My ancient Polar Fitwatch is giving crazy readings even after getting a new transmitter belt. When any kind of wind picks up, the readings go off the scale. I thought it might be interference from my Trek Incite 8i wireless computer but trouble shooting has ruled that out and anyway, everything worked fine a couple of months ago.

Conclusion: it is fuggered.

I am on a budget (under £40) and need a basic HRM that will not suffer from any cross talk from other wireless devices. The Sigma Oynx Classic meets my needs nicely. Anyone have any experience of these devices, can they stand up to wind disturbance when descending at over 40mph and does the coded transmission mean that the receiver wont go nuts even with non-coded wireless cycle computers present?

Any other products/suggestions under the £40 mark?
