SpeedCoach® GPS - Model 2

was $449.00 Special Price $399.00

SpeedCoach GPS Model 2 is now only available with Training Pack.

Rowing's most popular performance monitor, the SpeedCoach GPS 2, offers athletes critical information about boat speed (split), stroke rate, distance, and time. Use by itself in GPS mode or connect to an impeller (impeller and wiring sold separately) for additional accuracy in moving water. The Training Pack features now come standard. Program any workout ahead of time, start and record pieces without letting go of the oar handle and upload the data wirelessly to a computer or mobile device. The SpeedCoach GPS with Training Pack supports the EmPower Oarlock and is the central component of NK’s connected rowing environment.

NOTE: The SpeedCoach GPS 2 is designed for rowing. Please see the SpeedCoach SUP 2 or SpeedCoach OC 2  if you are looking for a SpeedCoach for stand-up paddleboarding or outrigger canoeing.

SpeedCoach GPS 2 is

Impeller Compatible

The SpeedCoach GPS is compatible with our SpeedCoach Impeller (sold separately). Training with an impeller has been the gold standard for rowing for years, especially for teams that train on moving water. Impeller speed measures the movement of the boat relative to the water, while GPS speed measures the movement of the boat relative to the ground. This can be a powerful training tool and a great way to learn more about your paddling. To get started training with an impeller, you will need the SpeedCoach Impeller Wiring, Wireless Angle Bracket Mount, and SpeedCoach Impeller.

If you are interested, we wrote a blog post highlighting the differences between impeller speed versus GPS speed.

  • This file will breakdown your workout view to the stroke level. You can also use this data to graph within Excel
  • You’ll get a session summary at the top of the page, and then interval summary below that, and then the session detail, which will show you your information at each stroke.
  • You can also upload csv files to rowsandall.com to view the data graphically, including Empower oarlock data.

If the battery has become very flat (low), it may take a little longer for the unit to show that it is charging. First please make sure the unit has “clicked” into place on the charger so that the silver contacts are aligned together. Then make sure you give the unit at least 30 minutes for the “charging” to appear on the screen. Typically after 30 minutes you should see a change from a blank screen to “charging”. If the unit is still not responding after more than 30 minutes on a charge, please contact NK for assistance.

Unfortunately there are hardware differences between the GPS 1 / SUP 1 and the GPS 2 / SUP 2 so they cannot be upgraded. We offer customer trade-ins for anyone who would want to upgrade their current model SpeedCoach into a GPS 2 or SUP 2. The details of the trade-in program can be found here

No, the SpeedCoach has a lot of dense electronics inside and this causes it to not be buoyant. Please make sure you secure your SpeedCoach to your mount using the lanyard. Extra precautions such as the NK Life Preserver Float should also be considered.

No. Unfortunately the SpeedCoach has a GPS receiver, not a transmitter. So while it can receive GPS signals, it cannot send a GPS signal. If you lose you SpeedCoach, NK has no way of detecting where it currently resides.

When you update the firmware on your GPS unit, the heart rate belt will need to be re-paired. You will also lose all session data currently on the unit.

  • GPS 1 / SUP 1:NK no longer carries a heart rate belt that works with the SpeedCoach GPS 1. The Wahoo Tickr model is the best choice to use if your original belt no longer works (Please Note: not the Tickr X model however).
  • GPS 2 / SUP 2 / OC 2: Any heart rate belt that connects with Bluetooth Low Energy (BLE) should work.
... Permalink

If you are sure that your belt is paired but is either not showing a heart rate or showing an erratic heart rate, it may be one of a couple issues. First if you are getting “---“ make sure there is enough moisture on the heart rate belt’s rubber contacts against your body. Very dry skin may not be enough to create enough of an electrical connection to get a proper reading. Secondly, if these rubber contacts are dirty, this can also cause a problem. Our suggestion is to use mild soap and water and clean the belt occasionally to help prevent dirt build-up. Finally if neither of these suggestions help with your issue, the problem is most likely related to corrosion in the heart rate belt buckle contacts. Please see the document below to clean these contacts to help restore proper connectivity.

