Product Description

Manufacturer's Description

Body measurement features:

Automatic age-based target zone – bpm / %

To help you train safely and effectively, the training computer determines your heart rate target zone limits automatically according to your age-based maximum heart rate (220 minus age). The limits are determined either in beats per minute (bpm), as a percentage (%) of your maximum heart rate, or as a heart rate reserve (% HRR). See also Maximal oxygen uptake (VO2max) and Manual target zone.

Heart rate – bpm / %

Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute or as percentage of your maximum heart rate. Heart rate can also be expressed as a percentage of your heart rate reserve, meaning the difference between your resting heart rate and maximum heart rate (HRR = HRmax - HRrest). In Polar software or during strength training, heart rate can be displayed as a graphical trend.

HR-based target zones with visual and audible alarm

You can define your target zones for a training session based on heart rate to help define the right intensity. When you are out of the preset zones, the training computer will give a visual and audible alarm.

HRmax (age-based)

The highest number of heart beats per minute (bpm) during maximum physical exertion. For a rough estimate of your maximum heart rate, subtract your age from 220. HRmax is a useful tool for determining the intensity of training as intensity zones can be defined using HRmax. Some Polar products define maximum heart rate during the Polar Fitness Test, see also HRmax (Polar Fitness Test -based).

HRmax (Polar Fitness test-based)

Some Polar products predict your HRmax simultaneously with the Polar Fitness Test. This predicted HRmax value is more accurate than the age-based formula (220 minus age).

Manual target zone – bpm / %

This feature enables you to define the target zone as you want and is suitable for your training. You can set the target zone for your training as beats per minute (bpm), as a percentage of your maximum heart rate, or as a percentage of your heart rate reserve (HRR%).

Polar Fitness Test

Polar Fitness Test measures your aerobic fitness at rest in just five minutes. The result, Polar OwnIndex, evaluates your maximal oxygen uptake (VO2max). With the Polar Fitness Test you can measure your aerobic fitness by yourself, automatically and without any exertion. All you need is your training computer. The Polar Fitness Test is as accurate in predicting the VO2max as any sub maximal fitness test. The test is based on heart rate and heart rate variability at rest and personal information.

Polar OwnCal® – calorie expenditure

Polar OwnCal calculates the number of kilocalories expended during training. This feature allows you to follow the kilocalories expended during one training session and cumulative kilocalories expended during several training sessions. Some Polar products also estimate the fat-burning percentage (fat% on display), that is, kilocalories expended from fat during a workout which is expressed as a percentage of the total kilocalories burned.

Polar OwnCode® (5kHz) – coded transmission

Coded heart rate transmission automatically locks in a code to transmit your heart rate to the training computer. The training computer picks up your heart rate from your transmitter only. Coding prevents interference from other training computers.

Polar OwnOptimizer – personal training status

Polar OwnOptimizer feature is an easy and reliable test to determine whether your training is optimally developing your performance. OwnOptimizer helps you to optimize your training load during a training program so that you experience an increase in performance and do not undertrain or overtrain in the long run. Based on the test, you are provided with a scale and description of your personal training status.

Polar OwnZone® – personal heart rate zone

Polar OwnZone® determines your personal heart rate limits for a training session. Depending on the day and time, your physical state may vary, for instance, if you are stressed or tired, or if you are not fully recovered from your latest training session, Polar can determine that information from your heart rate and guide you to your ideal training zone for that moment.

Polar sport zones

Polar sport zones provide an easy way to select and monitor the intensity of your training and to follow sport zones based training programs. Training is divided into five zones based on percentages of your maximum heart rate: very light (50-60%HRmax), light (60-70%HRmax), moderate (70-80%HRmax), hard (80-90%HRmax) and maximum (90-100%HRmax).

Recording features:

Adjustable recording rate – 1s, 5s, 15s, 60s

The samples of your heart rate are stored either in 1, 2, 5, 15 or 60 second intervals. A longer interval gives you more recording time, while a shorter interval allows you to record more detailed data. A shorter recording rate uses the memory of the training computer up more rapidly, but enables more accurate data analysis using Polar software.

Totals

Totals includes your training data starting from the last reset enabling you to follow your long-term training.

Weekly history

Weekly history gathers your weekly training data. By selecting a week, you can review your training data for the week.

Training features:

Display zoom

Display zoom feature allows you to zoom in information on the display during training.

Graphical target zone indicator

This feature points out graphically on the display the zone you are in during a training session helping you to stay on the desired intensity zone.

