The T31 is the standard Polar chest band heart rate transmitter. It is also available in a package with Polar wrist band heart rate displays such as the Polar F4, F6, F7 etc.
If you work out in a gym equipped with modern treadmills, cross trainers, steppers, cycle exercisers etc you will find that the machines are all capable of picking up and displaying the heart-rate signals transmitted by the T31. So if you only work out in the gym using modern exercise machines (e.g. Technogym) just buy the T31 at less than half the price of the full transmitter and monitor package. If you later decide to use it for running, cycling or swimming, just add a Polar wrist band monitor.
The T31 is good value for money, in my opinion. Just ensure that the two conductive strips (look like carbon fibre) on the inner face are slightly damp before starting: once you get into the calorie burning zone your perspiration will keep them that way!
For anyone having problems just remember to wet the hatched areas that go against your skin. I give them a quick lick which does the trick.
However on the treadmill my HRM was detected on treadmills both sides of me and I also found the connectivity and measurements were erratic - this could be due to the fact that the HRM was trying to connect to other equipment near by. I would recommend paying a bit extra and buying a coded one.
Also you cant changed the battery on this. When its dead its dead - however you do get 2400hrs / 5 years of use
I should add that the battery to the receiver of the model that comes with the T31 can be changed but the manufacturer recommends that the product be taken to an authorized repairer to effect the change. I managed to do it myself but it wasn't easy and there were no instructions in the product manual. Again, this is very bad policy and quite anti-consumer. Again, more expensive models are describe as having batteries that can be replaced by the owner. This is bad. I expect better of a Scandinavian manufacturer.
