p strong SDD-110 Seawater Depth Indicator - Display Only strong p p The SDD-110 operates on working frequency of 120kHz so it wont interfere with other onboard echosounders This compact unit - measuring only 4 3 X 4 3 X 3 5 - uses Digital Signal Processing DSP technology to deliver accurate digital depth readings from 1 5 to 1 375 in easy-to-read numerals The large four-digit LCD display offers five levels of backlighting for optimum visibility in all ambient light conditions p p Because the SDD-110 is a one-piece system it doesnt require a black-box sounder or the complicated wiring associated with network sounders Instead the 120kHz transducer plugs directly into the back of the unit for fast and easy installation The SDD-110 uses an inexpensive flush-mount 2 thru-hull transducer with a 38-degree beam angle This allows for easy installation and proper beam orientation on most hulls without the need for a fairing block p p In addition to providing precise water depth data the SDD-110 also features a visible trend indicator to indicate if depth is increasing or decreasing Audible alarms also alert the operator to dangerous shallowing conditions or if the water drops below a selected depth - useful for fishing p p The SDD-110 also features NMEA-0183 depth data output that can be interfaced with other onboard equipment Similar to SI-TEXs popular SST-110 temp gauge the SDD-110 is a drop-in replacement for the venerable Datamarine Offshore Digital Sounder popular for many years on numerous sportfishing vessels and workboats p --- cis2 mmxtmJVt --- br
