Product Description

Amazon.com Product Description

Sigma Sport's digitally coded Onyx Pro brings preset and individually adaptable endurance and interval training ranges to the marketplace. The training zones can either be calculated in line with IAT (individual anaerobic threshold) or maximum heart rate. The detailed analysis of the training units is ideal for all professional and ambitious sports enthusiasts. A magnification function for improved readability and a new kind of navigation for intuitive menu guidance are innovations that characterize this Heart Rate Monitor. 7 memory locations, a lap counter (50 laps with average and maximum heart rate indications), a light and a battery change compartment round off the features of this precise heart rate watch.

The Onyx Pro's Marathon Functionality
The marathon function of Onyx Pro enables a runner to accurately check and evaluate heart rate and split times during a marathon. The runner can store the values every kilometer by pressing a button and analyze the individual heart rates and split times after the marathon. The marathon function has a memory with a total of 43 positions and is automatically aware that the last value stored only measures 195 m, not a kilometer (total distance of a marathon is 42,195 m). As well as the full marathon, the function is also set up for the half and quarter marathon distances. In order to be able to properly pace yourself, a speed table provides you with optimum guidance. It helps the runner to find the right starting pace and reach his/her set goal. Example: In order to run a marathon in under three hours, you need to run every kilometer in an average of about 4:15 minutes.

Digital coding explained.

Digitally Coding Explained
Sigma Sport's Onyx models are stand outs due to their digital, coded transmission. Through this technology users avoid wireless disturbances during group training known as "cross talk effect" in specialist jargon. At the start of training, synchronization takes place between the coded chest belt and the heart rate monitor. Consequently the watch only receives data from its own chest belt. The heart rate readings are converted into digital data packages and transmitted to the receiver in the watch. A time coding and ID procedure within Onyx models guarantees that data transmission is significantly more secure compared to analogue heart rate monitors.

Features:

• Digital coded transmission
• 4 Heart Rate functions
• 6 time functions, including countdown and alarm
• Training mode with 3 adjustable training zone
• Fit Test (VO2max Rockport Test)
• Lap Counter (50 Laps)
• 1 programmable endurance training module
• Burned Kcal
• Total values per week, per month, and since reset
• Memory for 7 Training sessions

4.0 out of 5 stars Works great in warm weather, June 22, 2008

This review is from: SIGMA ONYX Pro Heart Rate Monitor Watch (Sports)

Overall, this is a great product. The functions are easy to use and I like the multiple memory function.

I would rate if 5 stars if not for one annoying thing. The strap must be really wet for the watch to pick up the signal. That's no problem in warm weather, but riding (my bicycle) in cold weather, or riding an easy recovery day where I don't really sweat, the strap loses the heart signal. I have used heart monitors from two other brands (yes, one was the big "P" brand) and didn't experience this problem on easy days.

Losing the heart signal temporarily wouldn't necessarily be a problem, but what usually happens is it registers an abnormally high heart rate (like 205 bpm) when I'm trying to hold my maximum to say, 145 bpm. It's frustrating to read the data after the ride to discover you don't know what your maximum really was.

If you're the type who sweats a lot, or you use it in warm weather, it is worth 5 stars. Otherwise, it is a 3 star rating if you use it like I do.

5.0 out of 5 stars The perfect value., April 5, 2008

By 

Jay "Firemonk" (New Haven, CT) - See all my reviews

Amazon Verified Purchase

This is my fourth HRM and I have used/own other popular brands and models including Polar, Oregon Scientific and Reebok. Wonder why I have four, I think once you get in to the metrics world and actually observe that smart training has major impact and you strive for the perfect equipment and of course..Just because !! :)

Here is my initial product definition requirements (Note - I summarized what my needs are before I started searching for the right product)

1. Constant heart rate display with options to quickly check for KCAL burnt, Check time, Average HRM.
2. HR Zone and ability to customize the interval and zone parameters
3. Endurance trainer and preferably have the ability to customize own routine
4. Memory to store my workout data for future reference (Ideally the watch should interact with my computer but if the price point was an indulgence, then it should at least have workout summary in memory for at least a week)
5. Chest belt can be replaced easily
6. The product should have decent website and I can actually look up information and address issues
7. MOST important - I should be able to change the batteries and avoid paying over the cost of watch for maintenance (Case in point my POLAR watch - Great equipment but hate the fact I have to send a product that I paid for in full to service center to have it replaced and pay for shipping and battery which is almost 40% of the watch cost)
8. Finally - Price. I'm a value hunter and I wanted a midpoint between features and price and budget was $100.

The value -
1. All my technical requirements were easily met and I had additional features like "Custom name" - The watch displays your name.
2. I love the multi-line display and the functions are nothing but logical. The manual with it's tiny print and multiple language can scare people, [...]
3. Price - The seller I got it from through Amazon had a decent deal for 80 bucks and you surely cannot go wrong with the price point for the features.

The technical meat -
1. The chest strap and watch synchronization is perfect every time. Compared readings to my other heart rate monitors and gym equipment and it's right on dot.
2. User profile customization is neat (Gender, Weight, height and watch calculates your ideal HR zones)
3. Endurance trainer is a real test and love the fact it keeps me motivated. The custom program allows you to set your preferences like warm up time can be increased to 10 minutes or more and like wise for workout and cool down. Device supports monitoring by time, distance and HR threshold.
4. The interval training mode is perfect for weight training.
5. If you are in to Marathons, this model supports a 42k, 21k, 11k tracking with HRM and LAPS (50)
6. This model supports IAT (individual anerobic threshold) - Now whether this method of training is effective or not is a different topic but the device can help you focus on your training based on your max heart rate.

Final conclusion -
1. Sigma Sport Onyx Pro effectively offers same and more features at about half the price of it's rivals.
2. Online research indicates the company is based in Germany and seems have good market share in europe and is knows for it's HRM devices for Cycling.
3. The watch and Chest trap construction is durable and the device actually looks clean without crazy offroading looks. If I can get at least 3 years with an investement of 2 dollars for batteries every 3-4 months, I got my returns for the investment.

4.0 out of 5 stars Nice Product; REALLY POOR Documentation, April 24, 2008

By 

WLF "An Amateur Renaissance Man" (Maryland, USA) - See all my reviews

Amazon Verified Purchase

This review is from: SIGMA ONYX Pro Heart Rate Monitor Watch (Sports)

From the original review, I would now rate it at 2 stars.

Really like the product; very comfortable for 4-5 hours of wear and a comfortable strap...not that hard plastic that makes so many others uncomfortable.

But, the multiple language documentation is really poor. I just want to be able to set the time and my workout parameters...tell me how...easily, please!

It has become more frustrating as I wear the product. The buttons are confusing and it continues to drop the HR function to a lesser screen that I cannot access while riding, pushing buttons, swearing, and staying on course.

It would still be 5 stars if the documentation was readable and understandable.
