I do see the need for it to be on the trolling motor for bass fishing ! And if you are chasing big roaming fish like the guys do in the crappie tournaments that’s where it needs to be . But if you fish brush piles in open rivers and lakes with current going one way and the wind going another trying to use spot lock and staying on the fish with the transducer on the TM it’s useless ! Absolutely love my fishing specialities pole so easy to move from side to side or just lay on the deck!
