• Fitness test: Use it to check your fitness progress periodically.
• Basic time keeping: Time, date and alarm
• Backlight
• Button tone: If this is switched on, you get a beep when you push a button.

The Sigma Sport Onyx Fit defines three heart rate zones as follows: 1st HR Zone (55 to 70% of HR Max), the 2nd HR Zone (70 to 80% if HR max) and the 3rd HR zone (80 to 100% of HR Max). The watch can calculate these zones for you automatically. Of course you can always set your heart rate training zones manually.

Here are the 3 types of training you can do with the Sigma Sport Onyx Fit heart rate monitor:

Free training: You train for as long as you wish and you train within the 3 heart rate zones in any way you please. When you cross from one zone to another, you will hear beep(s) to alert you of it. At the end, in addition to the overall info (see list item above), you can view the following:

• Percentage and time spent in each of the 3 heart rate zones
• Cool down heart rate information (optional)

Lap training: You can record laps with this feature. While out running, you can now record your time for each individual segment of your run. You can now measure your lap time every 400 meters or every mile or whatever distance you choose. You can mark up to 50 laps and you train within the 3 heart rate zones. At the end, in addition to the overall info (see list item above), you can view the following:

• Percentage and time spent in each of the 3 heart rate zones
• Your average lap time and time of your fastest lap
• For each lap, your average and maximum heart rates
• Cool down heart rate information (optional)

Training program: Here you specify a training duration and training heart rate limits. You can optionally include a warm up phase and a cool down phase. Even for these phases you can specify training durations and heart rate limits, giving you full and precise control over your training. When you have finished, in addition to the overall info (see list item above), you can view the following:

• Time and percentage spent in your (workout) heart rate zone
• Times spent in the warm up and cool down phases (if you use them)

As you can see, this is all very detailed. With the Sigma Sport Onyx Fit all you would want to know is here for you to analyze!

The Fitness Test involves you doing a 5 minute warm up, followed by a 1 mile walk. It then gives you the following results: Fitness level, estimated VO2 max, time, heart rate at the end. You can do this test about once a month or so to see if your fitness has improved.

The Sigma Sport Onyx Fit comes with 2 independent stop watches. The first stop watch is the one you normally use when you are training. The second stop watch is one which you can use separately to time the duration of something else (whatever it is that you need). A countdown timer can also be used to specify a precise duration.

Summary

The Sigma Sport Onyx Fit is a great heart rate monitor offering a host of training features. There is also no lack of training information available at your disposal for your analysis and future planning. It is also relatively inexpensive for what it is.

This takes you to Amazon for some of the best selections for this model. Certain selections come with FREE Super Saver Shipping.
