Unreliable BPM reader
on 22 January 2012
When running with arm swaying, heart rate on watch reads far less (upto 40bpm) than gym equipment. With outstretched arms e.g. on cycle, watch fails to receive signal all together and heart rate is shown as three dashes - - -
Complained to retailer but outside of their period for giving a refund.
Returned watch and transmitter to manufacturer with description of problem. Manufacturer returned watch and transmitter, as far as I could tell in exactly the same condition and without any comment or explanation in response to my submission.
Re-tested on 40min run at gym at 7Km/hr. BPM on watch approximated to BPM on treadmill for less than 30% of the time. When cycling with hands outstretched on handlebars, watch lost contact 3 times.
On another occasion for at least a quarter of the time, the watch read less than half the value showing on treadmill e.g. watch 49bpm while treadmill 100+.
Frustratingly, on the third use after getting it back from the manufacturer, the watch read BPM accurately throughout my exercise except for when on bike - armslength seems to be beyond the range of reception.
In these circumstances, it is possible to get a reading by holding the watch next to chest belt for several seconds, but having to resort to this on a regular basis inevitably leads to disruption to the exercise e.g. to arm swing rhythm when running or requiring a stop when cycling.
Two weeks ago, I wrote to the manufacturer again, but I have had no reply.
As this watch does not provide consistently accurate BPM readings, I cannot rely on it for exercising within safe BPM ranges.
Other niggles: At first I found it difficult to get used to, having not memorised what the buttons do, when exercising, often pressed wrong buttons and did not get expected results.
Bpm display font is large but thin and I cannot always read it without glasses, which I do not wear when exercising. Other icons on display are far too small to be visible.
Only data of most recent exercise period is stored, so if Heart monitor button is pressed it wipes the store and starts a new measurement.
