So if you want to know the effect of different training sessions. This smart feature tells you exactly what you need to know with a quick overview after the session plus more detailed feedback via your training file or polarpersonaltrainer.com. - Running Index, Running Index is based on heart rate and speed data measured during the run. It gives daily information about your performance level, both aerobic fitness and running economy. Improvement in running efficiency indicates improved economy of running performance. - Speed/pace and distance Speed (km/h or mi/h) is measured with G5 GPS 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. - ZoneOptimizer adjusts personal sport zones for every training session based on your current physiological condition. This feature gives you the right heart rate zones depending on your physiological state at that exact moment, making sure that the you are always training at the right intensity. - 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). - Manual Target Zone, 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%). - Compatible with polarpersonaltrainer.com via Polar DataLink for planning, analysing and sharing your training (mapping, online training diary, analyse your training in detail, Training Load is available in Polar software. When you transfer training results from your training computer to polarpersonaltrainer.com, you can follow your training load and recovery in the training diary. Continuous monitoring of training load and recovery will help you recognise personal limits, avoid over- or undertraining, and adjust training intensity and duration according to your daily and weekly targets. - 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. - Smart Calories, 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Color | Black | | Compatible with | Desktops | | Item display length | 4 centimetres | | Features | Waterproof | | Sport | Fitness | | Map type | Street | | Batteries included? | Yes | | Brand | Polar | | Department | Men's | | Manufacturer | Polar | | Item model number | 90042167 | | Product Dimensions | 15.01 x 15.01 x 15.01 cm; 371.95 g | | ASIN | B007UNF9U6 | ## Images ![Polar RCX3 GPS Heart Rate Monitor - Image 1](https://m.media-amazon.com/images/I/81yFPKKyw+L.jpg) ![Polar RCX3 GPS Heart Rate Monitor - Image 2](https://m.media-amazon.com/images/I/81RVSv-zH8L.jpg) ![Polar RCX3 GPS Heart Rate Monitor - Image 3](https://m.media-amazon.com/images/I/81jF9nOT1PL.jpg) ![Polar RCX3 GPS Heart Rate Monitor - Image 4](https://m.media-amazon.com/images/I/81c61KmCrCL.jpg) ![Polar RCX3 GPS Heart Rate Monitor - Image 5](https://m.media-amazon.com/images/I/614amzQztxL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant *by S***9 on Reviewed in the United Kingdom on 11 April 2013* Delivered in 3 days on free shipping so very happy with the seller.Brilliant heart rate monitor with separate GPS and synchronisation dongle included. Been on a few runs and uploaded to the polarpersonaltrainer website. GPS tracks brilliantly and accurately on the map and this ties in with altitude, speeds and heart rate.The only down side is that you don't get the GPS G5 armband included, only a belt clip, however I have just clipped this to the watch strap and it'll do until I get the armband. The GPS speed seems to lag by a second or 2 but to be fair the GPS sensor is on my wrist and waving back and forth like mad however it seems very accurate and I've had no problems with signals when in built up areas or around buildings.5 different training views showing 2 or 3 details covering heart rate, zones, speed, pace, distance, lap times, etc so there should be one that'll suit you.All in all, I've had polar before, am loving this and will be happy to recommend it to anyone. Well worth the investment. ### ⭐ Used product! *by S***N on Reviewed in the United Kingdom on 12 November 2013* The product I received had been used, therefore I never even tried it. I sent it immediately back, this seems to be the norm, as quite a few reviews state that they have also received a used item. What a shame as it looks good and from the reviews I have read it seems to be a good product. I find it hard to understand why Amazon think it is OK to sell a used product as new. This a very expensive piece of kit, I will buy elsewhere . ### ⭐⭐⭐ It stopped working after 5 days *by B***N on Reviewed in the United Kingdom on 24 September 2013* Its a shame as its a good product, but the hart rate monitor stopped working, so we have been in touch with polar who are sending us a new one. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/261761440-polar-rcx3-gps-heart-rate-monitor](https://www.desertcart.vn/products/261761440-polar-rcx3-gps-heart-rate-monitor) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