For many customers, the stroke rate should work great right out of the box with the factory settings, but there may be some customers that need to make some slight tweaks to the unit in order to get a better stroke rate reading.

First you should make sure the unit is properly mounted so that it is directly facing you (perpendicular to the port or starboard sides). If you need to mount it on an angle, for example a 45 degree angle from the port or starboard side, then you will need to toggle the Axis to Any (3). You can do this through the Main Menu->Setup->Advanced->Stroke Rate Setup->Axis. For the majority of the time we do recommend leaving the setting on Front-Back (2). This is especially true if you have choppier waters. If you are in choppy waters, it is best to remove the Z-axis motion and set the axis to Front-Back (2). If you are having issues with the unit detecting too many strokes or not enough strokes, our recommendation is to adjust the Noise Filtering setting. To do this, you would go to Main Menu->Setup->Advanced->Stroke Rate Setup->Noise Filtering

Note:

  • If you are getting more strokes than you think you should be getting, please raise the Noise Filtering value (default is 3).
  • If you are getting less strokes than you think you should be getting, please lower the Noise Filtering value (default is 3).
... Permalink

When you are in Ready mode, the timer will start when it detects the first stroke. If the timer is starting prior to your first stroke, you may want to raise the Timer Start Acceleration setting. Please go to Main Menu->Setup->Advanced->Stroke Rate Setup->Timer Start Acceleration and raise this value slightly (default value is 4). If, instead, the timer is not starting on your first stroke, the remedy would be to lower the Timer Start Acceleration value slightly (default value is 4).

... Permalink

When set to ON, auto pause will stop the timer if the unit has not recorded a stroke within the last 6 seconds. It will automatically start again once a stroke is again detected. If you leave Auto Pause to OFF, then the timer will continue the entire time, whether a stroke is detected or not.

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.

... Permalink

When the SpeedCoach GPS/SUP is powered on, it begins to search for GPS satellite signals. Until the SpeedCoach acquires a strong GPS fix (typically under 2 minutes), the location and speed measurements can be erratic. If the timer has been started during this period, you may see jumps of up to 100m per stroke. It is recommended to allow at least 2 minutes between powering up the SpeedCoach and starting a Just Go session or a workout.

... Permalink

To change the battery on your heart rate belt, please see this document:

  1. Turn on the unit when you get outside.
  2. Allow for up to 3 minutes for the GPS to get a satellite lock.
  3. (If applicable) Pair your heart rate belt to your unit. Main Menu->Setup->HRM Setup->Pair HRM
  4. Select Speed/Distance Setup: Split or Speed. Main Menu->Setup->Speed/Distance Setup.
  5. Go back to the main screen. Adjust the flex (bottom) windows by using the up and down buttons to change the measurements shown to your personal preferences.
  6. Before rowing, press the Power button once to set the unit into “Ready” mode.
  7. Start your row.
  8. If you want to take a rest, press the power button to put unit in STOP mode.
  9. Press the power button to put the unit back in READY mode when ready to resume.
  10. Once completed with the row, hold the power button until “Reset” appears to save your rowing session (Please note: session will also be saved if the unit powers off).

No. The SpeedCoach GPS can be used without any additional wiring. The stroke rate is picked up by an internal accelerometer and the speed and distance are picked up by satellites.

... Permalink

Yes. You can toggle the Setup->Input to Impeller. The unit will then get the speed and distance from the impeller instead of the GPS satellites. With the latest firmware installed, the unit will record both GPS and Impeller speed and distance when using with an impeller. It is also recommended to run the impeller calibration on a per boat basis, if using the impeller.

First please make sure the unit is set to Impeller mode when you go to Main Menu->Setup->Input. Next make sure the impeller is free of any debris and is spinning freely. The next thing to check is the location of the impeller versus the impeller pickup coil. These need to be positioned above each other and as close as possible. The GPS has even greater sensitivity than other SpeedCoach models, so if it works for say a SpeedCoach Gold, but not a GPS, you will need to move the impeller and impeller coil even closer together (if at all possible). See next question on how to properly mount an impeller.

