One dead, one missing - Palermo, Italy Another case where deep diving on air might have been the main contributing factor to 2 deaths.

They started the investigation. According to this source the tanks were filled with air, no trimix. Sub annegati a Isola delle Femmine: le bombole erano caricate con aria According to this other source, which is quoting a local diver who knows the wreck, the wreck starts at 78 but to explore it...

No spearfishing the source mentioning it retracted and apologised.

The name of the wreck is Loreto. Also in one of the video the interviewed person mention four cylinders each diver, son looks like tech config.

Ok name of deceased have been released: Palermo, un sub morto e un disperso durante immersione. Esploravano un relitto a Isola delle Femmine Also the dynamic of the accident is now a bit clearer: 2 Scubadivers went to explore a wreck in 70 mt of depth. 1 remains entangled The other one goes...

Just for situation awareness sub (the term used in the articles) is short for subacqueo somebody who goes underwater no matter how. Also in an another article it is mentioned that no tools for fishing were found and the depth in the area is 80 mt with a wreck. A Isola delle Femmine muore un sub...

The bar is a seat for long distance scootering in order to relieve pressure from between your legs ... and move it on your butt. Water at 60 is about 16, used to be 14 but the Med is warming up, unfortunately for the ecosystem.

Not related but interesting since it is also a decompression: astronauts before a space walk pre-breathe oxygen for a few hours. This is because they want to keep suit pressurization to a minimum to reduce stiffness and therefore fatigue. This means they would be subjected to DCS. So they...

I dive mediterranean sea on deck even 40 degrees (C which is 104F) usually 35 this season and water up to 26 surface but dropping to 14 or 12 at depth. So I dive dry. It is doable. Just need to manage the heat: Wear it possibly in the shade Wet it asap keep it wet Once on dive spot jump in the...

That would be interesting to discuss.... Entanglement? Lost in a cave system? Rescuing somebody? Do you have a near miss thread about this? Thanks

I have got a 300 bar Coltri compressor and I bank air in my old 250 bar 12+12 steel double. Keeping the manifold closed I have a small cascade. I run the compressor (with double filter and condenser) only once every 3-5 weeks. Except if my sons decide to dive .... then I have to fill their...

Been there doing that :D

I cannot speak for @Dr Simon Mitchell, but from a few exchanges I had with him (I am quite interested in O2 retention) I understood that being CO2 tolerant only moves further up the concentration at which you have a response to it. So the only thing that happens is you can walk closer to the...

It is. There is noticeably much more effort in moving the gas in CCR, since OC all you need to do is keep the demand valve open by maintaining depression in your mouth. In the reb you need to overcome the viscosity and inertia of the gas in the entire loop and, according to the configuration and...

I have been certified for OC trimix for quite a while (hipoxic) but then when the cost of filling started adding up a friend convinced me to move to CCR. Now the nice thing about CCR is you can bring down multiple gas and you can plug them into the loop and make many gas switches. I did a...

The only time I have got a CO2 hit I was in OC twinset and 3 stages .... I was at 12 meters and my instructor showed me what it means to retain CO2. To recover I spent 30 minutes on the surface. It is bad and at depth you cannot carry enough gas to overcome it .... I disagree fully about not...

By the time we separated we already had scootered 10 minutes .... so the shotline was long gone ....

Hello, first here in Italy variation is very small almost negligible (from a few prime to a whole degree east). To convert from true north to magnetic north use the east is least west is best (subtract east variation from true and add west). To calculate how much you would be off you can use the...

Thanks, no worries the next day I was diving and scootering happily again. An easier dive 45 min at 40mt with about 30’ of deco. 75 total run time .... :D we did not separate this time! I am going to implement a few suggestions and the do a solo navigating exercise in a known place and then...

True ... but there was no plan B. That is the near miss. No plan will survive reality, but planning is everything. Allows you to evaluate options and reduce unforeseen circumstances and make others’ action expected and non unexpected.
