sonar transducer TE 31

[pallares]

does anybody know if the sonar transducer for a TE31 needs to be a 12 or 20 degree offset or flat? i'm trying to put a new chirp ducer from raymarine and attach it to a C97
thanx fp

Your best bet is to measure where you want to put the transducer to decide. Since the ange is variable on the 31 as it is on the majority of boats, the location of the transducer will define which one you need.

These angle finders are inexpensive and quite accurate
