I have a 73sv on the console of my boat and a 73dv on the trolling motor. I like both units. I use the 73dv for ice fishing and it works good using the gt-8 ice transducer. I've had them for about 3 years. Bigger screen then the elite-5 I was using. This year I picked up the Panoptix PS22 transducer to try on the ice. Now I'm just waiting for ice.
