Sigma Onyx Easy

German fitness equipment manufacturer Sigma is not particularly well known among American buyers. However, they are fast becoming more popular due to their equipment which provides a high level of functionality at a low price. The Sigma Onyx Easy is an entry level heart rate monitor, providing all of the essential elements of a good training computer while costing less than many competing models. The package includes the Onyx Easy Fitness Watch, the chest strap for monitoring your heart rate, and a convenient handlebar mount for attaching the fitness watch to a bicycle.

Upon starting the Onyx Easy up for the first time, you will need to enter some basic data about yourself. From this information, the Onyx Easy will estimate two target heart rate zones as well as a maximum heart rate. The first zone, called the Fat Burner Zone, will be around 55-70% of your maximum heart rate and should be used for complete beginners as well as anyone whose goal is to lose weight. For serious training, the Fitness Zone should be used occasionally. At 70-80% of your maximum heart rate, this zone will help to improve the overall cardiovascular capacity of the body. Because the Onyx Easy provides these clearly defined target zones, the training process is made extremely simple regardless of the overall goal.

For an entry level unit, the amount of information provided by the Onyx Easy is astounding. At the press of a button, it can display the total time that you have spent training, the average time per session, the maximum heart rate attained, the number of calories burned, and the amount and percentage of time spent in your target heart rate zone. This data can be displayed in weekly or monthly formats, or as overall totals since the last time the watch was reset.

The Sigma Onyx Easy is highly recommended as a first heart rate monitor. In this price range, most heart rate monitors provide little more than real time heart rate. The Onyx Easy provides far more, and can be an invaluable training aid at almost any level in your progress as an athlete. The only possible drawback to the Onyx Easy is that the heart rate monitor uses a proprietary method of digital transmission; unlike some more expensive digital heart rate monitors, you will find that it can not be used with most gym equipment.

Sigma Onyx Easy:

• Monitors heart rate within two target zones that are extremely easy to comprehend
• Saves up to 12 months of historical data from your workouts
• Includes a convenient handlebar mount for bicycles
• Digital heart rate monitor transmission may not be compatible with the majority of gym equipment
