[CA] Axiom CP370 and Chirp transducer

[CTBob]

Was considering one Axiom E70368 (Axiom 12 MFD w/Navionics+ charts) and one E70369 (Axiom 12 RV w/RV-100 and LighHouse charts). I do not think I have a HS5 Network switch as the only other devices are RMK9, RD424HD Radar, Ray 50 VHF, EV-2 , P70 R, Fusion 750, and Optimus EPS electronic steering. I will a HS5 Network Switch if necessary as having the installation done by a Raymarine dealer. Here is a list of devices I have in addition to the two A125s I will be replacing. CP370, RMK9, RD424HD Dome, Ray 50 VHF, EV-2 with R70 autopilot, Optimus EPS electric power steering and Fusion 750 radio. Boat is 33 center console with twin Yamaha outboards.
Maximum depth fishing is 300 feet. Any advantage to doing one Axiom Pro and one regular Axiom? Thanks for your help.
