Hello Robert, Yes that is going to be part of the plan. The CoxBox GPS will be the central host of all the data for one export to the cloud for data. This will cut back on uploading 8 separate SpeedCoaches and saving a lot of time. LiNK Logbook will be the place you can upload: https://nksports.com/link-logbook Regards, Joe Racosky jracosky@nkhome.com ... Read more
Hello Robert, The battery is encased inside the unit for the new CoxBox GPS so you cannot remove them. They are going to last 10 hours on a full charge however and should last 5 years or so overall. When a new battery is needed, it would have to come in for a repair for a nominal cost. The replaceable batteries were causing too many issues and people prefer our older metal can CoxBoxes so this is what went into that decision. Regards, Joe Racosky jracosky@nkhome.com ... Read more
Hello, You would need the training pack version in order to upload the data, but yes you can plot a map of your row with the GPS data. Please check out our new app that will make this easy to do: https://nksports.com/link-logbook Regards, Joe Racosky jracosky@nkhome.com ... Read more

You will not get heart rate data fields until you actually pair the heart rate belt to the SpeedCoach. Please try going to the pairing menu on the SpeedCoach. Then while it is looking for the device, take the Polar buckle off the belt and rub the contacts to try and "wake it up". Hopefully this helps with pairing. Then once paired, you should be able to scroll through the heart rate data fields.

I am not sure if you have the older style Cox Box microphones (metal connector) or the newer style (rubber connector).

Typically we can repair the older style by replacing the connector ($35): https://nksports.com/nk-sports-service-request

If it is the newer style, we typically cannot repair them. If they are still within the 2 year warranty period, please send them in as above.

Hello,

It sounds as if the heart rate belt isn't detecting a heart rate for some reason for a little while and then shutting off. Once it detects it again, then it comes back on.

I would try cleaning the heart rate belt to see if that helps. One is the contacts on the buckle, see here: https://nksports.com/faqs/question/view/id/173

The other are the rubber straps that go ahead your body. You can use a mild soap and warm water to clean these off. Hopefully this helps.

All of our oarlocks are pitched around 3.5 - 4 degrees and there isn't a way to really change this. We have had customers use tape on the oarlock to adjust the pitch and this works somewhat well but other than that, we do not have a way to change this currently.

The original had a BNC (metal) connector. The 08 has the rubber plug that you need for the Mini. So you would need this one: https://nksports.com/microphone-with-headband-cox-box-08

Does your SpeedCoach have the Training Pack installed on it? Go to Main Menu->About and check to see if Options say "Training Pack" next to it. If not, then you will not be able to upload the data.

If you have the training pack, are you using the provided Bluetooth dongle to connect? Does your SpeedCoach connect to LiNK? Are you putting the SpeedCoach in Data Link mode? Please let me know a little more of the situation and we can get it fixed for you.

... Read more

You can either purchase a Bluetooth dongle (PN 0126) from our site and use that to update with Windows or MAC and our LiNK program.

Or, you can just connect your SpeedCoach to our NK LiNK for iOS or NK LiNK for Android and you should be prompted about a firmware update.

Finally, if you want, you can send it in to us and we can update the firmware for free.

Hello Greg,

The SpeedCoach GPS is measuring land based distance as opposed to water based. So if you have any type of current, you could see differences in the distance. Do you know if the distance was off coming back the other way? I would expect it to possibly be off by the reverse of what you saw going the other way.

You mention that you wait a little after turning it on, this is good. You want to make sure the satellite icon goes from unfilled to filled in, before starting you paddle. There is no real calibration on these units to do. The thing i would have you check however is the satellite coverage you are getting. If you go outside and turn on the SPC, go to Main Menu->Setup->Advanced->Diagnostics. Scroll to the GPS Diagnostic screen. See how many satellites you are getting after a few minutes.

As for the black plug, this is just extra protection for the SpeedCoach as they do not float. The idea is to attach it to the board and run the lanyard through it. That way if the SPC gets knocked by the paddle from the mount, it will not go into the water. And we recommend leaving the float on the lanyard as well.

Here is our information on our FAQ page:

Force curves were made available in early rowing analysis systems because they are the most basic representation of the actual analog data from the force sensor, with no analysis applied. As a result, they're familiar, but that doesn’t mean they're ideal. Even after years of looking at and coaching with force curves, there is not much agreement in the sport about what makes a "good" force curve. (Lots of opinions, but not much agreement!) Also, it is challenging for athletes to use force curves as a target for changing their rowing, particularly without a clear target also represented on screen. We have chosen to present primarily numerical data that breaks the stroke down into clearly understood elements because we have demonstrated to ourselves, and many other coaches and athletes, that simple numbers are much easier to focus on when attempting to make changes or assess progress.

Because the EmPower Oarlock logs five key elements each and every stroke (catch angle, slip, peak force, peak force location, wash and finish angle), we are also able to present a clear "picture" of the stroke very similar to a force curve which we call a "Stroke Profile".

