[CA] [CA11] Help me upgrade

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Hardyw,

Q1. Which 9" Axiom MFD do I need if I want to be able to take advantage of all of the capabilities in the future?
A1. An Axiom 9 RV MFD should be considered. If seeking to take the advantage of the greatest number of features supported within the MFD's Chart application, then a Navionics or C-Map chart card would be recommended for use with the system. Please note that any chart card which is presently used with your e7D may instead be used with the Axiom MFD.

Q2. I believe the Axiom will work with my E66088 transducer with a certain adapter cord?
A2. Yes. The A80488 Adapter Cable may be used to adapt the E66088 B60 transducer alone to the Axiom MFD to support the same type of fishfinder features which you presently have with your e7D MFD. If simultaneously installing a RV transducer(s), then the A80491 Y-Cable may be used to interface both a RV transducer(s) and your B60 to the system.

Q3. When I am ready to fully upgrade transducer which one will I need? My current transducer is located midway down on the starboard side, approx 12 degree deadrise.
A3. If seeking a thru hull transducer (for best performance), a T70318 RV-212 Bronze Through Hull Transducer Pack would be recommended.

Q4. If I am currently not able to hold bottom very well at tuna trolling speeds in approx 200 ft of water do I need to upgrade to a 1000kw transducer instead of a 600?
A4. Low power / high frequency CHIRP sonar, DownVision, and RealVision sonar supported by the RV transducer pair should be able to support operation in this depth. Please click here to view a FAQ addressing this subject. Many will opt to additional install the B60 transducer outboard of the RV transducers to additionally support 50kHz/200kHz sonar imaging and support bottom tracking at higher speeds than may be supported by the RV transducers.
