I am currently using a pair of older Humminbird 997c side imaging units that work OK but not great. I have them setup/installed correctly but the side imaging resolution just isn't that great. I have considered adding a 93sv plus to the bow to eventually use for livescope/panoptix but if these units will have better DI and SI than my old birds than I may as well just buy two and replace both my birds.
For the unit at the console, can I run a thru hull transducer and a transom transducer and connect them with a Y cable to get on plane depth readings? Does anyone with experience with Humminbird 997 or similar units have an unbiased opinion on if switching to two 93sv plus units would be a wise choice?
