Equipment is not well looked after.
My wife and other divers had to change reg, or 1st. stage before got into water (luckily!)
At the end of the trip, the staff asked for a lot of tips in an envelope and gave it to the captain who checked inside in front of some guests.
One guide told us that he and other staff haven't paid well so had to rely on the tip.
He knew their equipment is poor as a price we pay.
Simply the company doesn't pass onto our money to the operator and staff enough.
