es78 and the Airmar B744V transducer

[Chuck - Raymarine - Moderator]

TexasPilot71,

Q1. ... you mention the existing transducer can be mated to an eSx8 MFD with the adapter. I presume you mean eSx8 (which would be the MFD I'm interested in), correct?
A1. No. My prior response indicated that the B744V cannot be mated to the TRANSDUCER socket to an eSx8 MFD and will not not support the MFD's CHIRP/DownVision fishfinding sonar circuitry/features. As indicated within my initial response, the B744V may remain interfaced to the DSM30/300, which in turn may be interfaced to an a/c/e/eS-Series MFD or HS5 RayNet Network Switch via the previously specified cable assembly.

Q2. I don't think there is an eSx7 MFD line of products.
A2. Partially correct. While Raymarine offer 9" and 12" eSx7 MFDs (i.e eS97 and eS127), Raymarine does not offer a 7" eSx7 MFD. Unless you are seeking to add CHIRP (conical) fishfinder sonar and/or DownVision fishfinder sonar features to the system, then you may save yourself some money by purchasing and eS75 MFD (has no internal fishfinding circuitry) and then interfacing the DSM30/300 to the MFD via the previously specified cable assembly.

Q3. If so, and if I go this route, you're saying that I can remove the bulky DSM30/300 from the system with the addition of the adapter, correct?
A3. Unless a 9" and 12" eSx7 MFDs (i.e eS97 and eS127) will be installed instead of a 7" eS-Series MFD, then this is not correct. Raymarine does not offer a 7" eSx7 MFD.
