thanks chris, sort of confirms what I suspected anyway. My own fault for being seduced into buying more electronics than I actually need!

might be worth trying the 2 side by side over some known marks to see which gives prettier pictures though!

they will interfere, as ours do, Koden cvs 108, and Garmin 188c, as the transducers are fairly close to each other, however we used to have a Lowrance LMS 350 (lovely set) now deceased, with its transducer near the Koden and they both worked fine, try placing the transducers further apart and try them. Hope this helps.
