Thru Hull Transducer

[Manomet]

Guys,

As always, thanks for all the insight and support. You have made buying and using my 210 CC a jpy.

Now, I am (already) considering trading up to the 235CC butI have a couple of questions in relation to fishfinder transducers. One of the questions is for the factory and the other is for the group.

1. (For the factory) Is it possible to mount a through hull transducer on the 235 and is there a specific spot where it can be mounted for reliable performance.

2. (For the group). On my current boat the fishfinder is useful only at low speeds and it shows much noise at speed. I have been told that this is due to the airflow and turbulance under the boat. I have also been told that a through hull transducer would solve this if mounted in the right place, allowing me to better see the bottom, structure and fish when travelling at speed. Can anyone give me an expert opinion about this (true, false, gotchas, etc) and also any recommendations as to brand, etc?

Thanks again...

Ted

Manomet,
1. I don't think you can mount a through hull transducer on any Triumph boat.
2. I've had two Triumphs and received great performance of my fishfinders on both even at WOT. I had one Lowrance and 2 Garmin. The 2 Garmin units have both been combo GPS/Sounder. The noise you have could come from several sources. The main one being placement of your transducer.Most of the time I've found that the transducer is either too low or too high on the transom. You need to experiment with moving it up or down and see if the noise clears up. Look at the transducer when you're on plane. If its kicking up a lot of spray its probably too low in the water.Most Fishfinders have a noise adjustment from low to high. I'm sure you've set yours correctly. If you have not read the manual for your FF,make sure you do.You may pick up a few tips to solve your problem.You are correct in the fact that you will have problems if you have turbulance, but just make sure you do not place your transducer behind your baitwell pick up. Good Luck.

From the factory:

We do not recommend through hull transducers on any of our boats.

I would say it is possible but not desireable to mount a through-hull transducer in a Triumph. I am pretty sure with some careful engineering one could design a mounting configuration similar to my high-speed water pickup that the factory would OK. However, being as our boats are almost always trailered, there is a huge risk to damfaging a through-hull mounted transducer.

As far as brands go, almost every electronics manufacturer will use the same brand transducer, so pick the electronics you like the best. Lowrance and Furuno have the best Fishfinders, Garmin and Raymarine are tops in GPS technology, and Furuno has the best Radar. Humminbird and Interphase make excellent Specialty Sonar products as well.

And in regards to the noise issue. It is true a properly installed through-Hull transducer can give the best depth reading, however, it is far more difficult to properly install a through-hull transducer than a transom-mount one.

Hope this Helps.

For 20+ years i cursed those kayakers on the river,but now i are one ON ALL THE MESSAGE BOARDS AND FISHING FORUMS ON THE SITES I VISIT, THE ROTOMOLD GUYS ARE GLUING A CROSS SECTION OF A LARGE SWIMMING NOODLE AND BED THE TRANSDUCER IN VASELINE AND IT PICKS UP THRU THE PLASTIC. OUR BOATS ARE CONSIDERABLY THICKER BUT I AM GONNA TRY IT WITH THE RAYMARINE I AM TAKING OFF THE 210CC AND INSTALLING ON MY YAK

The transducer would pick up throught the hull of a plastic kayak, although with worse degradation of signal due to PE being denser than most FRP, because PE kayaks are a single hull. However, the Triumph hull has a considerable amount of air-trapping flotation foam that would interrupt a transducer beam. In order to mount a transducer in the hull of a Triumph, one would have to either find a spot where the inner and outer hulls were bonded directly together and was large enough to properly mount the in-hull mounting flange, or mount the transducer through the hull of the boat, which brings us back to the warranty issue among other things. Hope this helps

Thanks guys, I appreciate the info...

manonet have you tryed lowering the gain ajustment on your fishfinder it will get rid of the noise do it a little bit at a time untill it clears up. i have to put mine less than 50% i have a garmin and it works well took me some time to learn how to use it right.. at frist it was showing fish everwhere and i could not catch any of them.i had to read the manuel good and play with it ....befor i got the hang of it.... hope this helps
