That statement alarmed me a bit. Glad there were only three paying divers and y'all did newbie dives. Do you know how to escape a down current like those found in Coz? Do you still have DAN diver insurance?
I haven't ever been caught in a downcurrent but my understanding is to get as close to the wall as you can, and if necessary swim sideways along it to get out of the current. I think the DMs here are real good about assessing the risk though.
The funny thing about the dives both yesterday and today is that the current was RIPPING even on La Francesca. Some of the fastest drift diving I've ever done in Coz. The island welcomed me back in style! But the DM knew what he was doing, there was no danger of getting swept away on these sites. I gotta hand it to the newbies today, they all did great on air and we still got a full hour in for each dive. It was quite an experience for them and when we were talking during the SI I made sure to let them know how well they did. I was honestly impressed - I was not at that level when I only had a dozen dives under my weight belt.
I have always had DAN insurance in the past but went with DiveAssure for the first time this trip, just to get some extra peace of mind with trip insurance due to the COVID requirement. But yeah, I don't dive without dive insurance!
