G5 GPS senso has been used in this watch. This helps you in tracking your speed limits. It gives you an awful lot of data like average speed, total distance covered, total mileage in km/h and mph.

Customer review:

[usr 4.5] I’m a data-driven person, and participate in running marathon. So when I realized I needed a heart rate monitor, I could only go one with a GPS receiver and could give me something extra other than the ordinary GPS heart rate monitors. I was also much against daily battery recharging and so I needed monitor that would take long enough between charges. It is then, that I settled for the Polar RS800 GPS G(.

The device seems to marry my interests perfectly well. I use the watch to cover approximately 40 miles per week in average, and its battery go that long before I can charge again. The armband proved to be too loose or too tight at times, but I’ve since found its best fit. And sliding the GPS unit, in or out of the armband, to charge is also easy.

The Polar RS800 has a charger cable similar to my phone’s cable, so I do have an extra one to carry around. I know that the device is chargeable while operation, but I’ve not tried this. I would really love to do this while training for my Seven Summits quest, so if you have already done that, you can let me know how it is like.

The Polar Trainer 5, software that comes with the RS800, has not been able to connect to Polar Trainer Website like the other versions I’ve used with other Polar monitor models. This is something that has bothered me, given that I’ve worked with FT60 and FT80 which connected very well with the website. As a matter of fact, I still use FT80 for my indoor workouts, and the software is just awesome as it helps me analyse my workouts and see my routes in Google Earth. Garmin Connect does not accept the imported RS800 GPS files as indicated by Polar.

I mark the training log not be included in the report to prevent them from being deleted from Polar ProTrainer calendar.

Even though transferring files from the sports watch to my PC is fairly simple, at fast I struggled since I did not know how to position the watch and the USB adapter. I realised that the transfer LED’s are positioned opposite the big red button, but I thought they were in the big red button. If you jumble in a few minutes you will find the right position.

The watch can be very tricky to fasten, especially for new users, since the band has lots of metal bits and two loops to pass the strap through. The elastic loops seem to stretch instead of sliding over the strap, posing a challenge.

The watch has a huge red “start” button, which is very responsive. Once pressed, it makes the watch to beep and guide you to the next step. There are also silver side buttons, but which require sufficient force to conform. The side buttons are designed this way to prevent unwanted constant presses.

Unlike similar watches, the G 5 GPS memory clogs up can only be manually and wholly deleted. In most models, there is a rolling over option. The watch display is not set by default to show altitude, so you have to do it yourself. The various calibration modes are also a problem, unless you constantly train in a particular area. Like in my case I reset it a lot because I train in two primary locations, at 10,000’ and 5,000’.

Nevertheless, you can still get the altitude data on Google Earth even when the altitude display is off. So it is only necessary to set the watch to display the altitude if you constantly want to know your topographical level.

In terms of locking satellite, the GPS G5 is better than the Garmin 305. The Garmin I had lost signal almost ? the time I passed through a narrow gap between cliffs, on the other hand the Polar sometimes also do but it has 1/8 chances of doing that. What’s more, it takes the Polar less than a minute to get locked to the satellite.

Before I start my session, whether I’m driving or walking to a trailhead, I press the button on G5 for a couple of minutes. When I’m to get started, I press the big red button to start the readouts and indicate the functionalities status. If everything ok, I hit start. If you are going to use altitude, you need to calibrate the watch before you click the red button.

According to me, Polar RS800CX GPS G5 is a four-star heart rate monitor. The watch has a few annoyances but that is not a big deal to me. I value sport watches based on functionalities, performance and user-friendliness. On this basis, the watch has been generally good and easy to work around. Yes, I hate these few issues, especially the rubber band strap, but the watch is cool and score high on other benchmarks.

However, I deny it a five star rating for agonizing altitude calibration, inability to sync ProTrainer 5 with Polar Personal Trainer website like other models do, for the sensitive big red button and the less sturdy rubber bands.
