I first got certified there 9 years ago, on the northern side
(the jetty side) ... we swam outwards in waters with really really
bad vis and had to find our way back to one of the anchor buoys
with our compass ... the thing is that the current would come at
you sideways, and because the vis was so bad, you wouldn't realize
that you're drifting very fast sideways ....
and the currents there can be killers ... over the years there were
several times where we had to abort dives because the currents were
simply too strong ...
the funny thing is that local divers seem to hold it to be sort of
a distinction to be locally certified, there's this "if you can
dive in Singapore waters, you can dive anywhere" mentality
....
well ... I last dove there in 05', and now I tell people, don't
bother, get yourself certified over a weekend in tioman or aur,
there's nothing left to see in Singapore waters anyways, and diving
in longkang waters may just turn you off scuba permanently ...
RIP to the chap ....
