The SL172 will tell you

The Signet Marine SL172 is a sailboat depth sounder which features advanced algorithms that automatically compensate for boundary thermal layers, multiple echos, listing, hull turbulence and varying bottom conditions. Advanced microprocessor logic, along with time-proven transducer design provide sensitivity to bottom contour variations as small as one-tenth of a foot under normal operating conditions.

The SL172 Depth Sounder consists of two major components: The instrument display, which contains the electronics, alarm, and Liquid Crystal Display (LCD), and the depth transducer. The transducer is available in flush, mushroom, extractable, or brass configurations.

For greater peace-of-mind, the SL172 was designed with a forward-trending alarm. This alarm sounds up to twenty seconds before you reach a preset alarm depth by calculating a trend in decreasing depth readings. The Signet Marine SL172 Depth sounder offers affordability and security in one convenient package.

Each unit is vigorously tested and must pass extensive quality control standards before it is shipped. All units come with a two-year warranty.
