Adventurer heart rate accuracy
More of a complaint than a query, but I'm bitterly disappointed with the consistency of the accuracy of the HRM on the Adventurer. It is accurate about half the time, which means it is inaccurate about half the time. Grossly overstates the HRM, by which I mean by 30 - 50BPM and more for considerable periods. It is not a problem of just warming up to find a strong reading, but can happen at any time including mid-run. I've tried wearing it looser and tighter, soft re-sets, hard re-sets, factory re-sets, left wrist, right wrist - nothing improves it. TT customer service tried to help including recommending wearing it on the underside of the wrist, contrary to the manual's instruction not to do so! It wouldn't be so bad if the HRM data was just for fun, but it was the largest reason I got the watch. The effect is that I can't trust the calorie count, VO2 improvement or heart rate training zones, plus anything else reliant on the HRM calculation. It turns out I could have got a chest strap then downloaded some free running apps to my iPhone and saved myself a couple of hundred quid. If anyone is thinking about buying this watch, I would advise thinking again.
