OP
Tienuts:Sometimes, some guys just fall throught the cracks and make it to DM or above. One, I encountered called himself "Crazy Dan."
On a guided tour (5 divers) of a reef, Crazy Dan's dive briefing included the following "we will dive until the first person runs out of air. They you will share air, signal to the group, and we will all surface."
At least you know what your min air was ha ha ha. Zip
A DM at the shoal here one gave a briefing, 'We are going to get into the boat and dive, so lets go.' What she failed to notice was 3 Instructors on rebreather. With no max time, they had a 2 1/2 hour ball. When they surfaced, most other divers where see sick with a angry DM and skipper. They nicely pointed out that they where not told the max dive time. Needles to say when the same DM saw the group the next day, they had one of the most thorough briefings they ever had ha ha ha
