...and one detail that I forgot to mention :): The Number of Dives shown on the front screen of the MySSI App does not come from the number of dives in your logbook. This number is on your SSI profile, and can be updated by an SSI professional, it is usually updated when they issue a...

Hi Maartnn, Congratulations on earning your certification, and welcome to the great community of SCUBA divers! Regarding your SSI logbook, I'm not sure how it can be showing 1 dive on the front screen if either you did not actually log a dive yourself, or your instructor did not enter...

Probably Aquatic Specialties in Merrimack is your closest.

My recommended steps, FWIW: Option 4: You mean that you don't already own all of this??? Then Option 2: Get a drysuit and a ton of experience diving it at all depths. Paradoxically, it's harder to dive a drysuit in shallows than it is deep, but since this is where you will spend most of your...

Seems a bit excessive for a 45min / 45ft dive - Just an opinion.

Thanks for the clarification. You may not hear this often on Scubaboard... but I think that we agree :wink: Except, perhaps for "...how stupid I think the discussion is about using pressure/min". Since psi drop is the only thing that you can easily measure during a dive, knowing your...

Not making that distinction at all.

I think that you may have misunderstood this point, it is not that you are "technically in the second atmosphere", at 35ft you have 35/33=1.06 ATM of water pressure PLUS 1 ATM of atmospheric pressure giving you 2.06 ATA (Atmospheres Absolute). A lot of divers forget to add or subtract that pesky...

There are probably more than one way to do this, but here is what I do: 1. Descend to a known depth and shoot a DSMB (just for reference to help maintain a constant depth) 2. Record cylinder pressure 3. Swim at constant depth for a know period of time ( e.g. 10 min) 4. Stop and record end...

There is no problem teaching SSI Open Water using a backplate and wing configuration. A few skills, such as weight belt remove & replace, and SCUBA unit remove & replace are a little different (because the crotch strap needs to be dealt with). Also, because I use a single piece harness, I need...

All valid suggestions for practicing the mechanics of holding a deco stop, but the original poster also wanted to observe how his computer operates while in deco, which is not a bad thing to understand, so practicing stops achieves objective 1, but to achieve objective 2, Your suggestion of...

Genius

Highly recommend Richard (Ricky) Simon. Based in CT, not RI, but close enough to make it work. You can find Ricky at the link provided by @VikingDives in the post above.

I have not noticed any issues

Also holding back, and resisting the :poke:

Not sure I would agree with this. Physiologically, yes, they are the same process (regardless of gas being used - which just accelerates the physiological process), but in terms of the parameters of the process - vastly different. By definition, a recreational diver completing an optional (but...

For this course, the dives are planned as if the stage/deco bottle does not exist, i.e., the dive and deco obligations can be completed on the back gas. The stage/deco bottle is for an extra margin of safety by just switching the breathing gas or to accelerate deco by switching gas and computer...

White Gorilla Tape (sticks way better than Duct Tape) and the aforementioned Sharpie is good for most surfaces, including cylinder markings for Name, FO2 and MOD.

Remember that this is a RECREATIONAL course and so it teaches that an OOG diver would do exactly the same as he would do in a recreational OOG situation and share air with a buddy. Gas planning for this dive accounts for sufficient reserve to bring yourself and an OOG buddy up to the deco stop...

Standards say that the dive must be planned so that the entire dive can be done on the back gas. Switching to a slung pony for deco with up to 40% Nitrox is allowed. Long hose is encouraged but not mandated. A good instructor will help students see the wisdom/convenience of a long hose...
