Standard Horizon DST521 TM Triducer

DST521

• The DST521 TRIDUCER multisensor is Standard's most-affordable, dual-frequency, 50/200 kHz, transom-mount design. It combines depth, speed, and temperature functions in one housing. Few parts make installation simple, and its compact size is attractive to small-boat owners. Our square-blade paddlewheel has good linearity and is quite accurate throughout the speed range.
