I'm set up to take an Open Water Diving Certificate course with Big Blue Diving on Koh Tao.
Although, I've always been comfortable in the water, I'm a little bit leery of the 200m swim test.
I can swim 50m fairly easy and 100m with effort, but to get up to 200m I have to alternate the freestyle with backstroke laps. Does anyone have any experience with this at Koh Tao.
I know I need to ask Big Blue, but I don't won't to tip my hand too early.
Thanks.