HeartTouch – button-free operation of wrist unit

When HeartTouch is on, different training information during training can be accessed without pressing buttons, for instance, when gloves make pressing buttons difficult, by bringing your training computer close to your transmitter.

Time based interval timers

Use timers, for example, as a training tool in interval training to tell you when to switch from a harder to a lighter period and vice versa.

User configurable displays – all lines

This feature allows you to configure training computer displays to show the information that you need during your training session. Configure the displays either in the training computer or in ProTrainer 5 software.

ZoneLock

ZoneLock feature helps you to accumulate certain intensity. You can either lock a zone before a training session or during it by pressing a button when you are on the desired zone.

ZonePointer

ZonePointer is a visible and moving symbol on the training computer display indicating whether you are inside the pre-set target zone. This feature helps you to reach the desired intensity targets.

Watch features:

  • Backlight

    I have owned, I think, four other Polar HRMs before buying this one. I had expected a more sophisticated and capable HRm. What I got is some sophistication and a series of headaches.

    First things first. The unit is aimed at runners. I use it both for running and for training for mountain marathons. It is a neat, sleek looking device on a well-designed resin wrist strap. The chest strap is of the newer Wearlink design with a transmitter unit that clips into too press-stud type connectors. I have no problem with the chest strap design, although a glance at the Polar website shows that many people find if rubs and chafes in prolonged use.

    The watch unit can be set up in a variety of ways, depending on how you want to use it. It can be set to follow a pre-determined workout, moving its measuring range either at predetermined times or predetermined levels of intensity. I guess that works fine for people following a relatively similar routine time after time. I found it intensely annoying. What I wanted to do was strap the thing on, do my exercise [which varies day-by-day] then get feedback on time spent in each of my pre-set zones. It is almost impossible to do this, although the manual suggests it is easy enough to set up.

    One can set the unit so that it will determine your exercise zones, based on a brief workout which it monitors to produce the result. No use to me, but it could be a useful feature for some, as fitness improves.

    Ergonomically, I have a few problems with the wrist unit. Function buttons are mounted on the ends of 4 short protuberances at the corners of the display. This makes them easy to use while exercising, but very vulnerable to being accidentally pressed. I often find myself taking layers on and off.

    The previous reviewer has commented comprehensively on capability and learning to live with this product so I will only add a small point here.

    I am new to heart rate monitors and bought this model for its data logging capability, believing that any improvement in my fitness would be highlighted in the data it captured. At the time I had a Windows based computer but have now moved to a Mac. While the software worked satisfactorily with Windows, there is no support for Mac users, other than running Windows in Boot Camp or some similar product. I am waiting for a USB-IrDA adapter to arrive but am not confident that I will have any success with this. For a company of Polar's standing, I am dissappointed in their singular computer platform stance, as are many other users it seems. I see no reason why the software could not be ported to other operating systems.

    If you're a Mac user and need a HRM with data download functions, I advise you to look elsewhere first, or select a cheaper model and do without this capability.

    Excellent replacement for my Polar S625x just as functional plus advanced software for reviewing and analysing runs, and at a much cheaper price than I paid for my S625x 7 years ago.

    I've just bought this one after having the F92Ti for 4-5 years. The wristband of my former watch broke and since Polar has stopped support for the F92Ti, I had to buy a new workout watch. You will have noticed that I've gone from a fitness watch to a runners watch since I run now more than before.
    I've not come across anything wrong so far, it does what a Polar watch for runners should do: monitor your heart rate, give you information about the training and keep data for further analysis of your training pattern.
    If you compare my two watches, this one has a red button on the front which, as said by others, is prone to be pressed in even while putting on your coat. No big deal because I don't wear the watch when not running. So all in all, 4 stars for me!

    I purchased a Polar RS400 HRM through Amazon from Millet Sports....product arrived on time, well packed but to my surprise it doesn't include an infrared stick to allow the connection between watch and computer.

    This means that, as computers don't come with infrared ports anymore, I can't use the powerful software application that comes in the box. However, the pictures displayed by the seller include an infrared stick.

    I've emailed Millet sports to understand what has happened, their reply is just unacceptable (pictures are uploaded by Amazon, there is nothing we can do, if you want to buy a IR stick this is the link to our site).

    Bottom line....you need to add at least another good 35-50GBPs for an IR device that according to most of the reviews doesn't work well, or almost 90GBPs if you want one with good reviews.

    Never had such a bad experience at Amazon it it raises serious concerns about how capable they are of delivering what's in the product description.
