PADI tables finally going away?

[ScubaSteve]

Hope it's not the Temp.

MEOW!!!

60 degrees is beautiful and I dive wet. Of course I used to think 45 was comfortable and now I am finally investing in a dry suit so I suppose I am going to be by your side sooner rather than later

Remember someone said you can get a PDC for about $200?

This is what I had found and it gets pretty good reviews:

Aeris XR-1 Computer Console

I prefer two buttons to one... but the price is great.

To be able to function as an independent diver with the ability to participate in a team sport. To suggest to them that they scour the boat and other divers to find another computer instead of teaching them the tables which would allow them to maintain their sense of independence does a disservice to the student. By the way, having a set of tables IS a very good way to deal with an unplanned contingency.

Assume that the PDC failure occurred after the first multi-level dive, what are the recommended schemes for continuing to dive within the next 12 hours?

I suppose you could use the tables based on maximum depth and total bottom time but that would result in a pressure group that could be well beyond what resulted from the multi-level profile of the previous dive. It could be well beyond the edge of the tables if the dive started quite deep and averaged quite shallow.

Since the debate revolves around teaching the tables at an elementary level, I will suggest that trying to do multi-level profiles with tables is out of the question. I sure don't know how to do them!

But I don't see how a borrowed computer could be used. That computer would have no information about the previous profile and there is, to my knowledge, no way to insert it. It seems to me that the diver is on the bench until their accepted nitrogen clearing time passes. But today is shot!

The NiTek Duo is designed for use by one diver at a time. Divers should not share a single NiTek Duo—or any other dive computer—on the same dive. Additionally, no diver should lend their NiTek Duo to anyone else until it calculates that no measurable residual nitrogen remains after previous dives and no longer displays the “desaturation time” indicator while in time mode. Further, no diver should use their NiTek Duo for repetitive dives—unless that same properly functioning NiTek Duo has accompanied them on all previous dives in the same repetitive dive series and is thus, accurately monitoring the diver’s total exposure to oxygen and nitrogen.

Do not rely solely on this or any other dive computer. Take a back-up dive computer or dive tables (along with a separate means of monitoring depth and dive time).

If there are other techniques that could be employed, I would like to learn about them.

Maybe a PADI instructor can post their Standards for student equipment. I am not a PADI instructor, and so I have no idea.

Equipment Requirements
1. During all open water training dives, each student diver, certified assistant
and instructor must have:
a. fins, mask and snorkel (Although recommended, Ice Diver, Wreck Diver
and Cavern Diver Specialty course students are not required to have
snorkels.)
b. compressed gas cylinder and valve
c. buoyancy control device (BCD) (with tank mount or separate backpack)
and low pressure inflator
d. regulator and alternate air source
e. submersible pressure gauge (monitoring device)
f. depth gauge (monitoring device)
g. weight system and weights (if necessary for neutral buoyancy)
h. adequate exposure protection appropriate for local diving conditions
i. at least one audible emergency surface signaling device (whistle, air
horn, etc.)
2. During all open water training dives, instructors and certified assistants
must also have a timing device, compass, knife/diver’s tool (except where
prohibited by law or local regulations) and two surface signaling devices –
one audible (whistle, air horn, etc.) and one visible (inflatable surface tube,
flare, signal mirror, etc.).
3. Use a dive flag where required by local law. Consider using a surface
support station with a dive flag.
4. When student divers will use dry suits for the first time during open water
training dives, they must complete a confined water dry suit orientation
session prior to participating in the dives.
You may use the dry suit confined water session in the “Adventures
in Diving Program Instructor Guide” to conduct this orientation. It’s a good
idea to have student divers use dry suits during confined water dives to gain
familiarity and increase comfort.

How odd that students aren't required to have some kind of timer.

Agreed,but my guess would be that studentdivers (OW) have trouble enough reading their SPG,so PADI thought them to be some kind of overkill.
But this will change aswell,depthgauge became must have's not so long ago.

...... Remember someone said you can get a PDC for about $200? Well, looky here:

Depth Gauge for $90.00
Dive Watch for $89.95
or
PDC for $200 .........

PDC are becoming:
a) widely used
b) cheaper
c) easier to learn ... see videos:
VEO 100 Introduction
VEO 100 Settings
Making a Normal dive with the VEO 100
.... more on the way .... stay tuned

the earlier in the diving career a student can turn their brain off the better!
kudos!
