What are the medical concerns for the following types of diving while taking Carbamazepine (Tegretol)? 1. General/Deeper (100ft - 130ft) diving like the Florida Keys? 2. Deeper (100ft - 130ft) diving in cold water (<40 degrees F)? 3. Underwater Search/Recovery Operations? A few...

You can't find a profile, because it's commonly called a "saw tooth profile", or a "bounce dive", and they aren't recommended by any agency that I know of. Many people in this thread have answered your question about the risks/safety, and have provided possible alternative methods for...

I've read back through the OP's post, and although he went to 100 feet, I can't see how he incurred a deco obligation. Per the PADI RDP Tables, the NDL for 100' is 20 minutes. The RDP says a safety stop is required for any dives to 100' or more, but isn't the whole point of NDLs to give a...

You say that you're wanting to enjoy the islands and a scuba trip. Which island are you going to? I just came back from a week on Ambergris Caye, and the diving along the barrier reef there is excellent. We used Action Divers for our diving, and had a great experience with them. You can contact...

I agree, your mindset and conviction towards safety and your training is very admirable. :cool2: I'm not sure if there are other dive operators where you're at, but if so, I would switch. As said before, you should talk to the manager of the resort, especially if the manager thinks this...

On the weekend of May 25th/26th, I was helping out with an OW class for my Nieces and Nephews at Haigh Quarry. I had my wife's regulators with me as a backup set, and I had pulled the Atmos-AI off with the quick disconnect so I could check the settings on it. I could have sworn it was on the...

Congrats on completing you pool work :cool2: There are more diving professionals (DM and up), shop owners, dive medicine experts, industry leaders, and manufacturers here on ScubaBoard than you will ever be able to meet anywhere else. If you take the time to look around, and read, you'll be...

I'm not sure how it calculates the usage, so I'm not sure if it's measuring your usage before you enter the water and actually "start" your dive? If it is, then maybe the spike is from filling the BCD prior to your entry. Or it could be the air you add to your BCD when you reach your depth...

Glad you're here to post about it. :cool2: I agree with dumpsterDiver and his point about needing a line/handle to do a safety stop. You need to be able to hold your depth for a stop without holding on to anything, and preferably, be able to hold depth with no reference other than a depth...

Exactly! When we're doing searches, whatever viz that "was" there is gone due to stirring up the muck. I have my Alt 2nd Stage across my chest and secured on the shoulder strap D-ring, and my computer is clipped to a retractor on my right shoulder strap. The pony reg is secured on the right...

Dangit! That was one of my first thoughts too, but then I got off on the DCS tangent. ;)

Ballastbelly - it really would be better if you waited until you've gone through your course material, and talked with an Instructor, before you keep running scenarios though your head and make yourself worried. Most of the questions you've posted recently will be covered in your class, and the...

Disclaimer: I tend to dive over-weighted due to helping with students, and also being on the county dive team where we're searching on the bottom, so I'm used to diving heavy, and not perfectly adjusted. When I go between a Steel-100CF and an Aluminum-80CF, I add(AL)/remove(ST) 10 lbs of lead...

Trim your mustache below your nose. You want to create a small strip of bare skin so the skirt under the nose cup can seal against it. Or, you can glob a bit of Vaseline in your mustache to seal off the same area.

I've got three scenarios. Which one fits your situation? 1. If this is a normal mask, then you would have to be exhaling through your nose to some extent, since this would raise the pressure inside the mask. When the mask's air pressure is higher than the surrounding water pressure, then it will...

Yep...just remember that you can actually breathe under water. Welcome to SCUBA diving. I think you'll enjoy being able to stay down more than a few minutes before resurfacing. :cool2: Also, don't be that "panicky diver" you posted about ;)

Well said :cool2: I just helped out with an OWD class where my two Nieces and two Nephews became certified. The youngest was 11, and the oldest was 15. They all did well, but had the typical new diver issues with buoancy, lack of confidence, and nervousness. All of which, are perfectly...

I took my Wreck cert with RR years ago and they were fine, but no recent experience. As far as online courses go, they still have to study and do the knowledge reviews, and there's still an exam. Our LDS also conducts one day of classroom for reviewing/reinforcing the material, then it's 1-2...

ballastbelly - I'm not sure of your experience/certification level, but when you work your way up through Rescue Diver, you'll learn all about handling paniced divers. As far as weeding them out during OW, I don't think you'll be able to make a good judgement call at that point in their learning...

I've got some top-side photos, and some u/w photos/videos, but I haven't gone through and viewed/edited them yet. Hopefully by this weekend. Here's a few pictures taken with my iPhone-5S to tide you over. 1. From the rooftop deck of The Blue Dolphin - What a view! 2. The last sunrise of our...
