I have been working on some tweeking for the Fish Cat#4 . I am thinking of silicone caulking my Eagle 320c transducer to the PVC bottom right behind the seat . I would also make a little battery cmpt. above the water line on the seat back. This is still in the planning stage. Has anyone tried this concept?? I only have concerns with the bottom being of more than one layer of material. My reasoning with using silicone is that I think I can peel it off if it doesn't work out as planned. I would appreciate any input or thoughts anyone might have. Thank you, Illinoisgiller
I have given up on the idea of the transducer locating in the back of the seat. Thanks, especially to Tube Dude for your insight.
I can see my Anchor, he, he, he. What model you got TD?
Not during most of the tube fishing I do, because my jig is seldom in the cone of the 20 degree transducer. But, I have experimented by dropping something straight down next to the transducer rod and you can pick up the jig. It takes some adjustment of the sensitivity though. I usually fish with less than 100%. You don't need 100% but the higher the sensitivity the smaller the objects you can see in deeper water.
Say TD are you able to pick up your jig or lure with your setup like we can ice fishing?
You talking siliconing the transducer right to the bottom of you tube? Risky. What is wrong with a side mount? By mounting it on the side you can put it 1/2" higher than the bottom of your tube (on flat level ground) and it will be perfect in the water, plus less chance to bump it. They don't have to be below the boat.
Theoretically, it will work...shooting through the "hull" of the PVC fabric. Right? From past experience with using the transducer to shoot through ice (and a thin layer of water), it does not produce the same quality display as when shooting through water top to bottom. Anything between the electronics and the bottom will cause interference and potential distortion. Even bubbles caused by normal boat operation will mess up the signal on boat mounted sonar. The area behind the seat is also subjected to a lot of "rock and roll"...making the mount an unstable one from the standpoint of shooting straight down. If the beam keeps moving around...especially over uneven bottom...you will get a wacky signal. The more stable you can keep the 'ducer the better. The only way to tell for sure is to give it a try. By using an easily removeable silicone seal, you will be able to go back to plan A if Plan B does not work out.
