Overview

As a coach, you work really hard to figure out what it really takes to make your crew faster. No matter what, on some level it's guesswork. NK has changed that with the revolutionary Speed Coach XL3.
The Speed Coach XL3 incorporates a powerful digital spread spectrum transceiver capable of sending and receiving all of a crew's performance information in real time, up to 400 meters away. Buy two Speed Coach XL3's—one for the shell, and one for your launch—and you'll be able to see your crew's speed/pace, distance, time, average speed/pace, stroke rate and stroke count updated on your coach unit every stroke, in real time.
Add more XL3's for other boats and continue to monitor them with just one coach unit—you can page between data screens for up to 9 boats in your network. (You can assign each boat a 5-character name to facilitate review.) To monitor more than one crew without changing screens, or to allow other coaches to monitor the same crews, simply add more units to act as receivers. Advanced network security ensures that only you see the boats in your network, and that there's no interference between XL units, even on busy rivers. 
The Speed Coach XL3 has all the other features and capabilities of the XL1 model: customizable display, programmable workouts, extensive memory, computer upload with the optional interface, backlight and rechargeable batteries. (Fully charged batteries will provide 8 hours of use while transmitting/receiving.)

Multi-Country Availability (XL3 and XL4 Only):

In the USA and Canada, the FCC regulates the frequencies available for the technology employed in the XL radio units. We're limited in our capacity to provide these products in other countries by the regulatory bodies in those countries and the frequencies they have made available. At present, we have XL3 and XL4 models for USA, Canada and Australia. We have models in development for shipment Fall 2006 for Europe (including the United Kingdom).

These models are likely to less resistant to interference when two coach/boat networks overlap within their range, and also to be somewhat more expensive than the US units due to the costs of complying with additional regulations. New Zealand remains a possibility in the future as well, but we have no word on the availability of approved radios for other regions. We apologize for disappointed expectations in these regions, and will continue to work to these areas online as soon as regulations permit. These limitations do not affect the XL1 and XL2 models which will be available world-wide.
