Nitrox?

[dmaziuk]

I did buy an even cheaper Cressi Leonardo for me and my wife. Less than 100 eur new on Amazon Prime Day.
Quite conservative compared to more advanced ones, which for me is good.

I doubt Mares is much different in terms of conservatism, but it does have a USB uplink instead of Leo's IR. Which these days is a plus if you want to keep your dive logs without resorting to calligraphy on dead trees.

Hmmm... what did divers do before dive computers?

I actually see quite a few divers on cruise W/O them.

They used these:

People learned them forwards and backwards, it was part of standard OW training.
All you needed was a depth gauge and a timing device and the tables memorized and you went diving.
What gear configuration do you have, or do you rent?

Tables.

Info - Why are tables not taught in OW classes anymore?

Many new divers have been trained only to use dive computers; they have had no introduction to or any familiarity with dive tables. Many posts on ScubaBoard respond to posts about “what do I do if my computer fails” with the statement, “just use tables.” This is a disconnect…. Here is the...

More than 30 years ago since I or anyone else I know used tables.

This theory has been thoroughly debunked.

I cannot say I agree with this myself, I certainly feel less tired after diving on Nitrox, especially over 24 metres. Most people I dive with also think this. Personally I cannot see how anyone can disprove this claim, it is highly objective.

Mmm well .....

But this article says it could be due to reducing the sub clinical DCS symptoms

You go diving and she is gone massage/shopping/sun worshipping etc with your plastic!!
Majority of tourists visiting eg. Bali and Phuket are not interested in scuba diving.

Actually she does snorkel. We often look for dive ops that allow bubble watchers. On a December '22 cruise to the ABCs they let her come along and snorkel while I shore dived in Bonaire and Curacao.

When we were just in Roatan she was on the dive boat and snorkeled while I dived. She said it was the best snorkeling she ever done in her 40+ years of snorkeling.
I first took her snorkeling on our honeymoon cruise in 1979.

You’re lucky she at least snorkles. My bride has done it on occasion if it’s a family trip or something - she did Molokini when we took our daughters to Hawaii - but as a general rule she’s just not interested.

Now, if it was a dive excursion where she could drink champagne and lay out while I’m down, she’d be all over that.

 

[Posinator]

The short answer is yes.

Besides the NDL I'm not as tired when diving nitrox. For example in Roatan I was doing 5 dives a day. Never hit NDL and I wasn't as tired.

Nitrox and rescue are two classes I recommend EVERY diver take.

Other than that, what @tbone1004 said.

Same with me. There is no doubt I’m less tired after repetitive dives on Nitrox vs air

I've kept track of my depths and times on all my dives. Not having a dive computer I always ask the Dm/guide at the end of the dives and write it down in my log.

These are always canned 2 tank dives so one assumes the DM knows the depths and times since they do them every day for cruise ship passengers. They also know the pressure groups and surface times and certifications of the divers.

In my experience of 26 dives they do a pretty good job of looking after you and profile the dives to the least experienced diver. 60 feet and 45 mins are the outside limits for dives. Unless there are a lot of divers in which case they will split the group based on experience and certifications. They are quite used to having inexperienced divers. In other words they pretty much hold your hand throughout the dives.

As for equipment, I have a wetsuit and a mask, I rent everything else. I'm not cruising/diving again until next January. I hope to have a dive computer by then as well.
