The Sport Kit uses an accelerometer that tracks a user's running or walking motion with 90% precision out of the box, and around 97% precision once calibrated by the user. Combining that new piece of hardware with new software and your personal data (weight and pacing over 400-meter walks and runs), it can make "close-enough" calculations as to distance, pacing, and calorie burning accomplished during timed or open sessions. In our initial uncalibrated testing, which has been confirmed by reader reports, the Sport Kit was occasionally off by as much as the expected 10% on distance, but mostly within that margin; calibration produced more accurate results.

On the other hand, pairing of the two devices was almost always quick and painless, accomplished with only a minimum of effort: the iPod tells you to walk around to activate the sensor, and within seconds, the workout is ready to start. Only once out of 30 or 40 times did we have an issue establishing a connection, and it was resolved by simply unplugging the receiver, then reattaching it. According to a new Apple FAQ on the Sport Kit, the sensor and receiver use "a proprietary low-power 2.4 GHz radio protocol" to communicate with one another, which the company points out "is not Bluetooth or Wi-Fi." A contact informed iLounge some weeks ago that the proprietary 2.4 GHz protocol was a limited, small stack variant of a more commonly known 802.11 wireless protocol. Despite the fact that they share the same 2.4 GHz radio spectrum, Apple's new FAQ notes that it has tested and engineered the Sport Kit to ensure that it will not interfere with existing wireless phone, cell phone, and Wi-Fi networks.
Notably, the Sport Kit's sensor contains a non-replaceable battery that has a lifespan of over 1,000 active hours, and will alert you when roughly 2 weeks of life remain. The good news is that you'd have to be a serious but slow runner or walker to use up the battery within two or three years of the Sport Kit's purchase. The bad news is that when the sensor's battery dies, it's not replaceable, so you'll need to buy a new Sport Kit. Few iPod accessories have a built-in expiration date, and given existing consumer complaints about this aspect of iPod hardware, Apple really shouldn't be going further down this road.

Daj sliku samo tog uredjaja (ako smes). To ne bi ni stalo u patike a da ne smeta, a tek da se jos stavi "poklopac" na njega?!?! Yeah, no.
