Hi guys, new to nicer fish finders here. I picked up a echomap chirp 94sv with the Lakeview card and need a transducer. I found a GT52 and a GT50m for the same price. I'm wondering which one to get. I read the post below here about the disappointment of the GT52 but I also fish shallow water lakes under 50 ft in the midwest and don't know if the GT50 would be more for deeper water. The guy at Garmin didn't seem to give me a great answer as he said both are fine.

Thanks
