Tells Time Too
In addition to checking your heart rate during exercise, the S410
heart-rate monitor can predict maximum oxygen consumption,
calculate calories burned and determine a target heart rate. It
also measures altitude and air temperature. Polar, 800-290-6330;

Boundless Balls
Always wanted an official NFL ball with your name on it?
JustBalls.com engraves your name--or the logo of your choice--on
a variety of balls. A personalized official NCAA football is
$89.95. Other balls range from $14.95 (baseball) to $99.95 (NFL
ball); www.justballs.com.

Serve and Pulley
In the Wilson Rollers 3.6 racket ($279.99), the strings are
secured with so-called rollers, which resemble little metal
pulleys, allowing the strings more movement. According to Wilson,
that creates a stronger trampoline effect and extends the sweet
spot from the center of the racket head to the edge. Call Wilson,
at 800-946-6060; or go to wilsonsports.com on the Web.
