SpeedCoach® XL4

SpeedCoach® XL4

Overview

For the serious athlete, the XL4 offers a complete performance monitoring system that maximizes the effectiveness of your training and coaching, for less that the cost of a pair of sculls. The Speed Coach XL4 combines ALL of the benefits of the XL2 and XL3 models.
As an athlete, you get all of the benefits of monitoring your heart rate in the shell, together with the ability to transmit your performance data when you're working with a coach.
As a coach, you can be certain that your athletes are not exceeding or falling short of your intensity targets.  And you don't need two XL4's to transmit and monitor heart rate; the coach can use an XL3 unit so long as there's an XL4 in the rowing shell.
We're often asked by coaches whether they can monitor heart rate on more than one athlete in a crew. At present, NK can only guarantee interference-free readings for XL heart rate monitors when there is only ONE chest-belt transmitter within a 6-foot range of the heart rate sensor at any time. As a result, it is possible to use two monitors in a pair or double by placing the stroke seat sensor close to the stern end of the seat deck, and the bow-seat sensor close to the bow end of the deck. In larger shells, the monitors and sensors will need to be at least two seats apart (i.e. at 2 and 4 seats, not at 2 and 3 seats).
Within these limitations, each athlete you wish to monitor will need an XL4, heart rate sensor and chest belt transmitter. To monitor and transmit heart rate only, simply secure the XL units and sensors at each seat (we sell an inexpensive mount with no wires for this purpose). Each XL4 can be named with the seat number or athlete's name to facilitate review. As you page through the transmitted data in the coach's launch, you will see each athlete's heart rate on their data screen. If a unit is mounted on a full Speed Coach wiring harness, that unit will also transmit performance data. If you would like the athletes to have have access to full performance information on their XL units, you can install multiple wiring harnesses reading from the same impeller. This will also permit easier review of stored heart rate data coordinated with stored performance data for the shell.

Note: NK is continuing to develop technology that will permit use of XL heart rate monitors in multiple contiguous seats.

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.
