FI-70 INSTRUMENTS - DST-800 DEPTH/SPEED/TEMPERATURE SENSOR
The DST800 is a thru-hull smart triducer multisensor that reads depth, temperature and speed. The digital signal processing inside the plastic housing provides data straight to your NMEA 2000 network and the three sensors in one means that you only need to make one hole in your boats hull which is a bonus for boat owners and boat builders. Because of the wide fan-shaped beam, the DST800 is able to find the bottom even when installed on high-deadrise hulls or on sailboats when heeled.
The 100W transducer can read depths up to 330ft, operates on a frequency of 235 kHz and has a beamwidth of 10x44 degrees.
