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.
