Polar RS300X G1 Heart Rate Monitor Watch with G1 GPS Sensor (Black)

A smart, intuitive training computer for runners and cross-training athletes, the Polar RS300X G1 wrist heart rate monitor helps you to train at the right intensity with personal training zones. This version of the RS300X comes with Polar's G1 GPS sensor, which provides speed/pace and distance measurement for outdoor sports such as running or cycling. It's a great choice for those who mix up their training regimen with cycling, inline skating, paddling, mountain biking or hiking.


Combining heart monitoring, pace, distance and positio helps to improve a runner's efficiency. So from the technology point of view it is a great product!

The only thing I don't like is that all the accesories have to be bought separately and not all stores have all the accesories; a bundled product will have been a better option for me since it took me several transactions to get what I needed.

After reading the other reviews, I have just a few comments. This watch/gps works well for the most part. I have had several gps units, including Garmin, and they all EAT THE BATTERIES, they all LOSE SIGNALS in shady areas. The lower your battery, the longer it takes to connect. Some of the GPS watches come with an optional lithium battery you can buy. If that's an option for the one you have, I highly recommend it.

I have good quality rechargeable batteries which I swap out on all my GPS units right before walking out the door. I also always have spare batteries in my car and my backpack just in case I forget. It seems like a pain, but if you get into the habit of doing this you won't even think about it after awhile. And I guarantee you, if you change the batteries before each use, you will get good signal reception, except in shady areas.

However, once you are back in an area where the unit can get reception it "catches back up". So the fact that it temporarily will lose a signal is not the end of the world. I have a Garmin eTrex which I use for hiking and geocaching and horseback riding and it has the same issues - if the battery is low it takes forever to get a signal, when you are in deep shade you lose a signal. running watches with gps

 So overall, I am really happy with this unit - it works pretty much like I expected it to. And I was glad to get rid of my Nike+ stuff which never worked well for me anyways even after calibrating several times on a treadmill. This unit is way more accurate.

As far as uploading the data - yes, it's irritating that you have to buy a separate piece of equipment for this when usb works so well with all my other GPS units. But once set up, it's easy to use.

So, while not perfect, this is a good solid unit which does the job.
