DIN got it exactly right. There are at times more than 1000 divers here and each and every one of them wants to dive Sipadan only. Only 120 divers are allowed to go there each day however.
The only way for the registered Sipadan operators to give every diver an equal chance of diving Sipadan is by packaging it together with some other islands. Every operator uses a different system to allocate the Sipadan permits but the bottom line is always the same, the more days you dive the more often you'll get to Sipadan.
At Sipadan Scuba we use an online system so we can actually guarantee your Sipadan days. You'll know exactly on which days you'll get to dive Sipadan right from the moment you make the booking. We also have 3 specialty courses that are being conducted at Sipadan: the PADI Nitrox, PADI Deep and PADI Cavern Diver
If Sipadan Scuba is fully booked to Sipadan on a specific date our online system will let you know that when you try to make your booking. That way you can try different dates to find availability, just like when searching for flights from eg. Singapore to KL on AirAsia or Tiger.
Each operator has been allocated a specific number of permits to Sipadan. If one operator is full it doesn't necessarily mean that all operators are full at a specific date. Always try to avoid peak travel periods to dive Sipadan more often.www.sipadanscuba.comwww.sipadanonline.com
