k lets say ima do a dive to 100 feet with doubles ima stay for about 40 mins when its time to go up ima stop at 80 for a min then 60 for a min then 45 for 50 secs then 25 for 50 secs then ima sit at 15 for couple mins then surface depending on air? type of thing?
Actually, every dive planning program I have tried would give stops quite a bit different from that. The US Navy and Canadian tables are nothing like that either.

You want to take a course like TDI offers...
Decompression Procedures
This course examines the theory, methods and procedures of planned stage decompression diving. The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maxium depth of 150fsw/45msw unless taught in conjuction with advanced nitrox, Extended Range or Advanced Wreck Courses. The most common equipment requirments, gear set-ups, decompression techniques and decompression mixtures (including oxygen and nitrox) are presented.

Saying explicitly what others have hinted at....DO NOT ATTEMPT DECO DIVING IN ANY FORM UNTIL YOU HAVE THE TRAINING FOR IT

Diving deep for no other reason than diving deep is probably not a good idea. Deco diving (other than the every dive is a deco dive) without training and equipment is asking for a chamber ride at the very least.

V-planner is neat, but it does you no good if you're at your first stop and realize you don't have enough gas to complete your profile.

The questions you're asking make me think you're considering doing this soon....do yourself a favor. Don't.
 
scubasix ima not be doing it soon im 2 poor for doubles im thinking maybe end of the summer or next year we still have 20 feet of snow on the ground we are still riding snowmobiles lol im just asking what pop into my head when i was reading a table so i dont forget these things
 
String:
Decompression isnt something to be scared of. Despite some agencies trying to scare people off contrary to what they want people to think it isnt that difficult, isnt that dangerous and you dont die on entering decompression. At its basic level anyone capable of buoyancy control is capable of a decompression dive with the right equipment.

Need to add emphasis on "right equipment". Entering deco means you no longer have the option of going to the surface to sort out problems, at least without a possible trip to the chamber. Entering deco on a std rec rig could turn out badly.

Thats smart. The kind of questions you were asking were sounding like you were planning on doing it without training.

Doubles ARE expensive. Who would have thought something as simple as bands could cost as much as they do. My manifold has been sitting unused since i got it while i'm slowly acquiring the rest of the stuff i need..... ugh!
 
ya they are pricy i landed a job at yamaha as a mech so im getting payed not bad :) oh ya ima not start deco till i do the tech diving course cause im only turning 17 im just planning and learning more about deco diving. less you know of a padi course that does deco at younger or offeres a course that helps and teach you about deco?

I'm not sure, but I think you're going to have a problem finding a PADI (naui or SSI) course that teaches ANYONE deco. Their primarily rec diving.

The TDI Deco Procedures course requires you be 18 or older.

Based on your Profile...you are OW...
so you have several classes ahead of you....

Before you get into Tech...
You might want to get your recreational Deep Diver

The following 4 would be course you'd take if you go the TDI route
Nitrox
This is the entry level certification course for recreational divers wishing to utilize enriched air nitrox (EAN) as a breathing gas. The objective of this course is to train divers in the benefits, hazards and proper procedures for using nitrox mixes from 22% to 40% oxygen content.

Advanced Nitrox
This course examines the use of EAN 21 through 100% (oxygen) for optimal mixes to a depth of 130fsw/40msw. The object of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN 21 through 100% (oxygen) for dives not requiring staged decompression. (Decompression techniques may be combined with this course at the discretion of the instructor).

Decompression Procedures
This course examines the theory, methods and procedures of planned stage decompression diving. The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maxium depth of 150fsw/45msw unless taught in conjuction with advanced nitrox, Extended Range or Advanced Wreck Courses. The most common equipment requirments, gear set-ups, decompression techniques and decompression mixtures (including oxygen and nitrox) are presented.

Extended Range
This course provides the training and experience required to competently utilize air for dives up to 180 fsw/55msw that require staged decompression, utilizing nitrox mixtures and oxygen during decompression.

hope you've got lots of bucks :-)

At least around here, they'll allow you, at the instuctor's discretion, to combine Deco procedures with Adv nitrox. With the exception of a very few specialized and shallow dives, I'm not sure what you'd use Nitrox above 40% for if you weren't decompressing with it.
