I want to upgrade my electronics. I get really confused on how to set the unit up with all the options, can somebody give me a brief history of the Garmin transducer (not super technical) including the conflict with Lowrance. I've seen reference to a GT50 For example. Also if I buy the Black Friday deal on the 93 UHd with the transducer will it be able to give me 2d depth up to 35 mph or do I need another dedicated 2d like Hummingbird. I am upgrading from a Lowrance HDS touch gen 2 and hope to improve on the dsi and 2d and of course add good side imaging.
Thanks in advance for your input!
