The 1" transducer used on the Super Thirty II emits a 32 degress cone angle. This wider beam is used in shallow water since it provides a wider area of coverage.
NOTE: While the 1" transducer is recommended for the Super 3011, some may prefer the performance of the 2" transducer. Either will work and it may be a matter of personal preference as to which one is used.
