[CA] [CA11] Axiom 7 transducer issues

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Greg,

General comments:

- ensure that the MFD has been updated with LightHouse 3 v3.11.42 or later software, as improvements were made to sonar processing

- should imaging issues persist, attach screen snapshots and/or video showing the sonar performance when operating around structure. Be certain to overlay the Fishfinder application's screen with SOG prior to taking any such screen snapshots or video.

- attach photos of the transducer installation location, particularly with respect to hull features (chines, strakes), trim tabs, and outboard / outdrive / prop, as well as with respect to the bottom of the hull. Additionally attach photos of the hulls bottom and indicate whether it features any steps.

Q1. will my axiom 7 unit work with a different transducer, like the real vision RV transducer, or are the axiom 7 units themselves configured for EITHER downvision OR Realvision.side vision?
A1. Unfortunately, the sonar circuity within Axiom 7 DV MFDs is exclusively designed to produce DownVision and low power / high frequency CHIRP conical sonar imaging. RealVision and SideVision sonar imaging may be added to the system by interfacing the Axiom 7 DV MFD to either another MFD having internal RV sonar circuitry (ex. Axiom RV MFD or Axiom Pro RVX MFD) or to a RVX1000 RealVision Sounder Module, which in turn has been interfaced to a RV transducer.

Q2. is my current unit and transducer capable of what I'm hoping for?
A2. Negative. The A80351 CPT-100 DVS - DownVision Transducer is exclusively designed to support DownVision and low power / high frequency CHIRP conical sonar imaging.

Q3. how can I make this unit do what I'd like it to do - seeing details, knowing what I'm on and where I'm on it etc. what are my options?
A3. See comments and response to Q1.
