Axiom/RV-100 installation

Welcome to the Raymarine Forum JPA,

Initial comment: the photos which you have referred to have not been attached to this thread. Please try again and ensure that the photos have been re-sized to not exceed 500MB.

Q1: Can you recommend any position changes that might have a reasonable chance of improving RV-100 performance at higher speeds?

I am primarily a coastal striped bass fisherman but I occasionally venture offshore in search of bottom fish, sharks or school tuna, I have little experience with Chirp but it seems clear that I will need to keep the B-60 to maintain consistent bottom tracking at higher speeds. I had not realized that the the Axiom/Y-cable set up eliminates High Chirp, so for the time being, my DS500x remains installed and the Y-cable, B-60 connector and RV-100 connector remain above deck. I would like to clean this up a bit but overall performance is more important so I have a couple of questions that may help me decide how to proceed.

A1. Please see my initial comment regarding photos. That said, the RV-100 is designed to support operation at speeds that are typically fished. While some may find that the transducer is able to hold bottom at low planing speeds, results will vary. For this reason, Raymarine offers a Y-Cable which may be used to permit the Axiom MFD to simultaneously be interfaced to both the RV-100 and to your B60.
If supplied with the product ID printed on your transducer's tag, then it will be possible to specify which Y-Cable to order. With hull such as yours, the Axiom MFD would be configured to display 50kHz or 200kHz fishfinder channel when operating at speeds that would not be supported by the RV-100.

Q2: Is the Axiom RV significantly better at processing and displaying 50/200MHz data than the DS500x?

A2: Improvements have indeed been made to the 50kHz/200kHz fishfinder processing since the introduction of the DS500X. That said, they are subtle. If seeking to eliminate a display, then it would be recommended that the aforementioned Y-Cable be obtained to permit the Axiom MFD to additionally be interfaced to the B60.

Q3: Would High Chirp significantly outperform 50/200MHz at lower speeds.

A3: Yes. High CHIRP excels in identifying organics which are suspended within the water column.

Q4. It’s not in my budget anytime soon but if I were to connect the B-60 to a properly networked second Axiom RV or DV MFD, would I be able to view both 50/200MHz and High Chirp?

A4. Should the aforementioned Y-Cable be installed, then HIGH CHIRP would not be available to the system. However, should a second Axiom RV MFD or DV MFD or CP370 be interfaced to the B60 and to the currently installed Axiom RV MFD, then you would have access to 50kHz/200kHz as well as to High CHIRP.

Q5. Is there a setting that would allow me to view attachments?

A5. See my initial comments regarding your attachments.
