Hello there! I recently bought a boat with a onyx10si with 360 imaging mounted to the front of my boat . My question is , I would like to get another graph for my console and link them together? My understanding is I can only do this with another onyx? I really just want SI and DI at my console, so can I just by an onyx with just a sonar and use the SI and DI from the front unit? Or fo I have to buy a separate onyx with SI and DI? Don’t know much about electronics, so any help would be greatly appreciated!! Thx Ben
