Hi guys, I have a related question about CO2 for the original poster Dave, who is a Meg ccr instructor. Maybe this is not the right place to ask it or I should post it as a new thread but here goes anyways. I and a buddy of mine both dive Megs. My buddy is fairly new to the Meg and has been using it for about half a year. He told me he recently went on a dive with some other guys and suspected he had CO2 problems during the dive. He completed the dive, but after he got to the surface he had a pounding headache the rest of the day, had nausea and actually threw up. Seems to be pretty classic CO2 problems.
He has dove his Meg since the incident a couple of times and not had any problems. We both took a look at his Meg, he went through the checklist, checked the O-rings, mushroom valves, etc … I think he said it was a 2-3 hour dive so he was within the limits of his axial scrubber. His scrubber material is not past the expiry date and is a brand used by many divers. We could not find any problems. He has an older Apeks 2.0 with many modifications, he bought used with an axial scrubber, a custom BOV, the loop looks custom and some non-ISC backmounted counterlungs. The custom mods he has made me a little leery but it looks like everything holds a seal. I told him maybe he had a one-time problem when he assembled the unit. Maybe on that dive one of the O-rings did not seat correctly, or maybe some junk got in his mushroom valves. Since he has an axial scrubber it is harder to screw up the packing of that scrubber than the radial one. I told him he just needs to be extra careful on the checklist and take his time. Do you have any recommendations? Fortunately I’ve never had any CO2 problems with my Meg. Thanks.
