You can donate gas, there is a longhose which you can use. If your buddy/a diver needs gas you will donate... But keep in mind that mod for gas for cc and oc are not the same. Mod for ean32 on OC is 30 meter and cc is 15 meter. When doing a 30 meter dive in a mixed team, bailout in doubles for...

A single cilinder with bottomgas + a pony bottle with decogas is not redundant gas.

After finishing ccr1 I did a lot of dives with mixed teams (tech 1 and ccr1). There were almost no ccr 1 buddies at that time. And I had to build experience with my ccr. All my cave buddies were only oc cave divers. If I wanted to get experience / keep my overhead experience I had to dive with...

I guess it leaks at the piston head o-ring or piston stem o-ring. Take a closer look and try to find the source of the leakage . Examine metal and o-ring surfaces for any signs of dirt or scratches.

The bailout for Gue ccr 1 training is EAN32. Ccr1 training is similar to Gue fundamentals with a ccr. CCR 1 training is without a stage, and only the ccr and doubles. With the gue configuration bailout in the doubles is also the diluent. Mod for ean32 as diluent is 15 meters, mod for 21/35 as...

Tech 1 is a prerequisite for GUE ccr1. When gue ccr1 is finished max depth is 30 meters / 100ft and no deco. Deeper dives and deco are permitted once 25 ccr dives have been completed (maximum depth 51 meters/170 ft depth, maximum 30 minutes deco and maximum 200 minutes scrubbertime).

There is no deco limit for cave 2. The max depth is limited by tech certification. Cave 2 + tech 1 depth limit is 51 meter, but there is no deco limit, it’s even allowed to use ean50 and oxygen n the same dive. GUE cave 2 without tech certification is max depth 30 meter and no deco limit.

Mod for 21/35 is 30 meter as dilluent for GUE ccr divers. The mod of 18/45 when using as diluent is 45 meter for GUE ccr divers. My GUE ccr doubles contain 15/55 which has a mod of 60 meter when using as diluent.

Het laatste half jaar heb ik weer het nodige gedoken. Ik ben benieuwd of andere ook hebben gedoken. Hier zijn wat video’s van dit jaar van mij.

For me it was worth the money.

There is no need to upgrade, the service kits are the same. I suppose I have over ten seconds of scubapro and Apeks. Tx50 I bough in 2005 and I still use them. There is one at my sidemount kit and one at my gue jj ccr. I never had an issue with my tx50 second stages.

Team bailout versus individual bailout. The calculation for the agency is the same, but the sac is different (20/25/30 liter/minute). The time which is reserved to solve a problem is different (1/5 minute(s)).

That depends on the agency...

I did padi open water training in 2004, something was wrong with my instructor, he probably didn't pay any fees. I've never received my Open Water Card. Once I got in touch with Padi, they blacklisted him. I had to repeat open water training at another padi instructor and had to pay again. I...

Have you taken gue ccr training ? I did gue ccr1 with my Uwatec TEC 2g in gauge mode. I did use my Uwatec for ascending (time and depth). My JJ ccr petrel2 was just my JJ ccr controller, but I didn't use it for ascending. I also know buddies who have done ccr1 with perdix in gauge mode.

I did one tech 1 dive with a failing computer. It was a trimix dive to 51 meters with ean50 as decogas. I had a computer failure with a team of three divers, it wasn't a big problem. I also did a 30 meter deco dive with oxygen as decogas. I had a computer failure in a team of 2 divers. That was...

https://www.gue.com/diver-training/gue-instructors/instructor-resume?id=4935 Antonio is a great instructor, I did travel to Egypt (Sharm) for ccr training, and it was worth it. I don’t know exactly what kind of training you want to do. But maybe Antonio could offer you training, or he...

sorry I did post in the wrong topic

I was using a 38 lbs wing. I did use 2x12 liter steel tanks (backgas ean32) and 3 aluminum stages, (2x 11 liter ean32 and 7 liter oxygen). The 38 lbs wing was fully inflated and just enough to keep my head above the surface with 5 tanks. At the end of the dive the tanks are neutral or even...

It would be better to talk to real divers at divespots in the Netherlands and ask their opinion, then ask for advice at scubaboard. The name(s) of GUE instructors people are promoting in this thread are not the same at the names I hear at the divespots or my buddies are telling me. Every (GUE)...
