There are two main strategies with a drysuit:
- either dive with the valve fully open, then you just use the size of the undersuit to provide enough bulk to keep warm
- either close partially or more fully the valve and keep it well inflated to keep warmer
I won’t argue about the pros and...
Another vote for Swanage and Portland.
Unfortunately like @Wibble said, Swanage Boat Charters and Divers Down will close at the end of the month for winter.
You could drive to Porthkerris Divers next summer, you can stay there and either dive from the shore or book a place on their boat, if...
I have done a pool dive with an AP CCR but it was only a 1m deep pool at a dive show so you couldn’t get a feeling of how CCR works with buoyancy and the unit was already assembled.
I’ll look into this, thanks. Would be useful to do the prep so I know what I am getting into before to pay...
A few years ago, during a class, we went slightly past the NDL because one of the students made a mess while trying to lay a line (that was a recreational SSI Wreck class)
Even though I had read the manual of my computer, I felt anxious because, at the time, I had never went past the NDL. It...
Holy necromancy 😂
The previous reply was from 2004.
I used to have a Suunto transmitter and hated it, it would disconnect and be fussy to connect. I have an AI transmitter for a Shearwater that I use only for statistics and it never failed so far in about 100 dives I used it.
Out of curiosity what would be your prep time if you dived tomorrow:
What do you do the day before and how long does it take?
What has to be done on the day of the dive and how much prep time you need?
What do you need to do on the boat before the dive?
I am quite meticulous and wouldn’t skip...
Using the same logic, the thresholds should be:
- 5 /1.01 = 4.95
- 5 / 1.05 = 4.76
- 5 / 1.1 = 4.54
Because if you measure 4.54 + or - 10% then you are anywhere between 4.54 * 0.9 and 4.54 *1.1.
So for the purpose of testing for CO you’d take the most conservative value which is to assume...
About the state of mines, I have never been in caves or mines but I have an interest in doing it in the future, so trying to read about it.
While following Facebook groups about other mines, I have sometimes noticed posts complaining about the state of the wood/timber underground but I have...
Well I am pretty sure English is not the national language of Mexico.
But does it matter? That’s how it is used and the meaning of words evolve over time …
Even Wikipedia has an article to clarify it:
I have no bone in this, I am French :)
