The CoxBox Core will display stroke rate, total strokes and elapsed time. It is functionally equivalent to the previous versions of the CoxBox.

The CoxBox GPS will show the same measurements as the CoxBox Core, plus show you measurements based on the GPS inside the unit. Additionally, you will be able to see distance, speed / split, and distance per stroke. The CoxBox GPS also records the data in memory which can be uploaded to our LiNK Logbook app.

The CoxBox GPS data and positioning can also be live streamed to the cloud for remote viewing when paired in the boat with a mobile device.

Here is a quick video that goes through how to navigate and use the new CoxBox Core / GPS

NK has integrated a variety of changes to improve the user experience and ensure a more robust product in the field. Below are some of those features:

• A single-piece faceplate and large, easy to read display provide a more rugged and waterproof design.
• Waterproof interface.
• Buttons are precisely located and sealed from the elements, reducing the potential for water to enter the unit. The lower profile design takes up less volume.
• New cylindrical battery design provides 10+ hours of battery life with a more reliable, sustained charge.
• Wireless Stroke Rate - No more dealing with sensors or magnets.
• Monoblock™ connector port relocates microphone, speaker/charging and data ports away from the face of the unit, creating better readability and simplified serviceability
• Stablesocket™ design prevents rotation and bending of plug inserts, which protects pins and sockets from damage.

Yes. The CoxBox Core/GPS are backwards compatible with legacy harnesses, speakers, microphones, chargers and mounting cups.

Adapting the Current CoxBox Cup Holder for the CoxBox Core/GPS Unit   (Size: 157.5 KB)

Here's how to quickly adapt your CoxBox Cup Holder to fit the CoxBox Core/GPS Unit

Yes. Older (even non-functioning) CoxBoxes can be traded in for $100 off a new CoxBox. This policy can be found here: Trade Up, Trade In

This connector is for a new wiring harness which acts as a data port and runs throughout the boat. This Smart harness is for a variety of additional accessories such as Smart integrated boat lights, Smart impeller, and Smart seat displays. These accessories will be introduced later this year.

This harness is optional and not required to use the CoxBox.

The battery is internal and not user replaceable. The battery life should be 2 to 3 times longer than the CoxBox 08 external battery. If the battery needs to be replaced, it would be sent back to NK for service.

Yes. You are able to purchase a CoxBox Core to GPS upgrade for the CoxBox Core to turn it into a CoxBox GPS for the difference in price. The customer is then emailed a file that is loaded onto the unit.

For saltwater environments, NK recommends to rinse with fresh water after each use. The connectors have been designed to point down slightly to help drainage of salt water and debris after use. NK still recommends monthly cleaning of the sockets and the use of Nyogel on the sockets to help reduce corrosion.

• Bigger Screen - Moving the connectors allow for a much bigger screen with access to more information.
• Bigger Keypad - This change also allowed for larger buttons, easier to manage when wearing gloves.
• Corrosion Prevention - When water and debris got into the connectors when on top, it would just sit there and create corrosion when not in use. The side connectors will allow for water and debris to drain after every use and help protect against corrosion. Although you still should rinse out salt water each time

Yes! Both units will float (even with the microphone attached) without any additional accessories.

Yes. Both units contain a Bluetooth Low Energy module that is used to communicate with outside applications and devices.

Please see this slide which shows how to change the settings:

How to View Impeller Mode in NK LiNK Logbook   (Size: 100.7 KB)

This slide shows you how to change the settings in LiNK Logbook to show Impeller distance and speed instead of GPS.

The CoxBox Core will show you stroke rate, total strokes and elapsed time. It is functionally equivalent to the previous versions of the CoxBox.

The CoxBox GPS will show the same measurements as the CoxBox Core, plus show you measurements based on the GPS inside the unit. Additionally, you will be able to see distance, speed / split, and distance per stroke.

Both units contain an internal accelerometer that measures stroke rate from the start and stop motion of the boat.

The short answer is no. As long as you charge the unit until it is full, the battery will rebalance itself. For a more detailed answer, you can check out this graphical explanation

Do I need to rebalance the battery in the CoxBox Core/GPS?   (Size: 200.5 KB)

A graphical explanation on why charging until full will ensure the battery is balanced every time with the new CoxBox.

You should get 2 to 3 times the battery life of the previous CoxBox 08. With a fully charged battery, you should expect 10+ hours of use.

If your boat is already wired for a CoxBox, no additional accessories would be needed. If you are wiring a boat from scratch, you would need the following:

• Coxed 4: A harness (0290), M harness (0292), 2 speakers (0207)
• Coxed 8: A harness (0290), 2 M harnesses (0292), 3 speakers (0207) or
• Coxed 8: A harness (0290), 3 M harnesses (0292), 4 speakers (0207)

Yes. There will be a 3rd harness called the Smart Harness which acts like a data cable for the boat. This harness would connect with individual Seat Displays connected to the oarlocks. All the oarlock data will then be streamed live using the CoxBox GPS unit. The streamed data can be automatically logged into the app when using our LiNK Logbook Team or Pro accounts which will be available shortly.

Please make sure you have a solid satellite signal lock before starting your row. The satellite icon will become filled-in when a satellite lock has been made. It is recommended to turn the unit on when outside and wait a few minutes for a satellite signal lock before rowing.

A charger and microphone are not included with a purchase of the CoxBox Core/GPS. If you do not have either of these items, you would need to purchase them separately in order to use the CoxBox.

No, the CoxBox Core/GPS will just ignore the rate sensor if connected. It is advisable to leave the rate sensor connector if you still plan to use previous versions of the CoxBox in that boat. If you are only using the CoxBox Core/GPS in the boat, the rate harness and sensor can be removed to have less wiring in the boat.

Yes. We will have an impeller that can be used with the CoxBox GPS so you can get either GPS or Water based distance and speeds

Date and time automatically sync when the unit connects to GPS satellites. Customers have the option to set the Time Zone and whether Daylight Savings time is on or off in order for the correct time to be displayed.

Yes, but the functions will be limited to updating the firmware. In order to Live Stream or upload data, you would need to have a CoxBox GPS.
