Features

  • 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)
    • 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 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.

      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.

Rated 3 out of 5 by from Not intuitive As with the original, you need to have the instruction manual handy to operate. Display too small.

Rated 2 out of 5 by from Loved it at first Had worn the old Polar 20 for years. Replaced it with a FT4 and liked it very much but....Only wore it a couple of times when a rash started develop under the belt. Wiped off after each use and washed the belt regularly (after 3 uses). Stopped using the belt and the results of a severe reactions to the belt still evident after 5 weeks!

Rated 1 out of 5 by from Do Not Buy This I had it three months and it died. I did everything - everything - Polar recommends. I also changed the batteries several times. They want you to buy a new chest strap for $20, but I did not end up doing that as, according to Polar, the strap should last 8 or more months. But the REAL tragedy is that I bought an FT7 with the hope that it would be a better watch. Guess what? At 4 months, it is almost dead. Yes, I washed it. Yes, I detached the device on the strap and soaked the strap before wearing. Yes, I changed the batteries. The only way it works at this point is when I have the watch no more than 1 inch from the chest strap. That's right, I have a watch hanging off of my stomach until I buy a NON-POLAR ITEM. Some people have luck with these watches according to these few reviews, but about half do not. You be the judge.

Rated 3 out of 5 by from Great...except for its random "bad hair days!" I have had this FT4 for approximately 4 years. I have used it on/off; most consistently using it for the past 10 months. It jumps all over the place with my heart rate at times. Also, and this part is the serious pain in the butt, the chest strap does not communicate with my watch immediately (even after adding water to the connection area) and so about 10-15-20-30 minutes into a workout it will come on. I am NOT kidding! One day it was so bad it only recorded the last 10 minutes of one of my rare runs and I was super disappointed. Is this caused by my chest strap battery---and if so, there is no possible way to get a new battery in there as I cannot even budge the seal. REI suggested I contact you to see about getting an older, but brand new chest strap for my FT4---not the bluetooth model, please. HELP!

Rated 1 out of 5 by from Like others have written this is my second FT 4. Happy with the first one. The second has been problems after the first year or so. Changed batteries a couple of time. I hand wash it in the sink after every use and occasionally wash it in the machine tied up in a sock. The display jumps around. This the most consistent thing about it. I use it in town and out in the mountains when mountain biking. Don't think it is outside interference. Best place to use with gym equipment. Last one for me. as a matter of fact I am looking for something that serves my purpose. That works.

Rated 5 out of 5 by from Still Using After 5 years! I am still in love with my Polar FT4 after 5 years! I've changed the batteries in the watch and the heart rate monitor strap about twice in this time period and it is still working great and looks like new! I use it during every workout, which is basically every day because I'm an athlete, and I definitely prefer it over my other daily activity monitor because it has the more accurate HR reading due to the chest strap! I also just love wearing the watch around because it is so cute and durable. Thank you Polar for such a great product!
