When you get your DM kit it comes with the eRDPml and no tables. understanding of the relationship between depth and time for NDLs) Supreme executive power derives from a mandate from the masses, not.
The math they use for diving even the EANx material is elementary school material. I think because of the inherent risk associated with diving you should be able to think on your feet and the simple math required is nothing. I was totally amazed how many people memorize the numbers Make the calculators waterPROOF down to rec diving depths, at leastmake them strong enough to drop a tank on them without breaking them, and make them solar powered so you never run out of batteries, and then they'll approach the versatility and durability of simple plastic tables.
Yep, I always have my tables and a self-winding dive watch. I'll leave the tables on the boat and mark the time I hit the water. I do this even though I have a computer. I still calculate my pressure groups often I'm off the tables due to multi-level diving. I am actually thinking about getting the wheel and learning how to use it.
The book that comes with the eRDPml explains how it works which is good. I recognize there is an argument to made for the fact that pretty much everyone dives with computers these days. Heck, so do I. But until these courses referring to ones that omit training on tables, which I still believe give divers the best conceptual understanding of the relationship between depth and time for NDLs start giving detailed instructions on how to FULLY use a variety of computers out there on the market today, I think they're doing their students a huge disservice.
Just had a thought. There really is no reason for me to need even the eRDPml. I'm not sure but nothing in the kit indicates I'll need to teach RDP. I doubt this would be considered disparaging. I am still old school: Tables are still my best friend. Hell, I still take 'em out for dinner when I'm diving on occasion. Yes, but they are pretty near impossible to break, they don't need bateries and they are waterproof so you cna take 'em with you just in case you blow your plan.
I am indeed completely perplaxed by SDI's decision to make every dive a "Trust me" dive by teaching a computer only-I do truct my computer, but if needed, I can easily adjust to tables on any dive because I still bring then and I still use them in my dive planning as a back up and always have a back up timer.
Or was that NAUI? I just picked up my DM kit two weeks ago. Once that runs out I'll make my own. Just started my DM training. I heard they have different exams based on whether you were taught with eRDPml or the wheel. The math they use for diving even the EANx material is elementary school material.

Just had a thought. There really is no reason for me to need even the eRDPml. I'm not sure but nothing in the kit indicates I'll need to teach RDP. I doubt this would be considered disparaging. But the legal documents I have to sign clearly leave room for getting in trouble for something like that.
I'll throw in a checkout dive tank fills and rental are extra. Next time I go to the Caribbean I should stop to see who was certified by which agency. Did you take the classroom portion online or in person? I dont see electronic regulators at any point of the diving future but i do see automatic gas blending rebreathers. Though they are very cost prohibitive for the recreational diver.
I got tables with OW and Nitrox. Personally, I think teaching tables is a good way to teach basic deco theory. There is a lot to be gained by playing with the information on tables.

That, and if you ever find yourself with a dead computer, you can wing it better if you have a grounding in tables.
Lastly, as much as I hate to admit it, PADI is the agency of general choice simply because of thier size. Everyone knows PADI in rec diving. Good thing I just have a lapsed DM card I don't worry about it.
Classroom was done in person at the dive shop. I've said it before and I will be happy to repeat it. The more you can work tables, the better your understanding of NDL's-hadn't thought about deco procedures, but that definitely makes sense.
Personally, I enjoy doing a few table problems-helps with dive planning and dive time management. Or are the standards different at the "advanced" level from agency to agency? Has about 50 hours use on it. Yellow case with black everything else. Large harness, large lungs. This is an excellent unit if you are looking for a rebreather. If you are not familiar with these, think of it as a personal nitrox mixing machine which constantly adjusts your mix for the perfect mix at whatever depth your at.
While removing the co2 and adding new o2, you can get up to 4 hours on one dive. Because you are using hte same gas, the depth affects it minimally.

You can deco on the machine too, with it adjusting your mix to richer o2 as you go up. Even rec level diving can be done much more efficient with high 02 mixes for your safety stops to reduce chances of DCS. I would be happy to recommend local sources for training. ADV with manual shut off added. Adapter for 4th cell sold separate if you want one.
Many spare parts, hose, tools, and accessories. I might throw in a keg of sofnolime if I still have any left at time of sale. This is a great machine. I will discount items below if added to rebreather sale.
Serious inquiries only please. Used once on test run. West Seattle it's NOT ok to contact this poster with services or other commercial interestshttp: In conclusion I dont see any agency being better than the other. Depends on what you mean by the "advanced" level.
Means different things to different people The question is, how much does the agency matter, at what point, and why? For recreational diving at least, OW through Rescuethe instructor matters more than the agency.
Beyond Rescue, at the Master Diver level and beyond, the agency starts becoming more relevant. No, there's nothing wrong with PADI. We like to slam them becuase they are the biggest dog on the block. I would recommend that you talk to other divers before making your choice.

- Dive Tables
A lot of instructors can seem like great, personable folks, but suck at teaching diving. If you've never been through scuba courses before, you probably won't know if you are getting good training or not. Don't get caught up in the C-card frenzy. Padi has a "class" for almost any type of diving you could ever imagine. Most of this is stuff you can learn on your own if you just go out and go diving. You probably will learn a lot more. Do what I did. My shop owner bought the shop so she could get discounts on dive equipment.
She is a diver first and a store owner second. Get enough training to keep the shop running and she is happy to help you with other things for free. She arranges dive trips but makes no money on them. Again, she gets a discount free boat ride and EANx tank fills for her for bringing a bunch of other divers and she is happy with that. The packages can be ordered pretty much however your shop likes to order things You can order the packets from PADI with the rdp, erdpml, or without a table at all - PADI is now giving instructors the ability to teach solely based on a dive computer, and the exams will soon reflect that option different exams - one for tables, one for computer So, it is an in house decision amongst the shop and instructors as to how you want to teach the course.
It is my opinion that everyone should learn the tables so they understand what their computer is doing, should they get one A word of wisdom I was given years ago that has served me well is never let a dive be a "Trust Me! That is have the basic knowledge of that particular dive, whether it is skills, knowledge or plan so you can safely end the dive without relying on others.
For example, I am impressed with a number of divers here in their skills and abilities with regards to cave diving. But I would not even think about doing a cave dive even with them leading until I have the skills and knowledge to do so safely. Not that they would even allow me on that dive without it-because their safety would be jeopardized as well. The same goes for a computer.PADI RDP Table questions Divemaster and Instructor exams
If I don't understand the theory behind it, every dive I dive with it is a "Trust Me! Even today, I still work tables as well as my computer. You know, even in training, everything that can be done is done to prevent trust me dives. In OW, academic reviews before the pool. Shallow end before deep end. Pool before OW and the like.
The goal is should said instructor die underwater, the class doesn't have to die with him. This has held for every level of diving I have done. I am with you - I avoid trust me dives whenever possible.
