Wireless Speed Computer

Instruction manual

1. Introduction

The  SPEEDWATCH  wireless  speed  computer 

is  a  highly  accurate  means  to  measure  speed 

through  water  of  any  low-speed  watercraft 

such  as  a  sailboat,  yacht,  kayak  or  small 

powered boats. Designed for the serious racer 

and the advanced users, the SPEEDWATCH gives 

valuable feedback on the performance of your 

watercraft.

The small impeller is placed under the craft, in 

a variety of mounting possibilities. When your 

boat  or  kayak  is  moving  through  the  water, 

the  impeller  rotates  creating  a  magnetic  field 

that  penetrates  through  hull  without  wires. 

This magnetic field is received by the sensitive 

sensor at the end of a cable on the transmitter, 

which is placed within 30 cm from the impeller. 

The transmitter then sends out a low-frequency 

radio signal that is received by the display up to 

5 meters. The signal is processed and displayed 

as instant speed.

The  SPEEDWATCH  uses  this  speed  signal  to 

calculate the instant, balanced, and maximum 

speed as well as the trip and total distance. The 

SPEEDWATCH outperforms any GPS with regards 

to  precise  speed  and  distance  measurement, 

allowing for minute changes in performance to 

be  registered  and  adjusted.  The  SPEEDWATCH 

becomes  an  invaluable  tool  when  sailing  or 

rowing  in  currents,  as  it  measures  true  speed 

through water, rather than average speed over 

land like a GPS.

The  magnetized  impeller  requires  no  power 

source, the transmitter uses a 9V battery, and 

the display includes a long-life Lithium battery, 

good for hundreds of hours of use.
