Basics
Batteries
The SpeedPuck is powered by an onboard rechargeable battery.
Battery Life
The battery indicator is located on the bottom of the LCD screen. When the battery is fully charged, the
device will last 30 hours in normal operation. When the battery is empty the device will go into low
battery mode and flash the battery outline.
When the battery is exhausted, connect the SpeedPuck to a USB port or a phone charger using the
supplied cable. From low battery the SpeedPuck takes approximately 10 hours to charge completely
using a 5 volt, 1 amp wall adapter (iPhone or similar) or 50 hours to charge completely via a USB port on
a computer.
Battery Indicator
The battery indicator on the SpeedPuck is located on the bottom right of the LCD screen.
Signal Acquisition
The operation of the SpeedPuck relies on low-power radio signals from GPS satellites that orbit the earth
at an altitude of approximately 20,000 km. As a result, the SpeedPuck must be outdoors with a clear
view of the sky to function properly.
When the SpeedPuck is first turned on, it must download information from GPS satellites before it can
acquire a GPS solution. The data download process can take up to 5 minutes.
Installation Guide
The SpeedPuck can be installed anywhere on the boat with a view of the sky. The SpeedPuck comes
with an injection molded plastic clip in cradle for easy installation. Install the cradle permanently on
your boat. Press the tab on the cradle to release the SpeedPuck from it.

The SpeedPuck Cradle works with M4 Metric flat head countersunk machine screws. Alternatively, you
can use Imperial No. 6 flat head countersunk machine screws in place of M4 fasteners. Always use
Marine Grade fasteners when mounting the SpeedPuck Cradle and/or Mounting Brackets.
Do not use rounded head screws with the SpeedPuck cradle. Non-countersunk screw heads will interfere
with mounting the SpeedPuck in its cradle.
Since the introduction of the SpeedPuck Cradle, the SpeedPuck no longer comes with the 3M Dual Lock
on the back of the battery compartment lid. Several alternative mounting options are available,
including 3M Dual Lock. For details, go to https://www.velocitek.com/collections/accessories.
GPS Data Storage
The SpeedPuck records GPS data whenever the device is on and GPS signal is detected. The device
records data four times per second (4Hz). The SpeedPuck can store 1000 hours of data when recording
GPS data at 4 Hz.
If the memory is full, the oldest data will be overwritten.

Operation
In firmware version 1 of the SpeedPuck, Sailing Operation is the only operation of the SpeedPuck.
Sailing Operation
The sailing operation is for those racing dinghy boats. All modes are enabled for maximum
performance.

Displays
Following are details on the various displays.
Speed
Speed is calculated by the GPS unit by measuring the Doppler shift in GPS signals. Speed is displayed in
Knots (Nautical Miles per Hour).
Heading
Course Over Ground (COG), or GPS Heading, is calculated by the GPS unit by measuring the Doppler shift
in GPS signals.
In firmware version 1, your COG is displayed in degrees True. Degrees True is referenced to true north.
The SpeedPuck displays heading only when your speed is greater than 0.5 knot, otherwise it will show a
heading of “- - -“ degrees regardless of which direction you are actually moving.
The difference of the SpeedPuck to a conventional magnetic compass is that the SpeedPuck measures
the direction the device is moving in rather than the direction it is pointed in. A major benefit of the
SpeedPuck over a conventional magnetic compass is that it will give you accurate heading information,
regardless of the orientation in which it is mounted on your boat. SpeedPuck 's compass reading
depends only on the direction you are moving, not the direction the device is pointing.
Max Speed
Instantaneous max speed displayed is a best two second average. Using the SpeedPuck’s high-speed, 18
Hz, GPS module.
The max speed is stored on a session-by-session basis and it is reset when the SpeedPuck is turned off.
Lift/Header Bar Graph Indicator
The SpeedPuck automatically detects when a sailor is trimmed to a heading then provides the header/lift
indication. When the device detects that the sailor is trimmed at a heading the trim angle is set. Then
header/lift indication is given off of that trim angle. Once a tack or a jibe is detected the indicator
resets and nothing is indicated until another trim angle is set. Each bar segment represents 3 degrees
of wind shift.

6
Configuration
In firmware version 1 the SpeedPuck has no user configurable settings. User configurable settings are
planned in future firmware versions.
Software
The SpeedPuck works like a USB thumb drive and does not require any software to communicate with
your computer.
Velocitek Control Center
The ProStart no longer requires you to use Velocitek Control Center in order for the ProStart to
communicate with your computer.
Replays

Maintenance
To ensure your SpeedPuck's enclosure remains watertight and the electronics are not destroyed by
corrosion, please take the following precautions:
•Dry case with a towel before opening.
•Wipe away sand or debris on the gasket before screwing the back case on.
•Once the case is open wipe away any loose water droplets.
•If you ever see signs that water is leaking inside the enclosure please contact Velocitek
immediately at (866)-498-6737 or [e-mail] to arrange for your device to be
repaired and made watertight again.
