Divemasters is where I would send you. Large pool onsite and great instructors. If the $800 is for both students, it would be reasonable, for each, it's high. Mike

Aggressive, since the 3rd dive is pushing the CNS over 100%...not something I want to mess with. 185 on air is within the MOD, and we all regularly push other mixes to near the MOD, yet for some reason going there with air is "crazy." Are there better gasses, sure, but you need to take another...

There are two levels of NITROX. Level one is to 32% and doesn't require dives. Level two is to 40% and requires dives. Level two would count towards AOWI. Mike

If the specialties appeared on your card, your instructor is certified to teach them. The system for ordering cards won't let an instructor order cards they aren't certified to teach. Mike

Tammy, 6:1 is actually an increase, since it used to be 4:1. OW class still has restrictions of 8:1 (10:2 with certified assistant) and 4:1 if you have juniors. After many sessions of try scuba, I think these ratios are reasonable, and especially with young kids, 2 is more than enough to...

I've been to CCV twice, and I'm already looking at the budget to figure out when I can go back. Absolutely the best dive operation I've been to. If you are looking for serious bottom time, it's possible to get in 7-8 hour long dives (on NITROX) if you want. 1 before breakfast, 4 boat, 1 or 2...

I would focus the dives on planning using the skills taught in the class (Analyzing, setting computers, dive tables, repetitive dive planning, CNS clock, etc.), with the idea of reinforcing the advantages and limits of NITROX. This is also a good time to do a review of basic skills that many...

SSI has 2 NITROX certifications. The first is to 32% which is classroom only. Dives under this cert must be planned using air tables, and are limited to 100ft for 60 minutes. The second is to 40% and requires 2 dives, which allows it to be used for Specialty Diver, AOW and Master Diver...

Or, as my instructor from long ago said, get up to the pro level, and your number is only 5 digits long ;)

I came up to Divemaster with the PADI system, including multiple specialties. I have specialty cards from PADI, NAUI, ACUC, and a couple others. When I decided to become an SSI instructor, I picked up where a DiveCon would start, and had no issues. For specialties, it was easy to pick those...

I've normally taught Night/Limited Vis, Deep, Nav and Perfect Buoyancy as the "standard" grouping. First off, this really gives a great group of classes to flow together and build on each other. I have also been able to notice a huge improvement in skill as the class progresses. These classes...

Love it!

Wil, Thanks for the info, and I'll have to check them out once I get my dive gear back from household goods. :depressed: This is going to be a long few months being dry. Mike

Sounds like a good time was had by all. Can you post the info about the charter operation. I tried to google it with no luck. Mike

Tech divers may buy stuff online, but is that because they don't want to support a local shop, or because their local shop doesn't carry tech stuff? I know I always try to buy from a shop, and will only buy online if I can't find something at the shop. Maybe it's just me, but I like to...

The only thing I can think of that might cause the difference in feeling is that when you flood the mask, it's normally intentional. If you know it's coming, you are prepared, where a sudden major leak not only has the cold factor, but the surprise factor as well. Mike

Great thread, with tons of good tips. So, a couple that I've learned along the way: When deploying an SMB, make sure it's hooked to the line, not to the bolt snap on the handle attached to you... With all of the "dry" snorkels out there, this is one I've had to use frequently. Often the...

Ok, now that kind of diving would be worth the long ride out. Mike

Maybe the Israelis will oblige...

And here's one for SCBA to DIN
