    Scuba accident in a swimming pool close to my house

    For hydro, the tank is tested without valve. The owner or shop installs the tank after hydro.

    Dat wordt inderdaad sparen vrees ik. Zo gaat het meestal als je iets nieuws als een scooter of rebreather probeert… Er zitten veel voor en nadelen aan een rebreather. Eigenlijk is ccr en oc duiken totaal verschillend. Deco, gas planning, gas keuzes, failures, skills (bijvoorbeeld scr mode) enz.

    DIR- GUE Why are non-GUE divers so interested in what GUE does?

    There are gue ccr1 instructors who are telling that cave 2 + ccr 1 is enough for cavediving with rebreather. There are also gue ccr1 instructors who are telling gue ccr cave is required for cave diving with rebreather. Gue procedures are not clear. (There is no gue ccr cave instructor in Europe.)

    DIR- GUE Why are non-GUE divers so interested in what GUE does?

    :) I do not agree, scr mode is not learnt during gue CCR1. I think it should be required for cavediving with rebreather. I did spent a lot of time during iantd CCR cave at cave planning. I did not learn anything about caveplanning during ccr1. I know a lot of GUE divers who are doing ccr cave...

    DIR- GUE Why are non-GUE divers so interested in what GUE does?

    People are collecting cards and combine al their cards. If you want to dive with oc it would make sense to do oc dpv training. If your goal is dpv diving with a rebreather, you should do the training with a rebreather. I've seen diving gue divers a cave 2 and JJ in caves because a gue...

    DIR- GUE Why are non-GUE divers so interested in what GUE does?

    No, it’s not Kiril it’s an gue instructor who is doing a internship for cave ccr. Doing dpv cave oc doesn’t make sense for me. It’s harder diving a rebreather then diving oc during a dpv dive. With the jj you have to dump gas from drysuit, wing and rebreather. Trim and bouyancy are easier when...

    DIR- GUE Why are non-GUE divers so interested in what GUE does?

    And sometimes it doesn’t make sense what gue is doing. I know divers who were diving a JJ. The did dpv cave in February this year. They had to dive oc. After the training the were doing cave dives with the JJ ccr with the gue instructor. In October this this year they will do gue cave ccr with...

    Dutch scuba fans?

    De foto's zien er goed uit, de duiken zullen wel geweldig zijn geweest :-) Nuttlar vond ik wel leuk, maar Felicitas vind ik zelf leuker, ben je daar al een keer geweest ? De Oosterschelde blijft super, het zicht valt soms (behoorlijk) tegen, maar de hoeveelheid leven en de het uitzicht boven...

    CO2 build up during 65m (210 ft) dive.

    I wasn't there when you made the dive. But I also had CO2 problems, maybe it was caused by same problems. I was already exhausted when I walked to the Eastern Scheldt with my GUE CCR, DSLR, deco stage + video ligths. Underwater there was a lot of current. Although I had a new scrubber my...

    Basic gear from mid-twentieth-century Spain: Nemrod

    I’m still using my old nemrod spg for my dilluent of my (gue) JJ ccr. I like the display of my nemrod spg, it’s easier to read the pressure of the nemrod spg. I don’t know how old my nemrod spg is, I didn’t buy it new. I was already the second owner.

    Cave 2 geeft je inderdaad bij dezelfde grotten/mijnen veel meer mogelijkheden en langere duiken dan cave 1. Zelfs zonder trimix met een ean32 stage + zuurstof stage heb je totaal andere duiken. Zelf maak ik het liefst 1 lange duik. Dat deed ik ook al toen ik nog oc dook in Mexico en Frankrijk...

    Kroatië is altijd leuk, tech 1 vind ik de leukste cursus die ik heb gedaan. Het voelde als vakantie, mooie duiken en weinig stress. :cool: Het zicht was inderdaad wat minder bij Nuttlar. Maar het was gelukkig nog steeds een mooie en leerzame duik. Hetzelfde geldt voor de duik in de...
