Cave Edition

Post by Tastenchef »

Moin

ich hatte mal irgendwo gelesen das es eine Berechnung für Bailout geben soll um den gleichen weg rauszutauchen wir rein.

Für die Deko gibt es ja bereits die Variante Gas bis zur Oberfäche wird es das auch demnächst geben für denn weg denn man praktisch ab Punkt X zurück gelegt hat und wieder komplett raustauchen muss ?

Hi,

ja, das genau macht der Cave-Mode. Wir haben diese Firmware-Variante noch nicht öffentlich freigegeben und sie ist derzeit auch nicht direkt zugänglich, aber bei ernsthaftem Interesse können wir eine entsprechende OSTC-Firmware zumailen. Dazu bitte an info@heinrichsweikamp.com schreiben. Die Cave-Mode Funktion funktioniert so wie sie programmiert ist technisch korrekt, ob sie so wie sie ist allerdings auch praktisch sinnvoll und nutzbar ist ist derzeit noch in Erprobung.

Here's some more info about it (available in English only):

What is Cave Mode?

Cave mode is a variant of the gas needs calculation function. The normal gas needs calculation function computes how much gas will be needed to
end the dive in a controlled manner, that is staying within the ascent speed limit of 10 meters/minute (or whatever is set by the diver in the OSTC config) and doing all required deco stops WITH DOING A VERTICAL ASCENT. Therefore it is also named "open water ascent mode". In Cave Mode, instead of a vertical ascent, the gas needs are calculated while following the depth profile of the cave back from the current position to where the dive began. This is called "backtracking". While backtracking the dive profile, tissue off- & on-gassing continues to be computed for the way back and deco stops are added whenever track sections are shallower than the current deco ceiling allows.

How does Cave Mode correlate with OC and CCR / pSCR diving?

When the OSTC is set to OC mode, the backtracking will also be computed using the configured OC gases. With CCR or pSCR mode engaged, the backtracking will be computed in bailout mode, that is again using the configured OC gases. Actually, it is the same logic as with the open water gas needs calculation in OC or CCR/pSCR mode.

What is the role of fTTS/Delay?

This setting simulates staying at the current depth for the set amount of time (in minutes) before the ascent is begun (open water mode) or respectively staying stationary at the current position in the cave before turning the dive and thus begin to swim heading out. In essence, it is a time buffer to figure in some extra time that is needed to call the dive, solve some problem etc. that makes the tissues take up some extra pressure.
