TR-1077A Deep Water Sub-Bottom Profiling Transducer

Model TR-1077A Deep Water Sub-Bottom Profiling Transducer
SPECIFICATION
The MassaSonic™ Model TR-1077A is a high power underwater transducer that operates
in the 3.5 kHz region. The design is based on the Massa TR-1075 Transducer, except it
has been modified to work at depths greater than 20,000 feet. An outline drawing of the
TR-1077A, which weighs 50 lbs. in air, is shown on Page 2. The nominal responses of a
typical TR-1077A is provided in the following curves.
