[CA] New System

[Ruder]

I also use my electronics for Salmon fishing in Lake Michigan and have upgraded to an Axiom 12RV on my 1990 SeaRay 350 Express. (Same hull as your 370)

My current Transducer setup is as follows:

1) B744V (50/200Hz) connected directly to Axiom using Raymarine Y Cable
2) RV-220 - Raymarine Bronze Realvision through hull transducer pack connected to Axiom using the Y Cable

Here are my observations on Lake Michigan in regards to Salmon Fishing and the functionality of my system.

High Frequency Chirp - I can only access High Frequency Chirp if I disconnect the B744V transducer and the Y cable from the Axiom. My plan, if I liked High Chirp was to add a CP370 DSM for the B744V so that I could retain High Chirp on the Axiom. While High Chirp was slightly better at marking fish than the B744V it will not register my downrigger cannon [censored]. I like being able to see where my downriggers are so have decided that not supporting high chirp is not an issue for me.

Realvision 3D - Love it! Knowing the actual depth of fish and the position to the side of the boat is great. I also love the fact that it saves their GPS position so that when I circle around to the pod of fish i can see them coming on the display and try and drag the boards running the depth of the marks over them.

I have also found that the performance of my B744V interfaced to the Axiom is much better than when it was hooked to my DSM30. I run a 3 window splitscreen with Realvision3D, 200khz and 50 khz.
