Upright divers are always good. As are: upright democrats (and republicans, of course), upright citizens, upright tax payers. But I digress ... so back to diving and I'm now citing from the (German) SSI training booklet for dry suit diving (German edition, ISBN-13: 978-1-59750-077-7):
«Damit das automatische Auslassventil richtig funktioniert, muss das Ventil richtig eingestellt sein und der Taucher sich in einer aufrechten Position befinden.»
[«For the automatic exhaust valve to function properly, the valve has to be adjusted correctly and the divers needs to be in an upright position.», my humble translation, my emphasis]
