[CA] [CA11] Axiom Pro RVX - High / Low chirp Transducers??

[Chuck - Raymarine - Moderator]

Welcome back to the Raymarine Forum DFMott,

As you have suggested in an earlier message, the RV transducers are primarily designed to support the needs of nearshore and inshore fishing. When fishing offshore waters, 1kW 50kHz/200kHz or 1kW/2kW CHIRP fishfinder sonar is typically recommended. The primary advantage of an external fishfinder sounder module is that its sole function is to process analog fishfinder transducer signals. As such external sounder modules do not have additional circuitry (ex. displays, WiFi, etc.) which can be a source of signal noise which can adversely affect fishfinder performance. Typically, external fishfinder sonar modules will provide the greatest level of fishfinding performance (depth and image quality) over a MFD's internal fishfinder circuitry. Anecdotal feedback has supported the information supplied above. How deep is the water which will be fished?
