Hi all i fish for dermersals from 10-70 mtrs iam looking for advice on the best transducer for my tzt2 preferably through hull mainly looking close to the bottom i currently run 6m bottom lock and range shift to show last 15 mtrs with my p66, can i possibly get a tranny with a wide beam that will show high definition on the seabed, i know narrow cone angles show better definition but lack the coverage of a wide beam is there a compromise ?? and happy to use high frequency only as i don't fish deep but need something that will also pick up bottom hardness .
