Design a display unit for speed transducer!

How could i measure the speed of a boat with speed transducer from "navman" without using its display unit?
I want to create the display unit myself.
Anyone know the method meausre the speed through speed transducer's paddle wheel. Please tell me.

In general most speed sensors send out square wave pulses. Industrial electronic suppliers sell the pretty little LED counters. About $ 150 up. Omron Corp. is a good brand.

Omega Corp has a a set of catalogues available that tell you (that is SELL you) what parts you'll need, and also how to build it. The catalogues were free last time I checked. http://www.omega.com/
