.
 I'm sure all of these methods eat some sensitivity compared to hanging it over the side of the boat into the water, but not enough to count. Hmmm, think I'll run some trials when I get back to FL to see if the dry jamb reads any different from the wet jamb and I guess I could goop one more down for the team.

That's some funny stuff there Wali!  Who's writting your material?   

Spot, fishfromtupperware, et al. Thanks for the information. I'm going to mount mine wet per the example by Spot. It's going into my Scupper Pro.

What kind of Goop is everyone using to begin with?  I'm trying to set up my yak and I like the pool noodle method mentioned on this site but I'm not sure if I've been looking at the wrong thing.  I found Goop Marine adhesive at my local West Marine but the packaging says it is not recommended for use with polyethylene. 

Sorry for the newbie question and confusion. 

Marine Goop is what most use.

Yeah, even though Marine Goop says that, that's what I use for almost everything including my transducer. Depending on where you use it, it may start to peel off after a few years, but for the most part, that stuff is great.

I've used nothing but Marine Goop with no problems. I've heard that all of the various packaging (automotive goop, home goop, etc) are basically the same thing.

Thanks everyone.  Still have the newbie fears about cutting, drilling, etc even though I'm anxious to get the yak rigged up.