Below is a procedure that has been successful for other customers:

Requirements

  • Two People
  • One Sharpie
  • Goof-Off
  • wiping cloth or paper towel

Steps:

  1. Put the boat in slings right side up.
  2. Assuming the speed pickup is installed so that it is aligned parallel to the long axis of the hull, put one forefinger on the tip of the pickup furthest from the cable that connects it to the cradle. Then try to put the other forefinger on the bottom of the hull in the location where it would touch the other forefinger if the hull were not there. Use the Sharpie to make a dot marking that spot.
  3. Hold the impeller unit against the hull so the impeller propeller is next to that dot.
  4. Put the SpeedCoach into the cradle, turn it on, and set it to read speed via impeller.
  5. Make the impeller spin by blowing on it and see have your helper see if a speed reading appears on the SpeedCoach. If not, try moving the impeller unit forwards and then backwards and blow on it to find where you get a reading.
  6. Once you have a reading, mark that spot if it is different from the spot where your forefinger was.
  7. Then define the range where you can get a reading, by moving the impeller unit forwards, finding the spot where readings cease, and marking that spot. Then move it backwards and mark the spot where readings cease.
  8. Center the impeller unit between those two locations, mark that spot, and attach the unit to the hull with VHB tape
  9. Test again by blowing on it to confirm that it works.
  10. Use Goof Off to wipe away the markings

This method will work for ANY SpeedCoach impeller mounting.

The unit will shut off after 10 minutes of inactivity. If it is registering a stroke rate, it should not shut off. If the timer isn’t running or distance isn’t accruing, you most likely are in STOP mode. Please hit the power button to set the unit in READY mode. If you would like to turn this off (so the unit will always keep running unless you shut it off), go into Main Menu->Setup->Auto Shutdown, and toggle it from 10 min to OFF.

LiNK data can be reviewed in the application itself by simple clicking on a data session. This will give you a session and interval summary as shown below.


You have the ability to click on a specific interval and view the details by clicking on an interval. You can also cut and paste the data from LiNK to a new document for 100 meter increments


If you would want to review stroke by stroke details, you wll need to export the data as a CSV file

First please make sure that you have the training pack version installed on your unit. The training pack is required for downloading data sessions to a computer. You can review this on your SpeedCoach unit by going to the Main Menu->About and note if Options reads “Training Pack”. While on this screen, please review that you have firmware version 2.04 or higher. If you have a firmware version below, 2.04, please update your firmware per the instructions.

Next please make sure that the computer is picking up the dongle correctly. When you open up the LiNK application, the very bottom left of the application window should say “Searching for SpeedCoaches.” If the application instead says “Searching for dongle”, then you will need to troubleshoot the Bluetooth dongle. There is help here to install the Bluetooth driver

Once you have verified the above and have connected to your SpeedCoach, please first ensure there is data sessions stored on the unit. If you recently upgraded the firmware, you may have erased all the data sessions. Otherwise, please just be patient with the program. We have found that on some Windows computers, data transfer takes a long time (up to 30 minutes in the worst cases). Some of this can be alleviated from disabling other Bluetooth devices, but sometimes anti-virus and other programs can delay this transfer. The data session will transfer eventually though, if program is saying “Not Responding”. The program should eventually alleviate the issue and transfer the data.

While it may appear the LiNK for Windows application is locking up, it should eventually resolve itself and transfer the data. If it appears that the LiNK for Windows program has become unresponsive, please be patient and let the program resolve itself and the data should eventually transfer. This could take up to 30 minutes although this is definitely not typical in most cases. We are working on improving this connection for Windows users.

If you stopped the LiNK program prematurely (even if the program said "Not responding"), the data might have become corrupted during the transfer. Please erase the sessions from the LiNK program and try and upload the data sessions off of the unit again. Please allow the transfer to complete without any interruptions.

