Hi,
I am a new divers with only 10 dives. I had the pleasure of working with a good instructor for the last five and got some great tips on reducing my air consumption. I have reduced my weight (went from 24 lbs to 12), and stopped fiddling with adding air and letting it out of my BC for neutral buoyancy, reduced my drag and am more "tighter", and most of all am way more confident.
Taken as a whole, all of the above have helped me reduce my air consumption by about 200 psi per 30 minute dive. I think only more experience and other tips along the way will really help reduce my air consumption.
With that in mind, I am going on a trip to a lake this weekend. There will be 3 or 4 official dives and I hope to convince someone to do 2 or 3 shore dives. Air there is 10.00 a fill, and one must drop the tank off and hope that it's done when you come back in 4 or 5 hours. So since I am an air hog and want to do many dives, I am wondering what tanks I should rent. The tanks are 15.00 regardless of the size, so is bigger better?
We will be doing probably 3 boat dives and the rest shore.
I think for the 3 boat dives, I should get 3 super80 because it might be hard for me to get back on the boat. But for the shore dives, what about these bigger tanks? Are they just bigger and contain more air? Will they mess with my new found neutral buoyancy and require more weights? I tend to get very light at about 1,000 PSI on the 80. How much more time should I get (I think the biggest is 119 cu. ft)? They don't look to be much heavier 31 vs 40 lbs.
Any insight or advise would be appreciated. Google searches did not reveal much for beginners.
