[CA] [CA11] Best transducer for Axiom Pro 16 RVX

[Bobjamieson]

Have Axiom Pro 16 RVX with RV220 transducers and Quantum 2 Q24D radar on 38’ Bertram. Used in Pacific Northwest for salmon fishing down to 200’ halibut fishing to 250’ and prawning to 400’. There is often a very distinct thermocline anywhere from 40’ to 80’, at present sounder does not work well 200’. It loses bottom and if it has bottom line on sounder it does not show up as digital depth reading on chart plotter. What additional transducer do you recommend and do I need a cp370 or cp470 with that to get best reading or is the unit by itself sufficient?
