SDD-110 Saltwater Depth Indicator w/Low Profile Lexan Thru-Hull

Sdd-110 seawater depth indicator w/low-profile lexan thru-hull transducer. The sdd-110 operates on working frequency of 120khz, so it won't 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. Because the sdd-110 is a one-piece system, it doesn't 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. 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. The sdd-110 also features nmea-0183 depth data output that can be interfaced with other onboard equipment. Similar to si-tex's 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.