You can view stroke-by-stroke details of your data session by exporting the data as a CSV file. Using LiNK Logbook, you would just email them to yourself. For LiNK for Windows or OSX, unless you changed the path, all exported files will be found under:

  • For Windows: My Documents->LiNK for Windows->Exported Files
  • For OS X: Documents->LiNK for OS X->Exported Files

To update the firmware using a Windows or MAC computer, you must first run a program to import the latest firmware files from our site. To do this, please open the NK LiNK software. Click on the Help tab at the top of the screen. Click on the link found under Step 1 of the instructions and run this program. Link will be an .exe file for Windows users and a ZIP file for OS X users. For Windows run the .exe program. The next time you connect your SpeedCoach, you should be prompted to update your firmware. Just click Yes to update. For MAC users, follow the directions in the zip file. If you do not get automatically prompted, you can go to the Manage tab and select Update Firmware. If you are not prompted again, you most likely have the latest firmware available. Alternatively you can connect to the LiNK Logbook mobile application. Go to the More Tab and select Frimware update. Make sure SpeedCoach is in Data LiNK Mode. Note: All data sessions will be deleted from the unit after updating the firmware. The heart rate belt will also need to be re-paired.

With our focus on simplicity of installation, pairing and understandability, the initial release of the system is a one-to-one pairing between oarlock and SpeedCoach. Every oarlock needs a dedicated SpeedCoach to view and log its measurements. The SpeedCoach is hardware capable of pairing to multiple oarlocks, and we will offer this option as a firmware update in the future.


But wait! I'm a sculler, and I clearly use two oars!

While it is absolutely true that all scullers have differences in their stroke between their left and right hands, these differences (a) cannot be TOO great or the boat would never go straight; and (b) are generally smaller in their impact on boat speed than the larger elements which can be captured on either side. When in sculling mode, the SpeedCoach doubles the Work and Power values obtained from the single Oarlock so the effective athlete output is shown. We are in part choosing to release the EmPower Oarlock for sculling as a one-to-one system to learn more about the typical combinations of measurements preferred by scullers so we can create a simplified and manageable user interface for displaying the MANY values available when you double the number of Oarlock measurements to be displayed. We promise you will see that the system is incredibly powerful with only one Oarlock as soon as you try it. Note that you can also swap sides occasionally to compare results because the Oarlock is so quick and easy to install and can be used on either side.

  10. Finding the Boatmovers Finding the Boatmovers Until recently, the most accurate metric for on-the-water performance has been the 500-meter split. It makes sense: races are measured in time over distance, so why not measure practice pieces the same way? If the goal is to improve an athlete’s performance, a logical requirement is to be able to accurately measure that performance. The biggest problem with using splits to gauge improvement is that boat speed doesn’t just depend on the athlet
  11. "Working" My Core with the EmPower Oarlock By Alix James I've been working through the real-time measurements available with my EmPower Oarlock connected to my SpeedCoach GPS – exploring the relationships between my rowing stroke and what the numbers on the screen are telling me. I'm lucky enough to row with a coach on a somewhat regular basis as part of Vesper Boat Club's master's program, so I have a very good idea of the many, many ways I need to improve. It has been really interest
  12. Everything You Ever Wanted to Know about the SpeedCoach but Were too Afraid to Ask: Part I Everything You Ever Wanted to Know about the SpeedCoach but Were too Afraid to Ask: Part I No matter how much you know about rowing, it's easy to feel uneducated. It may have been ten days or ten years since you've figured out that "coxswain" is pronounced "cox sin," "gunwale" is pronounced "gunnel" and "weigh enough" means "stop," but there's still a whole world of terminology, measurements and equipment to understand.
  13. Length and Effective Length Are Not The Same Thing Sander Roosendaal, Czech masters rower and data guru, created a rowing analytics platform that incorporates data from many on-the-water and off-the-water devices, including the NK SpeedCoach and EmPower Oarlock. The free to use platform and Sander's insights into his own rowing data are available on the Rowsandall website.
  14. GPS vs. IMPELLER NK has now released the SpeedCoach GPS Model 2 that uses a 3 axis accelerometer & a 5 Hz GPS (Garmin & others are only 1 Hz). This now addresses the issue of slow updates of boat speed. The problem of moving current still remains: you are measuring the speed relative to land. The NK SpeedCoach overcomes this by being able to be switch to Impeller mode, therefore having your true speed relative to the moving water.
