I'm looking to buy a new Heart Monitor. Does anyone have any particular one they would be happy to recommend? I've been using a Sports Instruments Circuit 3 for the last couple of seasons. It doesn't have an average HR function which i would like. Also, my resting HR drops down to around 34 when i'm race fit and the Circuit 3 doesn't read below 40, so it was never any good for taking my RHR.
