We can get Nitrox off site at the moment but they will only fill the cylinders to 3000 psi, not the 3500 psi for the 100 cu ft steel cylinder, making is essentially an 80. We usually get it for the deeper dives to increase bottom time at depth but not for every dive. I have plans to add a...
I am re-thinking my "Save a Dive Kit" to maximize functionality while minimizing weight and space. Yes, airlines are involved and at fourteen pounds, mine is too heavy. :( I would love the hear what everyone considers essential in their "Save a Dive Kit".
I am very concerned that we may be taking too much risk using Scuba cylinders for oxygen. Industrial cylinders have a threaded steel cap that protects the valve completely preventing any accidental turning during transport. The O2 bottle in my DAN kit has a removable hand wheel that makes...
I would like to add one other thing to consider. Your breathing patern is very important to avoiding panic. Most open water divers breath shallow and from the top of their lungs. The thought is I must have air so I will keep my lungs full of it. That is why open water instructors stress that...
Very Well stated! I have never had a bad PADI instructor either. All have been 1st rate. So much so, I became one myself.
Most people on this board simply judge the training PADI requires for open water to not be sufficient. This may be true. PADI believes in continuing your training...
I veiw streamlining as not jumping into the water looking like a christmas tree with ever possible gadget or tool hanging from you BC like an ornamant. If you don't need a snorkel, leave it on the boat. If you don't need a line and reel leave it on the shore.
If you diving in the open...
I feel that the flutter kick thrust is backwards and slighly down relative to a horizontal diver. I personaly compensate for this by triming weight so that my feet slightly above my head. This also has the benifit not stiring up any silt on the bottom.
Thanks for the advice. I found the reef photo review and the HG20DX does out perfom all the rest by a wide margin (pun intended). Here is the link to the review Reef Photo & Video Support Center - KnowledgeBase - Focus Lights - the Good, the Bad and the Ugly Focus Lights - the Good, the Bad...
I have a Canon 300D with ikelite housing and strobes. The camara needs a light to focus with at night. Does anyone have any recomendations for a good light to use? Would a video light work well here? My current lights have too narrow of a beam and the produce a bright spot in the picture...
Thalassamania,
You are correct. Doing anything that exposes one to any risk of injury is dangerous by the strictest definition. Walking down the street is dangerous. You could be hit by a car.
You may not care about my belief system, but ther are those who do. Some of them read this...
It should take 30 seconds to ascend from 15 feet.
True, slow deep breaths should be taught.
I am glad you brought up stress. Stress in a student can show up at anytime any where. This is an important fact for an insturtor to believe.
Yes we break the teaching process down into small...
Sure I thought about my response. Did you?
What does depth have to do with CO2 build up and the desire to breath? The student could have been CO2 loaded from breathing shallow long before he ever took the regulator our of his mouth. The stress of just thinking about having to do the drill...
It is simple. If the CO2 in the victims blood caused him to have an overwelming desire to breath in mid water, without the gear the victim might panic and bolt to the surface causing the air embolism. With the gear, he could stop the asscent in mid water and take a breath from the regulator...
