CruzPro D30 DSP Depth Sounder with built-in
alarms

The D30 is a compact digital depth gauge. The D30 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, metres
or fathoms. Variable display damping is provided.
The D30 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 D30 shows the depth
below the surface, below the keel or below the transducer.
The D30 uses Digital Signal Processing (DSP) to
enable sensitivity never before found in such a low cost small sounder. 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 and all set-up constants are saved in a non-volatile memory.
Both through-hull and transom mount transducers are available separately for the
D30.
