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.
