When you step up to the RS800G3 Heart Rate Monitor, you're getting the best Polar has to offer, plus GPS-enabled precision speed and distance tracking for multi-sport functionality. Lots of heart rate monitors and running watches can measure your speed—they use accelerometers to calculate your foot, arm, or body movement. But what if you're running a river in your ‘yak, flying down a mountain pass on your bike, skiing or snowboarding? The SiRF GPS technology in the Polar RS800G3 tracks you independently of your body motion, allowing you to ride, paddle, or pedal and still calculate how fast and far you're going. Not only that, the RS800G3 factors in tons of other info, like heart rate zones, altitude, ascent, descent, pace, elevation profiles, and more, all in comparison with each other and viewable on your computer for ultimate workout analysis.

Great monitor

I am a newbie with this watch, before the RS800 g3 I had had other monitors more simples, but after a couple weeks using the watch I can say:

Definitly, it is a great and fancy tool.
The watch looks cool and the rest of the implements are easy to set up.

The only issue I have found sofar, is the documentation, because was not easy to configure the GSP functionality at the first time, however, just looking for at the polar site, you can find the tips to activate the full functionality of your monitor.

In my personal opinion, this watch is perfect for the people that want to run long distance and keep tracking a lot of metrics to control your progress, distance, altitud, stride and things like that.

Finally, is a perfect tool to share via internet with your coach.

With the GPS 3

Not a great tool for Nordic Skate with the GPS 3:
1. The Polar Protrainer software shows a 22.5 mile distance.
2. The Curve at the Open exercise option shows 14.0 miles.
3. The actual distance is 14.0 miles at the place where I skate.
4. The reason for the discrepancy in distance, I don't know.
5. I reset the watch, just in case that was the problem. It didn't fix it.
6. The last eight (8) times I had the same problem. I tried different places.
7. It doesn't measure the accurate distance when using for Nordic Skate.
8. I measures the heart rate, the time, speed, and ascent.

This is supposed to track independently the distance from the body motion. It does not.

What comes with the RS800G3 ? The shown GPS only or also the Polar S3 Stride Sensor?

Responded on

Only the GPS, but it works very similar to the footpod sensor, I mean, logging the distance, and the other metrics.

Liking this watch, but no Mac support :-(

I really dig this watch... the metrics captured on each workout with the HRM and GPS combo is awesome. An hour mountain bike ride yielded 707 calories burned, 8 miles ridden with 1000 ft. of ascent/descent--great info to know.

I like that with the GPS I can also track my trail running adventures. The new G3 GPS offers solid satellite signal and provides great measurement throughout the workout. I've yet to attach it to my arm, but have found it to work well in my hydration pack and in my back jersey pocket.

It tracks everything you'd want to know about your workouts, but I can't take advantage of the software yet because I'm on a Mac and there's no Mac support at this time (drives me nuts). Aside from that, the watch works great... now to find a friend with a PC.

After 15 years, I'm switching to Suunto

I have had three of these watches. Long story; one I broke in the Army (not in a situation where it should have broken), one got badly scratched, and the third is also badly scratched. I started using Polar back in 1993, and have ALWAYS used a Polar HRM in my 23 100 mile races I have done since then. No one could compete. But now, two issues have arisen.

First, this watch just is not durable. It is designed for marathoners who will take it off except when working out. It is a "road watch." No rocks, sand or dirt allowed. Second, all of my 800s have had issues with communicating with the W.I.N.D. chest strap. I even bought some bah-bump cream to help out, and I still get wildly erratic readings in the first twenty minutes of my workout (tried all the tricks, spit, water, etc). 180 to 60 in ten seconds. Gah! Who needs that at the start of the Wasatch 100?

The older 600s and my wife's 625x is a better watch. Now that Suunto is a legitimate competitor, I am switching over. Can't sell the watches, but I do have two extra G3 units I'll eBay.

What comes with this package? Is there a place where I can find this information on the site. I have seen advertised both the RS800 and in other places I see it as the rs800cx is there a difference?

Responded on

This same watch can come with the G3 GPS unit or with the S3 footpod sensor. However the RS800 system are G3 compatible and you can buy it separately

I have uploaded a picture with all package, but anaway I will describe each one:

- the watch
- the gps sensor
- the monitor (you can change it, when the battery is out)
- usb infra red drive.
- two driver/program disc
- small manuals in several languages.
- one battery for your gps sensor.

Do I have to wear a strap around my chest to have this work?Is the G3 included?Is it water resistant?Ciao

Responded on

You only have to wear the strap if you want it to record you heart rate.The G3 is included.Water resistant to 60ft (20m).

Responded on

Additional comment to the strap. If you excercise indoors during winter, double check the compatibility of the strap with the treadmill / bikes / elliptics cardio sensor systems. Most of them aren't on the same frequency than this watch

Does the GPS sensor enable you to read utm coordinates directly from the watch?

Responded on

No, your coordinates are not displayed.

Responded on

No, but you can read the coordinates afterwards on the computer if you use GoogleEarth

Without reviewing the GPS

This is certainly the top of the line for polar, no doubt at all about that, but I find the use of the watch extremely cumbersome, even when done on polar performace 5 and then transferred to your watch.

The screen on these is VERY soft. Contemplate hard on going to or someplace similar to get scratch protective films made for it when you first buy it. Mine has a pair of huge obnoxious scratches on it from a car door.

The software does require some steep learning curves. You will have to manually delete a lot of heart rate spikes (there is a feature to do this; suffice it to say that a heart rate of 2000 actually does get recorded onto the watch.) Heart rate spikes are much more common than I expected.

The watch did help me in improving my fitness. For me, I will transition to a Suunto T6, and use Peak 2 Peak software instead, which is Mac compatible.
