Its very expensive, the cheapest outfit I have found is $175 for 2 dives in the Houston area. After tips that comes out to almost $200 for the day. That’s why I’m trying to find a boat owner that dives, we can pay him something cheaper, hell I can settle for $100-125 a day. Next two weekends I’m not available for diving, but the weekend of Nov 8th I should be. stay in touch
