    SETUP MENU

From the Main Menu select Setup. From there, use the menu navigation steps described above to 
navigate, select, adjust and exit setup options:

Input 

     

The Speed (and distance) Input setting can be set to GPS or Impeller.  Please note that you will need a 
wiring harness and impeller to use the Impeller mode. 
HRM Setup* 
Selecting this option will automatically attempt to pair the Heart Rate Monitor (HRM) Belt with the 
unit.  If more than one belt is found, you may need to change locations to isolate belt.   The HRM will 
automatically turn on when attached to your body.  The belt works best with moisture, so if you are 
not getting a reading, place some moisture on the rubber contacts of the belt before attaching to your 
body.  Once the belt has been paired with the unit, you will not need to pair in the future (unless you 
select Forget HRM or change belts).

Speed/Distance Setup 
Options are Speed mode or Split mode.  Speed mode will display your speed in the top left window.  
Split mode will display your pace expressed as a time to cover a distance (usually 500 meters).   Units 
allows you to change the units shown for speed and distance (options are:  M, M/S, /500 M; KM, KMH, 
/500M; or MI, MPH, /MI).
Auto Pause 
If toggled ON, the unit will stop the timer if it does not detect a stroke within the last 6 seconds.   If 
toggled OFF, the unit will not stop the timer even if no strokes are being detected.  If you would like to 
stop the timer manually, please select the   button to start and stop the timer manually.   Please note:  
the unit will not Auto Pause during the Rest sessions of a Workout.

NOTE: 

Average Speed is always calculated as a function of the distance covered in the elapsed time shown.  

Because the timer will continue to run while you are not rowing, turning Auto Pause “OFF” will impact the 
calculation of your cumulative average speed.

Advanced 
To access more advanced setup options, see below.

IMPELLER CALIBRATION 

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 performance 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 av-
erage 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 footstretcher 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 seconds at a 2:00 
/500M split pace. Distance accuracy is +/- 2.5M over any distance.

WARNING!  LITHIUM-ION POLY BATTERY HAZARDS

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 charge in direct contact with flammable items.
•  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.

•  Allow good air circulation around top and sides of unit while charging. 

ADVANCED SETUP MENU

Impeller Calibration  
To change your Calibration Value or run the calibration routine (see below).

GPS Spd Smoothing, Strokes  
The Speed Smoothing feature will average the last number of strokes selected. If “2” is selected, for 
example, the Speed/Split displayed will be an average of the last two strokes, updated every stroke.
Stroke Rate Setup 
Options are Timer Start Acceleration, Noise Filtering and Axis. 

Timer Start Acceleration  
Governs the degree of acceleration that must be detected to start the stroke meter. The default value 
is 4. If you increase this value, a more forceful stroke is needed to start the timer. If you decrease this 
value, a less forceful stroke is needed to start the timer. 
Noise Filtering  
Governs the degree to which the accelerometer will register changes in acceleration as a stroke. The 
default value is 3. If you increase this value, more acceleration is needed to register a stroke. If you 
decrease this value, less acceleration is needed to register a stroke. 
Axis 
Allows you to select Front-Back (2) or Any (3).   Front-Back (2) is generally recommended for rowing 
assuming that the unit will be mounted perpendicular to the long axis of the boat.  If mounting at a 
non-perpendicular axis, the recommendation is to toggle to Any (3). 

Time and Date 
Used to change the format of the date and time displayed.  Please note: only time shows on the display, 
date will be shown on data recall screen. Please note in most U.S. locations daylight savings time is ON in 
the summer and OFF in the winter.
Diagnostics 
The Diagnostics screen  provides information about the performance of your unit’s GPS receiver, acceler-
ometer, HRM*, clock, and charging system.   This information assists NK tech support in case your unit is 
not functioning correctly.

Calibration is only relevant if you are using your SpeedCoach GPS with a wiring harness and speed 
impeller. 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. Calibration applies only when in Impeller mode for speed and distance can average out any 
impact of current or tide to improve the accuracy of the calibration results.

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.

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 and tide 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 Calibration Value will be displayed.  Press 

 to accept the new value 

and exit the  routine, or press 

  to exit the routine without changing your Calibration Value.  

At any time while running the calibration routine, you can press 

 to exit the routine without 

changing your calibration value.

Memory Storage
When the memory is full, the unit will stop recording data. When 
nearing or at full data, delete all session data to continue recording 
(see below). The amount of memory used can be found on the 
bottom of the Recall Menu. An alert message will appear when 
memory log is nearly full. 
Data Recall
Select Data Recall from the Main Menu to review stored data.
Recall memory will be formatted in sessions according to date and 
time. Just Row sessions will have the JustGo prefix whereas a Work-
out session will just show the pieces run*.  

Please note:  a session is not complete until: a) In Just Row, you reset 
the counter b) In Workout, the workout is completed or cancelled.

Delete All Session Data 
This selection will delete ALL memory if chosen. Sessions cannot be 
deleted individually.
Viewing Sessions 
Selecting a session will bring up the Session Overview (Figure 1). 
The overview provides the overall distance, time, avg split, and avg 
stroke rate during that session. Selecting the Session Overview 
will bring up the Session Details (Figure 2). This page will show the 
session breakdown by specified  period (time or distance). Select  
MORE to view additional measurement values not currently shown 
on the screen.
