Polar A3 Heart Rate Monitor

The Polar A3 is a heart rate monitor that has been around for  a while now but it is still a well talked about heart rate monitor. One thing that is clear about the polar a3 is that is resourceful and durable. So now this monitor is old and cheaper but there are still things to consider if you plan on investing in this monitor.   

If the batter in your chest strap fails it will be impossible to get a new battery you will be forced to buy a new chest strap. I am pretty sure you could search and find batteries that are compatible but it would have been much easier if Polar sold the replacement batteries.  

The standard display on this monitor is your current heart rate. This display is very large so it I easy to read, also whenever you fall out or go above your optimal heart rate the monitor will make a sound to inform you of this. At any time you can switch the display to show the period of time you have been working out instead of your current heart rate. 

It is not uncommon to have your heart rate not registering or act erratically when you first strap on the chest strap for the a3. Once you start exercising and sweat a little then it will work perfect, some people on youtube advice putting a tiny bit of water on the strap before. However, I would recommend you do your own research before going that route. 

A heart rate monitor can really help you if you decide  to exercise, it will monitor your heart beat and prevent a lot of major illness if used wisely.
