Coming back in 3 weeks, looking for dive location that Carlos is now working, (Carlos used to work for the police) . Last March he was working at the location at Wet Willys. Have enjoyed his expertice for almost 10 years. Also need to know if Naui open water testing is an issue, Boy friend has done all the pool and class work, just needs to do the referral test. What do we need to bring with us? Thanks
