We were diving with a group of five divers of yesterday in water temperature of 44 degrees at 80 ffw. The outside air tem was in the lower 80's, We had 3 divers using "cold water' regs and 2 divers using Sherwood Bruts. I/we think that both of the Bruts froze up. The first one "froze" very early into the dive, about 6 minutes, the diver using said that it started to become very dificult to get any air. So he aborted the dive.
The second one "froze" about 20 minutes into the dive. Her reg had the same symtoms, it became very hard to breathe off the reg. She continued to use the reg for her assent and said it got better when the water warmed. She also said that she has had this problem before in cold water. A few weeks ago we went to 108 feet in 43 degree water and her reg did fine, but we did not stay down long. (13 minutes)
On yesterdays dive there was no task load. The first diver is very new to diving so he may have been breathing harder/ faster than normal. The second diver is fairly comfortable underwater and was under no stress at that time of freeze up.
From what I understand about reg freeze up is that they usualy free flow. Do you think that the regs froze (atleast partialy) or was there another problem. Both divers dove the same regs in the same conditions the day before with no problems.
I would realy like to understand what went on yesterday. Any insight would be much appreciated.
