tanks depend on the country what is available and water temp.
here in aus the standard is becoming 2 luxfer 80's and 1 luxfer 40 for 02. the 80's are a bottom stage and deco %50 the 40 for 02.
We used to use 40's here for %50 but it becomes more practical to use 80's as u can do 2 tech1 dives with the one fill and luxfer 40's were hard to get here until recently.
i know the brits almost always use 80's for %50 as they dive colder water and big current wich can increase your sac a lot.
in your warmer water and with what is available it is up to u if u want 2 lux 80's or 1*80 and 2* 40's ask some local tech2 guys or Gideon (GUE instructor in singapore) as he dives the same temp water as u. I think the 80's are much more practical for multi day diving and a weekend away where it is hard to get fills.
good luck |
