Seiwa Black Box Fishfinder

NEW ! Turn your Seiwa Chartplotter into a fully featured Colour Fishfinder with the simple addition of the Black Box Fishfinder module & a transducer. Choose from either the 170kHz single frequency module or the 50/200kHz dual frequency module.

With the versatile Black Box Fishfinder you can have Full Screen Fishfinder, Split Screen Fishfinder & Chartplotter or still use Full Screen Chartplotter. Fish & bottom echoes are displayed in real time & range, gain, frequency & shift are all automatic.

The sophisticated image processing circuit features interference rejection, a noise filter & a STC function to reduce/eliminate surface clutter, resulting in a superb clear picture providing you accurate information of what is below your boat.

The "White Line" facility also helps you distinguish between fish & the seabed when fish are close to the bottom. Any part of the echo image can be magnified by x2 or x4 or by any user selected range.
