First gear

[scubadada]

The PZ+ decompression algorithm is reasonably conservative, probably something like 80-85/80-85. Nobody publishes the the characteristics of their proprietary Buhlmann decompression algorithms (a side effect of the open nature of the original algorithm). The conservative setting for the PPS PZ+ is simply switching to the next highest altitude setting. You can choose or delete deep stops on any of the Oceanic computers. A little knowledge (emphasis on little) is a dangerous thing. I'm all for understanding the decompression algorithm on a computer before making this important decision.

I would say that, for new divers looking at their first computer, any discussion regarding deep stops (which tends to suggest tech diving) is irrelevant.

They are unlikely to be doing any in the near future and, given the pace of innovation & new thinking, the computer they buy now will, quite possibly, be out dated by the time they are thinking about technical diving

I didn't start looking at gear really seriously until I did about 40 dives in a span of a year (vacation, not local). In that time, I got to talk to a lot of people about their gear, take a look at it, poke around the LDS, chat with awesome members here, and do a lot of research. A lot of the things I thought I wanted at first I didn't end up getting, partially because speaking with people changed my mind and also trying things on in a pool and the fit, feel, etc. Dive gear is not something that I would usually buy online unless there's a compelling price -- in which case my local dive shop is willing to match. Plus, if and when I have issues, it's a short drive away and I like supporting my LDS.

I will also say that a good LDS will work with you to create a "package" that works for you and not a pre-made one. The BC that fits for you, the reg that is within your budget and breathes like you want it to, etc. Give them a chance and ask. I'm also in the camp that other Scubaboard members have mentioned to me before: buy your second gear first. Think about where you want to be eventually and keep that in mind. If you want to do tech diving eventually, think about whether your first stage can be easily converted to DIN and whether the environment you will be diving in is suitable for the reg you choose, etc. Ditto the BC.

New diver taking the PADI open water certification in 2 weeks. So far I have bought mask, fins, boots, and snorkel (Cetatek brand) from the local shop when I signed up for class. . . . I am looking at buying the full kit and signing up for the Advanced Open Water course after becoming certified. Thoughts? Am I crazy and should just get the computer and hold tight?

I appreciate your enthusiasm. And, having your own personal kit really does facilitate more diving, and more enjoyable diving. I won't call you crazy.

Having said that, I - like several others - would suggest that you 'hold tight' for the moment, at least until you finish your OW certification. That includes the computer purchase.

There is A LOT of information here on SB, about BCDs, about regs, about computers. Take some time to search for, and review, threads. (And, I know, that is really difficult when you are very excited and are ready to push the 'buy' button.) Your patience will pay off in the long run.

You mention that you do not have a car, so that may limit your ability to visit area shops. That doesn't mean you cannot call them, or communicate with them online, through email, etc.. You have already received a reply in this thread from DRIS. That would be a good place to start - they are a good shop, with reasonable pricing, and a considerable body of experience. There isn't anything wrong with online shopping, per se, but just because something is inexpensive doesn't mean it is a great choice.

So, take the time to read some threads, take the time to develop, and ask, some questions. The time for personal gear ownership will come. Good dive shops fully expect that customers will have done a lot of online research before calling /contacting them the first time. Use your background research to frame your questions.

Probably because I am used to buying online. I know traditional brick and mortar stores have limited floor space which limits what gear they carry and how often it changes. Also I find at the LDS you get that stores preference and what they prefer to sell. I like to look online and do my own research. I may come back to the same product or maybe something else.

At the facility I teach out of when a student purchases a bcd,computer , regulator , those 3 items, we take the cost of the course (academics and pool sessions ) off the price of the gear. So student gets the course for free this way. We charge $299 for the course here.
That should be a better deal than online.

Buy a drysuit, and use it right from the start. Just rent a wetsuit for the Open Water, or better yet do the OW dry if your instructor will go for it. You are paying a bundle for fun here any way you cut it, and the second and third cold-water wetsuit dives are just not any fun. Trust me on this. Get a simple bag-suit without insulation or stretch if you can find one that fits perfect, get a back zip if you have the shoulder mobility to get out of it yourself. Don't be afraid to buy used, do replace the seals if so.
As for instruments, If I were you I'd get a Sherwood Vision / Subgear XP Air. Not the best or the cheapest, but pretty solid and very compact.

The decompression algorithm is based on Buhlmann ZHL-16C, like many other proprietary algorithms. I have communicated with Deepblu and they were unwilling to share their NDL table with me. I have no idea how their algorithm compares to other proprietary Buhlmann algorithms like Pelagic Pressure Systems PZ+. I find this lack of transparency lacking. I would be hesitant to buy this computer without this information. It may be better than RGBM computers like the pending entry of Deep6, but only information will allow divers to make an intelligent choice.

I think the dive industry depends on ignorance of their consumers

I was supplied 1st dive air NDLs from the dive planner of the COSMIQ computer by a friend who has one. The computer is a little more conservative than PZ+ for 1st dives. I have no idea how it handles repetitive dives. When somebody has experience, hope they will post

Depth PZ+ COSMIQ
60 48 48
70 35 33
80 26 24
90 19 16
100 16 13
110 12 11

Had a half day so snagged a Zipcar and stopped by Dive Right in Scuba. I must admit they where super helpful.

I walked out with a shurewood mammoth and shurewood octo setup. Also snagged a puck pro.

Looks like I got a got start.

Not at all surprised. Glad it worked out for you.

Well, I guess you 'gotta scratch that itch' - there is something particularly satisfying about spending money on gear.

I admit I totally wasn't planning on it. I really wanted to look but felt it was a good deal sought as well.
