IMPELLER CALIBRATION
Calibration is only relevant if you are using your SpeedCoach GPS with a wiring harness and
speed impeller at times. The Calibration Value is an adjustment factor that compensates
for any difference between your impeller’s distance measurement and the “standard boat”
upon which the SpeedCoach’s calculations are based. The Calibration Factor applies only
when in Impeller mode for speed and distance.
Entering Impeller Calibration
Select “Impeller Calibration” from the Advanced Setup Menu.
Entering a Calibration Value Manually
If you know your boat’s SpeedCoach calibration value from previous
calibration (it is the same for any SpeedCoach), you may enter it manually.
From the Calibration Menu, press to select the Calibration Value, then
press to adjust the value, and to accept the value.

irreparable damage to electronic components and void your warranty.
Register your SpeedCoach GPS!
Your warranty period will be measured from the date of your purchase if it can be proven,
or from the date of manufacture if it cannot be. The best way for you to ensure full warranty
coverage is to REGISTER your product promptly under the support section of NK’s website.
We keep your registration information in strict confidence and do not sell it, share it or use it
for anything but product-related information bulletins (which you may decline receiving).
BATTERY USE AND CHARGING
A fully charged battery will provide approximately 6-8 hours of operation, depending on
backlight use. Each bar on the battery indicator represents 20% of battery life, or approxi-
mately 1.2 to 1.6 hours.
To charge your unit, press it firmly into the charging dock of your SpeedCoach GPS charger
until it clicks and you see “Charging ...” on the screen. The battery indicator will flash and the
bars will indicate the charge status achieved. The battery indicator will show full and stop
flashing after 90% charge is achieved, and the display will turn off when the unit is fully
charged.
The SpeedCoach GPS can only be charged with the supplied charging dock. The Speed-
Coach GPS is compatible with any USB charging source, including your computer or a
cell-phone standby power source. A SpeedCoach® XL charger will not charge a
SpeedCoach GPS.
Your SpeedCoach GPS contains a lithium-ion poly battery pack. Lithium-ion batteries
contain flammable liquid electrolyte that may vent, ignite and produce sparks when
subjected to high temperatures or when damaged or overcharged. If ignited,
batteries may burn rapidly with a flare effect and may produce irritating, corrosive
and/or toxic gases, including toxic hydrogen fluoride gas, which may cause
dizziness or suffocation. Contact with battery electrolyte may be irritating to skin,
eyes and mucous membranes.
• Do not ever subject to fire or temperatures above 140°F | 60°C. NOTE: A car in
hot sunlight may exceed these temperatures!
• Do not charge, use, transport or store above 115°F | 45°C.
• Do not charge below 32°F| 0°C.
• Do not puncture or open the unit.
• If the unit’s internal battery pack is damaged, avoid contact with battery
electrolyte, which may be irritating to skin, eyes and mucous membranes.
• In case of battery fire, evacuate the area to avoid inhalation of fumes. If
possible, cover the battery with sand to extinguish the fire or use a dry ABC-
type extinguisher.

Running the Calibration Routine
The SpeedCoach GPS does not need a measured course to be calibrated.
Because the SpeedCoach GPS knows both the GPS and Impeller distance
measured, it can self-calibrate. Calibration simply involves rowing the selected
distance in two directions. Your distance options are 500 to 1000M. Although
a longer distance will somewhat improve the accuracy of your calibration,
is important to choose a calibration distance that you can row in a relatively
straight line in both directions. Ideally, it will also have relatively consistent
current throughout. The Calibration Routine requires that you row your course
in both directions so the unit can average out any impact of current, tide or
wind, and to improve the accuracy of the calibration result through more
comparison data.
If you wish to change your calibration distance from 500M, press to
move to the distance line, to select, then to adjust and
to accept.
To run the calibration routine, press to highlight Run on the
Calibration Menu, then to select. From the calibration screen, press
to start each calibration leg and follow the screen prompts. On each leg, the
land distance and water distance will count up until the selected distance is
reached in the land distance window (bottom left). Note that there will be a
three- or four-stroke delay at the start of each leg while the GPS and impeller
readings are synchronized. At the end of the routine, the newly calculated
value will be displayed. Press to accept the new value and exit the
routine, or press to exit the routine without changing your calibra-
tion value. At any time while running the calibration routine, you can press
to exit the routine without changing your calibration value.
SPECIFICATIONS
GPS FUNCTION AND ACCURACY
Your SpeedCoach GPS employs a high-precision 5-Hz GPS receiver. This means it receives
GPS position and speed data from the GPS satellites 5 times a second. This update rate,
which is five times that of any running watch on the market, is necessary to provide the
data density for accurate stroke-by-stroke rowing speed. Your GPS receiver’s perfor-
mance is dependent upon having an unobstructed view of the sky. After passing under
a low or wide bridge, you are likely to notice erratic speed data for a stroke or two. Your
unit will return to accurate values as soon as it has re-established good satellite signal.
A higher setting for speed-smoothing strokes will dampen both the initial error and the
return to valid readings. Note that your total distance, elapsed time and average speed
will not be affected by these few strokes of erratic speed readings. You may also notice
slightly degraded speed performance (less stable readings) on extremely overcast days.
Note that when using your SpeedCoach GPS in team boats at a seat other than stroke
seat, the body of the rower in front of you may interfere with the GPS signal, particularly
if you are both long-legged. If possible, move the SpeedCoach to the side of the foot-
stretcher so that it is not directly under the body of the rower in front.
The GPS receiver provides speed accuracy of +/- 0.1 m/s, which translates to +/- 3 sec-
onds at a 2:00 /500M split pace. Distance accuracy is +/- 2.5M over any distance.
