The Si-Tex SDD-110 Seawater Depth Indicator Display operates on working frequency of 120kHz so it won't interfere with other onboard echo sounders. 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 1375' 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° 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.

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 Datamarine Offshore Digital Sounder popular for many years on numerous sportfishing vessels and workboats.
