As for the training at altitude thing that you mentioned....what a bunch of BULL$H!T. That's like taking a diver to a quarry that's 60 degrees and forcing them to make dives in a 2.5mil shorty. IT's just wrong...if you're at altitude...teach the students to dive at altitude. IF you're in a cold quarry teach them how to dive with the proper exposure protection. I don't understand how this should even be an issue
.

get on with learning to dive. I hope your new shop will provide you with quality training and introduce you to some new friends.

From General Standards and Procedures page 10:
4. For training purposes,an open water dive is a dive during which a
student diver spends the majority of time at a depth of at least 5 metres/
15 feet and:
a.breathes at least 1400 litres or 50 cubic feet of compressed gas.
OR
b.remains submerged for at least 20 minutes.
From General Standards and Procedures page 25, section on frequently asked questions:
Use theoretical depths. This meets the intent of minimizing
decompression risk. At altitude, maximum actual depths con-
vert to theoretical depths that are beyond training dive stan-
dards.
Regarding the minimum depth requirement for skill evalua-
tions,use the actual depth 5 metres//15 feet.
From Open Water Diver Course Instructor Guide page 3-43:
2. You need special training for altitude diving.
[Outline specific course procedures for diving at
altitude if open water dives will take place above
300 metres/1000 feet and promote upcoming
Altitude Diver specialty courses.]
From General Standards and Procedures page 33:
{In order to attend an IDC the candidate must:}
4.Have been a certified diver for at least six months and have completed
and logged at least 60 dives showing experience in night diving,deep
diving and underwater navigation (as documented in the individual s log
book.)
Note:To attend an Instructor Examination (IE),the instructor candidate must have at
least 100 logged dives (exceptions may include PADI 5 Star Career Development
Center candidates.)
We went to that altitude, we actually live at approximately 4500 ft.Stephen Ash once bubbled...
ScubaDon, answer as many of these questions as you can and I might be able to give you some ammo for your letter.
1. Did you ascend to 6000 ft. or do you live at that elevation?
Only actual. The only thing he said about diving at altitude was that there were special conditions about that if you dove above 1000 ft. And you had to have a different class for that.Stephen Ash once bubbled...
2. Did the instructor discuss actual and theoretical depths?
Actual depth on all dives were between 21-24 feet.Stephen Ash once bubbled...
3. How deep did you go? (It should be in your log book) Actual depth, please.

Computers were never even discussed in class, let alone while we were diving.Stephen Ash once bubbled...
4. Were you using a computer? If so, did your instructor show you how to set it for altitude?
[/B]
Yes it was a depth gauge, not sure what type, it was Scuba Pro.Stephen Ash once bubbled...
5. Were you using a depth gauge? Was it a Bourdon tube or capillary gauge?
[/B]
Twice with twice without. He basically told us to use it if we didn't feel comfortable or had trouble equalizing.Stephen Ash once bubbled...
6. Did your instructor use an ascent and descent line?
[/B]
In the pre-dive brief, No. In class, yes.Stephen Ash once bubbled...
7. Did your instructor make mention of the need for a 30 foot per minute ascent rate in the pre-dive brief?
[/B]
No. I had done some reading on my own on one of the local web pages about dives here in Utah and it mentioned about using that table. The chart was never discussed in class or at the OW dives. So in answer to the question no we did not calculate our pressure group using the altitude chart.Stephen Ash once bubbled...
8. When you all logged your dives and calculated your pressure groups did you use a theoretical depth at altitude chart?
[/B]
Dives were done at the Homestead crater and water temp is 95-98 deg. No exposure protection used.Stephen Ash once bubbled...
9. What was the water temp? What type of exposure protection did you use?
[/B]
Yes we did do all of the dives at that altitude, 4 in all. 2 the first day, a drive home 45 min over 8000 ft. pass. Back the next day for 2 more dives and back home the same way.Stephen Ash once bubbled...
10. Did you do all of your OW cert dives at this altitude? How many dives did you do each day?
