HELP, what to do about transducer? Lowrance
I need some guidance about buying a new transducer. I’m sure my friends at IFish can help with the decision. First of all, what type of transducer do you have?
-shoot thru/in hull
I have a Lowrance LCX18C finder that needs a new transducer. I have the 600W transom mount that has been replaced once before. I’m considering purchasing a 600W bronze thru hull, but that would require another hole in my hull below the waterline. The transducer itself is about 3” x 5” an I would have to install a fairing block too to compensate for the deadrise (deep V). The fairing block is about 5” x 12” and would extend roughly 1.5” down. Some websites state I may lose 1-2 knots because of this. I have a 28’ foot deep-vee with a 454 MPI Bravo 3 and have adequate power, not an overabundance. This transducer set up is $150, not sure if the “high speed” fairing block is included. The idea is the thru hull would give me better performance at higher speed especially looking for schools of longfins or bottom fishing. . Right now, my sonar is worthless at any planing speed due to turbulence.
So I did a little research and found out Airmar Technology makes most, if not all, of the transducers for all sonar manufacturers. They make an angled "B164" 1000W thru hull which would not require a fairing block. The product brochure even says it can be interfaced with any sonar unit. The best part is the installation would be a breeze since I have a Hummingbird depth sounder that the OEM installed. It’s transducer is 2” like the B164. It’s cute, but not all that helpful. The big issue is the B164 price, $600-$800. I haven’t researched the price too much, but getting a higher powered transducer would undoubtedly help with target discrimination at depth.
I’m looking for some thoughts on what I should do? I originally thought the fishfinder unit dictated how much power went to the transducer, but it’s the transducer that determines that. If you have either type of thru hull transducer, I’d love to hear about your experiences. It seems either thru hull will work better that what I have. I love my Lowrance when it works properly, but the transom mount transducer is not the way to go on my application. Maybe the B164 will let me look for fish at 15-20 knots instead of a troll speed.
