At my age, ND, if I find myself at a depth any where near 100 metres, the last thing I'd be worried about would be what time it is!

Hope this works,for those with FB maybe.

20 minutes? I mean you must know how long your down Saitch. Death by running out of air, Death by over staying or coming up to quickly, Death by not following or stopping for recompression stops.. ALL at time and essential mate


The Civilian rulz

Maximum Dive Time (MDT)This is the time you can spend at a given depth without having to do a required decompression stop during ascent. This time is also known as the Maximum Allowable Dive Time or no-decompression ddmit.Decompression StopThis is a point in a dive where you stop at a specified depth for a specified time during ascent to allow nitrogen offgassing before continuing your ascent or surfacing.Precautionary Decompression StopThis is a stop at five meters (15 feet) for three minutes as a safety precaution when you have not exceeded the Maximum Dive Time. You should perform such a stop at the end of every dive. It is also known as a Safety Stop.Required Decompression StopThis is the amount of time specified by the NAUI Dive Tables, that you must spend at five meters (15 feet) whenever you exceed the Maximum Dive Time. Other tables specify additional stop depths for deeper or longer dives.Actual Dive Time (ADT)This is the elapsed time from the moment you begin your descent from the surface until the time you return to the surface. Time spent at your Safety Stop does not need to be included in the Actual Dive Time when determining your Letter Group.Residual NitrogenThis is the excess nitrogen remaining in your body from any dive or dives made before you have completely offgassed.Letter Group DesignationThis letter symbol identifies the amount of residual nitrogen you have in your system. The closer the letter is to the beginning of the alphabet, the less residual nitrogen you have in your body.Surface Interval Time (SIT)This is the time spent on the surface between dives. During this time, your body is eddminating excess nitrogen. Your Letter Group will change and move closer to the beginning of the alphabet, depending on how long you are on the surface.Repetitive DiveThis is any dive that you make before you have completely offgassed from any previous dive or dives.Residual Nitrogen Time (RNT)This is the amount of time you must consider as already having been spent at a given depth for a planned repetitive dive. This time is based on the residual nitrogen remaining in your body from a previous dive or dives.Adjusted Maximum Dive Time (AMDT)This is the Maximum Dive Time minus the Residual Nitrogen Time for a repetitive dive to a given depth.Total Nitrogen Time (TNT)This is the sum of your Residual Nitrogen Time and your Actual Dive Time following a repetitive dive. You use this total to obtain your new Letter Group at the end of the dive.


If we add fresh water and diving at altitude it gets very confusing so I will leave that alone

Info copy and paste as usual for me
The Tesla battery is rated to IP66 or better, which means it is protected against strong jets of water1. The battery's electrical components, particularly those in the high voltage sections of the motor, speed controller, and battery, are rated to IP66 or better1. One or more modules are combined within an IP67-rated steel enclosure2.

The post water fires show what Blind Freddy should know that the Tesla IP66 rating which is NOT water proof for swimming should take the advice if the car is sunk

PS My very light running watch is rated to 100M underwater. NO WAY I take it diving. My very old Seko automatic Diving watch is the only one for that The fires in EV or faults in ICE post a deep swim are expected I think for most types.
Ps I brought a TOUGH diving watch when doing my 2nd Diving course with the Navy, First was PADI ( fun but PITA now)

I broke the tough one rated to 50m every day for 4 days in less than 10 metres of water, A sad day on the 4th day when I accepted a 100 m watch IF I DID NOT bring it back broken the next day, IT Broke at 10 M or less!

Not grumpy as it is funny!
EDIT I check my Diving log for the 10metre water edit

Those "depth" ratings are actually pressure ratings, as in atmospheres (ATM) - which, if you go for a swim in a pool you can quickly overwhelm because when you punch your arm into the water doing, for example, freestyle, then the actual pressure on the watch can be a lot more than, say, the 10 ATM ("100m") rating the watch has.

I have an old Omega quartz watch that's supposed to be 100m water resistant and it has had its mechanism replaced twice after me just going for a swim after a battery change, where the jewellers who did the battery change guaranteed it would be waterproof.

But if I do a free-dive holding my breath I don't need to decompress?

You and I cannot live if we freedive deep and stay long enough to require compression

Trivia Deepest - Herbert Nitsch, often known better by his nickname as the "Deepest Man On Earth," 214 meters (702 feet). The female deepest dive world record holder goes to Tanya Streeter, who dove to a depth of 160 meters (524 feet) off the coast of Providenciales.

My depth record is happily a LOT closer to the surface.

Not specifically EV related but Tesla got top spot in this one (which isn't a good thing) but all new cars suck as far as privacy goes (no surprise really) - Just a moment...


From the article -

Some not-so-fun facts about these rankings:

• Tesla is only the second product we have ever reviewed to receive all of our privacy “dings.” (The first was an AI chatbot we reviewed earlier this year.) What set them apart was earning the “untrustworthy AI” ding. The brand’s AI-powered autopilot was reportedly involved in 17 deaths and 736 crashes and is currently the subject of multiple government investigations.

Councils who do and those that HMMMM?

Stopped in Camperdown 4 times in the last few days. A 50kwh charger there is more than helpful. Coffee, Breakfast for a early Chemo Express appointment for a Diabetic in Geelong, Supermarket supplies...I spent over $100! the power cost about $5 or so each time as well.

Driving through Colac with a BIG smile on my face. The 4 electric Jesus fast chargers in Colac I cannot use are beside two SLOW electric Jesus chargers one of which one of which never works and the alleged 7kwph charge was closer to 5kwh.
Colac took me 3 hours to get enough power to get to any Decent charge points in my short range

Not sure why but no electric Jesus chargers are working for me now. One public one in Warrnambool refused to play as did one in Port Fairy. Not fussed really as the slow ones are really a PITA and could spoil a weekend

It is interesting that electric Jesus chargers only charging Telsa on public land at councils' expense perhaps?
