Can I be totally honest here? This might be a bit brutal, so turn your head if you are easily offended - Many divers suck! Their skills are terrible, and they are headed toward disaster.  2 hours of lessons at a resort where there is clear water does not make you a diver. Frankly, that is where many of the tragedies come from. So, if you are thinking about doing that, DON’T! It is only a few levels above suicide. Diving is not difficult, but there are skills involved that absolutely cannot be learned in a few hours. It may look like you put a regulator in your mouth and just breathe, but it is far from that. Ok, so you did it that way and lived. Big deal, I pet a tiger once and I’m still here. Doesn’t make tigers safe. Have a problem even as shallow as 30 feet, mildly panic and shoot for the surface? If you weren’t thinking clearly and held your breath on the way up, the next time we would see you would be at the pearly gates. Well maybe not because only good divers go to Heaven. Gospel according to Freddy. 

If we train you then we would dive with you.  Our promise - even our basic training is well above average. Our Beginning Scuba course includes an additional Perfect Buoyancy course and certification! The #1 skill to master and we include it ($180 value).

We train you as if your life depended upon it, well…. because it does!  Last but not least, it should be fun and exciting. And hey, we are fun and exciting guys and gals! Don't take our word for it, check out these testimonials and see what our students have said.
