Do I need a heart rate monitor and GPS watch is a question we are getting increasingly asked. In this show we dive into the various uses of these devices, their pros and also their cons. I talk about a few different models that are on the market and what you should be looking out for if you are going to buy one. Personally I have had a heart rate monitor since Polar launched the Polar Favor when I was about 13. I have used devices from various brands over the years and recently moved over (or back) to Suunto as my device of choice and the Baro 9 with its mind blowing a never before seen 100 hours of GPS time.
