Are dive computers making bad divers?

I know this is just the basic scuba forum but geeeesh, have some respect! Don't tell me you're just jumping in the water without 3 gases, 3 dive plans, 2 computers, tables, wet notes, and oh before I forget, TTS prominently displayed on your DC! What are you thinking?

Damn. Always miss the forum title!

Now now kiddies, always do what your divemaster tells you

You can also finally do that 3-5 minutes safety stop even in Perdix tec mode since a recent update rather than looking at the GF or remembering at which minute you started the safety stop

I've got tables in my pocket and an analog gauge, hasn't failed me in more than 25 years.

Your question is akin to asking if the iphone and mapping software makes bad drivers - people can become technology dependent and complacent which is a dangerous mindset and results in incidents where simple problem solving skills would have saved folks.

Men went to the moon on slide rules. They came back too.

For the Apollo space missions NASA designed a special pen which would allow writing with ink in low/no gravity conditions. I believe it cost thousands of dollars to develop and produce. When the Russians were asked how they solved the problem of writing in low/no gravity environments, they said "Oh, we use a pencil and a pencil sharpener"!

I thought you always could do a timed safety stop in OC tec mode, but you had to start a timer manually which counted up like a stop watch.

Fun story, but not true.

FACT CHECK: NASA's 'Astronaut Pen'

Space race legend claims NASA spent millions of dollars developing an 'astronaut pen' that would work in outer space, while the Soviets solved the same problem by simply using pencils.

Both U.S. astronauts and Soviet cosmonauts initially used pencils on space flights, but those writing instruments were not ideal: pencil tips can flake and break off, and having such objects floating around space capsules in near-zero gravity posed a potential harm to astronauts and equipment.
[...]
The “space pen” that has since become famous through its use by astronauts was developed independently by Paul C. Fisher of the Fisher Pen Co., who spent his own money on the project and, once he perfected his AG-7 “Anti-Gravity” Space Pen, offered it to NASA. After that agency tested and approved the pen’s suitability for use in space flights, they purchased a number of the instruments from Fisher for a modest price.

So the real gist of the story is not "NASA spent a ton of money developing a special tool when they already had something perfectly good at hand," but rather "NASA made do with an imperfect tool until someone invented a better one, which they then switched to." One might even say the same about divers.

That's funny, I bought 2 space pens from divelogs.com many years ago, probably around 2004. They both work perfectly today, and I have a couple of refills. May outlast me.

You are right, I didn’t know you could add a timer in the configurable row, it was added in 2015 to the Petrel and is available on the Perdix

Timer???

For the Petrel: I see that a timer has been added as a possible display item for center row in the new updates. How is it accessed/used (on/off/reset)? No mention in any literature i can find. Thanks.
