  • Body measurement features
    • Manual target zone – bpm / %

      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%).

    • HRmax (user set)
    • HRmax (age-based)

      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).

    • Polar Fitness Test

      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 OwnCode® (5kHz) – coded transmission

      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 OwnCal ® - Smart calories

      Polar OwnCal ® - Smart calories

      The most accurate calorie counter on the market calculates the number of calories burned. Calculation is based on your individual data: your weight, height, age, gender and the intensity of physical activity. Smart Calories are available in heart rate monitors and activity trackers.

    • HR-based target zones with visual and audible alarm

      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.

    • Average and maximum heart rate of each lap
    • Average and maximum heart rate of training
    • Automatic age-based target zone – bpm / %

      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 – bpm / %

      Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute (bpm) or as a percentage (%) of your maximum heart rate.

    • Polar sport zones

      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).

    • Polar OwnZone® – personal heart rate zone

      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.

    • Speed/Pace – current, average and maximum

      Speed/Pace – current, average and maximum

      Speed (km/h or mi/h) is measured with GPS, footpod, stride sensor or cycling speed sensor. Pace (expressed as min/km or min/mile) stands for the rate of speed. Pace is usually used in running. By setting a target pace, you can follow how fast you need to run in order to reach a certain distance in a predefined time.

Reviews

RS300X is rated 2.6667 out of 5 by 6.
Rated 4 out of 5 by from Great Monitor, Not so good strap. I've used and abused this model for about 3 years. About a year in I noticed some cracking in the band. Another two years later it finally broke. I have owned several Polar monitors in the past and never had this problem. I also used the receiver as my everyday watch, and wore it nearly 24/7 (even in the shower). Overall this is a good training tool, with some great features and I feel is a great value in the Polar product line up. I'd be more upset about the band breaking if Polar wasn't so good with repair and customer service. I can't complain with that at all. As a matter of fact I'm replacing my old RS300X with a new RS300X thanks to Polar's trade in program. I plan to use it ONLY for training and not as my everyday time piece. Maybe it'll last a little longer that way.

Rated 3 out of 5 by from Great features, wrist strap a dud This is the 2nd time I have had to send in my watch for service due to the wrist strap breaking. I have truly loved it but getting tired of sending it in for service just because of the wrist strap.

Rated 3 out of 5 by from Great Watch, Bad quality strap! I have had this watch for 3 years now, it has all the features I need to keep track of my workouts, my only complaint is the strap, which I have had to change twice because it keeps breaking.

Rated 2 out of 5 by from good watch, terrible after sale (wrist strap) The RS100, RS200 and RS300x black/orange models need to be returned to a Polar service centre for replacing and sealing as the wrist strap and case are a single component piece. I just call to the local dealer and they say that is too older so then can't do anything.

Rated 1 out of 5 by from RS300X loses HRM signal I've had the RS300X for a year or so and while it can generally detect the HRM initially, it loses the HRM signal every few minutes. I've tried every corrective action suggested by the manufacturer but none of them have resolved this problem. The HRM functionality is the reason I bought this watch, and without that functionality, this watch is useless to me.

Rated 3 out of 5 by from disappointing data recording and integration Works well, but the amount of dat it imports, and the polarpersonaltrainer platform are incredibly limited, and clunky. It is also very hard to integrate with other services. A OK starting HR monitor, but shows its age.
