Amazon.com Product Description:
The affordable, entry-level Timex T5G941 is great for those just starting out with heart rate monitoring. This digital wristwatch-style monitor continuously tracks your heart rate via a comfortable, elastic chest strap (which fists chest sizes from 25 to 53 inches). The large, easy-to-read display recalls your activity time and average, peak, and minimum heart rate, and it includes 12/24 hour time and month/date display. It also features INDIGLO night light backlighting for use at night, up to 2 years of battery life, perforated rubbers strap, and water resistance to 30 meters (100 feet)--enabling it to withstand splashes and accidental dunks into the water, but not suitable for swimming.

Rating : - Timex Heart Rate Monitor
This is the best heart rate monitor I have ever owned. It has features that the more expensive monitors don't offer for the price. You can replace the batteries on both the Timex wrist watch and the chest band, something you can't do on the more expensive brands (on the expensive brands, when the battery dies on the chest strap, you throw it out and purchase a complete new set)
Better yet, the Timex chest band works with the wrist watch of the expense brands (I'm not sure why you would want this because the Timex wrist watch has more features).
From now on, I'll buy only Timex Heart Rate Monitors!