When charted using a simple Excel template, the Stroke Profile illustrates these key characteristics of one or more rower. In the example below, four scullers were evaluated during 20' session. We can see that Rower #2 is probably rigged too far into the bow (see their shallow catch angle and deep finish angle). We can also see that Rower #2 has their peak force occurring later in the drive than the other three. The coach can now provide Rower #2 with a target Peak Force Angle of -10 to -20° in order to better match the other rowers in the boat. Rower #2 can monitor himself as he rows future sessions.

To create your own Stroke Profiles, please see Excel Templates and instructions on how to use them below: https://nksports.com/mwdownloads/download/link/id/262/

Essentially you would plot your information in the Excel template. You will see your slip, wash, catch angle, finish angle and peak force angle. There isn't any black and white guidance for this as some people have a peak max angle before 0 degrees and some after, depending on your technique. The best way to use this is to make adjustments and see how it affects your profile, what makes it better vs worse.

Another resource is the website rowsandall.com. You can upload the data into this site and plot and graph all the oarlock information.

Sorry for the late reply. No you cannot. The SpeedCoach only has a satellite receiver to pick up GPS satellites. It does not have the ability to send out a GPS signal which would be needed to find it.

Hello Thomas,

When you upgraded the unit to 2.19, did you run the firmware installer twice? There is a Bluetooth profile update that runs after the firmware update, so I would run the update a second time to update the Bluetooth profile. You can check your Bluetooth Profile on Main Menu->About->BLE Profile. The latest is BLE Profile Version 0.03. This can help with some heart rate issues.

Next, in all the troubleshooting that you mentioned I didn't read about replacing the battery. Some of the symptoms could be from a weak battery in the heart rate belt. Please try replacing the battery in the heart rate belt and see if that helps. I believe it should be a CR2032 battery but double check.

Lastly I would recommend cleaning the contacts of the heart rate belt buckle. Here is an FAQ on this: https://nksports.com/mwdownloads/download/link/id/164/

Corrosion can also cause some of the symptoms you describe. I believe between the suggestions above, these should help but let me know if you still having issues.

Regards,

Joe Racosky

Hello,

You cannot pair two oarlocks to one SpeedCoach at this time. We will look to add this in the future at some point but you would need 2 SpeedCoaches and 2 Oarlocks to view both at once. I will point you to our FAQ on this subject:

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.

The angle tool automatically comes with an oarlock purchase and is needed.

SN 2300180 already has the training pack installed.

Joe Racosky

The SpeedCoach GPS does not use a seat sensor. It calculates the stroke rate by an internal accelerometer. You can use a impeller with it but not a seat sensor.

Hello Charles,

You do not need to pair the SPC to the iPhone directly and this will most likely not work. You should just open the NK LiNK app and turn the SPC to Data LiNK mode and it should appear in the app to connect. If you have paired the SPC to the phone, please unpair it before trying to connect to the app.

Regards,

Joe Racosky

In order for the NK Live LiNK to work with a mobile device, the mobile device needs to be Bluetooth Peripheral capable. This means that the phone can accept pairing from an outside device, such as the SpeedCoach. It is a little tough to tell which phones are able to do this but most of the latest phones can. I believe this is the issue with the Pixel XL however. This device is not designed to have the ability to accept Bluetooth pairings from outside devices. Unfortunately I do not have a fix for this as you will need to try a different device.

Joe Racosky

Hello Brad,

Sorry for the trouble with your SpeedCoach. We do not provide shipping to our company, but we do cover the return shipping back to you. So you would be responsible for the costs to get the unit to us and we would cover everything after that.

Hello,

It sounds as if the Bluetooth dongle is not being picked up by the program. To resolve this, please try the following:

  1. 1) Remove all the peripherals attached to your MAC.
  2. 2) Turn off the MAC and wait 5 minutes.
  3. 3) Turn on the MAC and reconnect all the peripherals, including the Bluetooth dongle.
  4. 4) Open up the NK LiNK Program. At the bottom of the screen, it should say Searching for SpeedCoaches now instead of Searching for Dongle.
  5. 5) Put your SPC in Data LiNK mode and it should appear.

The issue with the program not re-opening after closing is something we are looking into as we have had other reports. Regards, Joe Racosky

Hello,

This issue has come up during our testing of this new technology. We are going to be implementing a setting to select between GPS and Impeller mode in the app so this should take care of your issue. I don't have a timetable for when that will be available but hopefully won't be too long. Please be patient as we work to keep improving this app and we certainly appreciate any and all feedback during this process.

Hello,

You are not able to use the cable to connect to the computer, it is only for charging. If you do not want to purchase another dongle, I would suggest using our LiNK mobile apps. We have NK LiNK for Android or iOS and either can update the firmware through the phone without using any additional equipment. Once you connect to the mobile app, you will get prompted about a firmware update.

Hello Vladimir,

You need to have a Bluegiga BLED112 Bluetooth dongle to work with the SpeedCoach GPS. You can get them online from different places but it has to be this specific model.

If you open up the LiNK program and have the dongle and it still says "Searching for Dongle" in the lower left of the application, you may have to download the driver and manually install it.
