Looking for advice on the best location to mount the XM 9 20 MSI T transducer on a Stratos 186 VLO.
Based on answers to similar posts, I suspect that I'll have to add a Thru Hull XP 9 20 transducer via an MS SI DB Y cable to get depth readings at speed, but wanted your opinions first.
Also, since the Helix is a CHIRP model, if I do have to add the XP 9 20 Thru Hull, will I have to switch between transducers via the Menu to see depth at speed via the XP 9 20, versus CHIRP etc. from the XM 9 20 MSI T that comes with the Helix?
I've added pics of my transom (I hope!), and any advice would be most welcome.
