Hey why don't you two go have your bitchfest on a thread in your area rather than bringing down ours. We all get a long here and don't need anyone coming into our little world and starting ****. Keep it to yourselves. Do it via PM's and not on our thread.

EAN I don't want to spend more than about $100 on a light. I don't get ino the dark that much.
 
Now that we have that settled lets go back to the original posters question, shall we?
 
can anyone here point me in the right direction so i can log some 100-130ft nitrox dives......need to get some logged before i can take some of these deep courses....thanx in advanced

Assuming your in the "Tampa area", The first issue you'll have trying to accomplish this on the West coast of Florida is that any dive deeper than 100' is either 30 miles off shore, in a cave, or in a sink hole.

As far as Gulf diving is concerned, if you have about $100.00 to spend, get in touch with "Capt Ty" on this board. He runs trips out of St. Pete and 30 miles out for about that price.

As for sink holes and caves, Looking at your profile, I wouldn't recommend it. The four deep sinks and caves in the area are advanced cave dives ( whatever that really means ? ), and unless you have some experience in those enviornments and feel comfortable working in deep dark water with low vis, you can get into trouble very quickly at all those sites. Not to mention 2 of the sites are fragile and easily damaged by divers.

As for a Nitrox mix. In the real world - I've used anything from 28% to 30% between 99' and 131' and never had issues. Others may preach different mixes for their own reasons. On paper, IANTD style - if you want a PP02 of 1.4 at 4 ATM's 35% will do you. If you want a PP02 of 1.4 at 4.9 ATM's, 28% will do you.

Hope that helps.

Dave.

I hope you don't mind if I butt in on this, too late if you do, INOVA makes a very good light for about $55, rated to 400' and is very bright (much more that larger, more expensive lights).
 
I don't agree with this at all.
We use 30% for 120 feet, with air your bottom time is 13 minutes, with EAN 30% its 19 minutes.
That is just about a 46% improvement.
Then add the fact that you off gas faster on your safety stops.

There are a lot of good wrecks in lake Erie in the 110-130 foot range.
We dive them all summer long.

True, but there are better ways of diving those ranges than just adding oxygen to your mix. Personally, I'm not going to 120' to spend 19 minutes on a wreck. I'm going down there to spend as long as I need to and bring the appropriate amount of gas and deco gas to come back to the surface safely. And based on the OP's experience, I don't think doing dives to those depths just to log them is prudent. That's why I asked what I asked. But the OP hasn't come back with a response yet...

Thanks. I will check them out.

It depends where you're more comfortable, but fresh water dives like Hudson and Hal's 40 Fathom are cheaper and easier to schedule. Being a confined 'hole' it's also easier to get help if thing go bad.

Light
Well, at a $100 you're in the 8-cell category. I'd try to find an LED model as they are the future. I think the UK 'Light Cannon" 10w HID can occasionally be found on eBay, but the bulb is nearly $100 alone. I personally have an old 8D UK, but never use it since I have moved to a 10w canister light ($300 used), my LED back-up lights are Princeton Tec Attitude ($20) & Impact XL ($35). There are also some interesting 2-3 cell handhelds like the OMS Vega & Scubapro Nova.
