with accuracy you can count on.
If you race sailboats, the benefits of an accurate speedometer
are probably already fairly obvious to you. Even still, you might
not sail with a speedo because you cant be bothered to drill
holes in your hull and wire-up a paddlewheel transducer.
Or maybe you already have a through-hull speedo but youre
sick of the transducer getting fouled and youre never quite
sure if the instrument is properly calibrated.
The award winning SpeedPuck is completely self contained and can
be installed in seconds, without tools. Instead of using a paddlewheel,
the SpeedPuck calculates your speed by measuring the Doppler shift
in GPS signals to provide you with an updated reading every half-second.
The SpeedPuck never needs to be calibrated and maintains uniform
accuracy at all speeds.
See what you can't feel.
A less than half-knot change in boatspeed doesnt sound like
much. It doesnt feel like much either and thats the
Unless you have an accurate instrument like the SpeedPuck on board
you probably wont notice anything at first. Eventually you
will notice though because even if youre only 0.1 knots off
pace, youre losing more than a boatlength every three minutes.
Without a good speedo, youll most likely be sucking exhaust
by the time you realize that somethings wrong.
With the SpeedPuck you get a new speed measurement every half-second.
If you wander into adverse current or your crew on the rail start
slacking, the SpeedPuck will tell you right away.
||Hit the water. Now.
What do you do when you read these words: Please read this
manual fully before using your new... ? If youre like
most sailors you probably stop reading and immediately stash the
document in an obscure location where it will suffer water damage
and / or never be found again.
With the SpeedPuck we decided to get real and design a product
that almost anybody can figure out and start using in a few minutes,
without having to read anything.
|Easy to Read.
The SpeedPucks sunlight-readable high-contrast LCD screen
features 27mm (1.1) tall digits in a font thats optimized
for readability. This means that if your boats under 40ft
long youll be able to mount the SpeedPuck on your mast and
read it easily from anywhere in the cockpit, even if you dont
have perfect vision.
Automatic shift tracking.
The SpeedPucks shift tracker locks on to the mean heading
for your tack and then shows deviations from that heading with an
easy-to-read bar graph. If you tack or jibe again, the shift tracker
detects this, resets the bar graph and locks on to your new tack.
All this happens 100% automatically; you dont need to press
any buttons to make it happen. The SpeedPuck constantly crunches
the numbers for you in the background so that, whenever you happen
to glance at the instrument, you can see how far youre up
The SpeedPuck is designed for long-term reliability
in a saltwater marine environment. The device's case back screws
off like the lid of a leak-proof water bottle to reveal the battery
The SpeedPuck's battery compartment is
also sealed off from the rest of the device's electronics, providing
a second layer of protection against moisture.
