The Polar RS300X works well. But the footpod is a little bulky compared to some others I’ve seen (specially the Nike+ one). The monitor has a lot of functions, but during workout is somehow difficult to read, as the numbers are thin and small, specially the pace. During the night it becomes really hard to use.

I’ve been running for the past two years and I’ve been using a heart rate monitor most of that time. I always wanted a Polar but for one reason or another I ended up with other brands. This past weekend at a pre-race expo, I came across the Polar table and decided to take the plunge. I haven’t been disappointed! I ran in my 5K the next day with the footpod on and the level of accuracy without calibration was impressive. For the 3. 1 mile race, it said I ran 3. 26 miles. Given that I was not running a straight line due to the crowds, I figured this was actually very close to my true distance. When I finally got to calibrating it, I discovered that it was about 0. 04 miles over per mile. Obviously not GPS level accuracy out of the box but good enough to use without doing any set up. Now that its calibrated, it measured within 1/100th of a mile.
I’ve started to use the OwnZone feature that Polar built in and it seems to be very smart. I’ll be interested to see how it guides my intensity over the next few months. The OwnZone measures your current physical state and recommends a range to train in. I’ve been running hard for the past few days and it recommended a pretty low intensity today after my warm up. Earlier it had recommended much higher levels of intensity so it appears to be doing its job.
The decision you have to make with this watch is if you want it with the footpod or the GPS and for my money I wouldn’t trade it for the GPS. A GPS is great if you want precise distance measurement outside. You will know exactly how far you ran. Battery life is an issue and if you train indoors or do any trail running you may run into problems with GPS signals.
The footpod, on the other hand, trades accuracy for flexibility. The GPS can’t give you as much useful information DURING the run which is more important to me. A GPS has a fairly long lag time when it gives you stats like speed. If I’m trying to keep a certain pace while I train, the footpod will tell me immediately how fast I’m going in real time. A GPS simply can’t do that. Also if you want to run on a track, run indoors, or run on a trail, the footpod is going to serve you very well.
The amount of data that the watch provides could be overwhelming if you’re new to HRMs. Even though I’ve been using one for a while, this Polar provides far better data than my original Timex and Suunto t3c did. The Suunto is close, I’ll admit, but the Polar’s ability to record how long you spent in all 5 training zones during a workout is pretty key. Whether you choose the GPS or Footpod version, the HRM itself is a very good mid-level device. Unlike other HRMs I’ve had that simply tell me what I’m doing, Polar actually tells me what I should be doing.
I’m also very happy with the ability to sync the watch with Polar’s training website with the FlowLink that I purchased seperately. It captures all of the information off of your watch and displays it in easy to read charts and graphs. With the ability to create training plans right there, its a great package.

I have given to this product 4 stars only perché no other the avévano still examined and the didn& #039; the t it wants to put the kabosh on it when it is concluded me on the restitution.
I have bought this product with the making models competition from Garmin, Timex and Suunto. I have intentional to control & #039; em all outside and I have found for/against to everyone. At the end, they have gone with the Garmin and much happy one I have made. It tries my review là (releases over my name in order to see mine other reviews).
Polar è un' company of physical form and the training excel in the generation all little ones and of the many senses to defy themselves and to measure your progress, or on the vigilance in itself that accompanying the software/Web site.
The vigilance in itself was the pià ¹ small of the four that I have examined, than good è for me from I& #039; m. a gallon and not necessarily to try a clunker. But, polar not è un' company of the vigilance and extension in their design of outlandish person. I wish that it has observed hardly a little pià ¹ watch-as and less like the sure foreign implantations that they have cad they give from a vase of Vulcan.
Nevertheless, I could go with the polar one, but what has killed l' transaction for me was l' unità of GPS. I have decided that I really have need of the GPS for l' pursuit where I& #039; the VE be and how far I& #039; the gone VE. There are two problems with Polar& #039; solution of s GPS:
- the implantations: Polar& #039; s the GPS è un' unità separated tied to your arm that contains three batteries of the AAA that works from spremuta after 8-12 hours. It& #039; pig of the battery of the S.A. That GPS è un' unità of thirds party that are use of the Timex that polar, così they& #039; with reference to the same ones. The hatch of this small what of GPS of the plastic era so as to close hard – me and an other critic has had a similar problem with l' unità Timex-stamped – nearly nixed it for that problem alone. Così, blow or lack on the fabrication. The è problem that unloading and recharging the batteries every little operations will obtain of being a controversy. And, seemed the normal foolish operation già ¹ the road with that thing on your arm. L' unità of it contains it to Garmin all to right all' inside of the vigilance in itself. Advanced Così.
- the software: If you& #039; king interested in downlaoding (uploading) your training in your PC and nell' to analyze to your miles totals, the calories and really to see your route covered on a program, richiederà many points for you and a small PC of good sense to make it with the Timex and the polar solutions. The didn& #039; look of t even to Suunto& #039; s, perché their solution of GPS had exited from mine wraps of price. Garmin& #039; the software of s easy è così – my review reads and you& #039; the ll it sees.
But, if you are really in your series and rep and objectives and objectives, or già well with other polar products, this is probably that one of right for you.

Pleasant, light, with the good characteristics but I make not understood because it& #039; s not compatible with polar software. Large against for me.

This large è vigilance, it dà the time, the distance, the step and the calories. This vigilance works for the every day training to the long operations of training – large è!
