RayMarine Element

Airmar advertises their transducers are compatible with RayMarine, here is the rest of the story.

"The Element series (both the -HV and -S) do not support any AirMar transducer offerings and in the Axiom family you have to go to the Pro-RVX to support any AirMar Chirp offerings, but the only transom mounted AirMar chirpo transducer that we support is the TM265LH"

I had a difficult time pulling info concerning the following Raymarine transducer, here is the rest of the story.

"The Element HV (using the HV-100) and Axiom RV platforms  (using the RV-100) both contain a traditional color graph channel we call Sonar that chirps in the high frequency range.  Depending on your depth that sweep will range between 170khz-210khz."

Point is, Humminbird  (Item # 710282-1)  CHIRP Frequencies sweep at: Full: 150-220 kHz, Narrow: 180-240 kHz, Wide: 140-200 kHz. Garmin (010-12405-00) CHIRP High Wide sweeps (150-240 kHz).

I gather it cost more to make transducers that sweep a larger range, and this range allows increased target separation.
