To make things easy, might as well list all the local guys for you to contact and make a decision. In no particular order of preference.....

1. Singapore Freedivers. Run by Bernard Wong, he's been operating the longest in Singapore. (I think 3 years?)  Does AIDA 1 star in the pool (Local) and AIDA 2 star in Tioman/Cebu (overseas). He probably conducts courses in other overseas locations too.

5. Singapore Freediving Academy - These guys teach PADI, SSI and Apnea International courses. They teach weekday and weekend courses both locally and overseas and are probably the largest guys in SG atm.  They also run regular training sessions and overseas trips.

I'll be in Camiguin (near Cebu) in Feb to do freediving course with http://www.kurmafreedive.com/!
Let you know more when I get back if I can remember =x (and if you are interested! haha)
It's a 3 days WSF/RAID FREEDIVER course (theory available for you to do at your own time before the course) and costs PHP12,500.00
Don't really know the market rate, cos I didn't really research into it. Just planning for a trip to philippines and saw this option available, so I just jumped at it!

Heys! I'm back. haha, now a freediver under RAID.
Really fun experience! started with barely 1min of breath-hold and I extended it to approx. 2 min of breathhold at the end
Love diving but i'm quite wary in the water~ so it was a little hard for me to relax and go further down.
This certification is pretty much the equivalent of AIDA 2 star, which lets you go down to max of 20m.

Note: If you dive a lot and consider getting a divecom, do get one with the freediving function!

Hi,

Can share what was the total cost for the course and if we need to buy our own freedive fins or will be provided for the course.
i m pretty interested to take up free diving.

Almost same as scuba course price. Gears r included.

Thank you.
