Boat depth sounder D110

The D110 Digital DSP depth sounder uses Digital Signal Processing (DSP) to reliably display water depth from 1.2 foot (0.4 Metre) to 1000+ feet (365 Metres). Depth can be displayed in feet, meters or fathoms. Variable display damping is provided so the user can optimize response speed against display stability (averaging). The D110 has programmable shallow, deep and anchor drag alarms built-in and can display the depth in feet, metres or fathoms. A keel offset from -20.0 to +20.0 feet can be entered so the D110 shows the depth below the surface, below the keel or below the transducer. The alarm values and keel offset are automatically converted if the units of measure are changed between feet, meters and fathoms. The D110 uses Digital Signal Processing (DSP) to enable sensitivity never before found in such a low cost sounder like the D110. The DSP also provides superior high speed rejection of false signals due to transducer slap (buffeting), surface turbulence, thermoclines, double bounce and is almost immune to other depth sounders and fishfinders operating near-by. Five levels of backlighting can be selected for night-time viewing. The backlights can be turned ON and OFF remotely. All set-up constants are saved in a non-volatile memory.
