So, what can I do? Of course compare it with a known altitude lor. Where can you find a place with a known altitude? Bukit Timah Hill lor, there is a stone with the altitude of the peak of Bukit Timah Hill ingraved.
I went all the way to this 'sacred' stone here. The height is stated as 163.63m. I took a reading on my Protrek 80, guess what the number came out? 165m! OMG, it is really accurate, just within the +/-5m accuracy as stated by the watch's manufacturer.
With this, I get a lot more confident about the altimeter's readings. Mmmh, this is before I bring this watch to the office, which is badly polluted by all the electromagnetic fields, from handphones, to computers, and the deadly magnets used in HDD.
Anyway, I am a lot more happier now :)
