[TG] Transducer for wooden yacht

[Tom - Raymarine - Moderator]

Hello danacaicos,

That's correct, in-hull transducers (sitting in a wet-box/tank inside the hull) will not work in a wooden hull, the timber absorbs too much of the sound energy for reliable operation. In-hull transducers are only suitable for single-skin fibreglass hulls.

For a timber hull you need a bronze through-hull transducer (plastic transducers also aren't suitable in wood because when the timber swells it will crack the transducer.)

There are a range of bronze through-hulls available with different capabilities that are compatible with Axiom 12 RV displays:

• CPT-S bronze tilted-element low-profile Chirp fishfinder/depth transducers or CPT-120 bronze faired Chirp fishfinder/depth + DownVision transducer part A80350, connect via an A80490 adaptor cable
• various bronze CP370-compatible depth-only or depth-speed temperature transducers, connect via A80489 adaptor
• Bronze RV200, RV212 or RV220 single or split-pair RealVision 3D imaging transducers, no adaptor cable required.
  

The simplest and cheapest option are the CPT-S tilted element depth-only transducers, e.g. part A80446, with adaptor A80490.

Tom
