Planning a day at Ginnie Springs with some friends diving and snorkeling. Only problem is I am the only certified cave diver in the group and if I am going to be that close it would pain me to not get an hour or two in the caves. Ultimately I would also like to dive with my friends in the...

I am selling my Hollis SMS 100 not because I don’t like it but because without my drysuit I am too heavy in the feet. It is size XL and none of the straps have been trimmed even though they were more than long enough. Only used like 10 times always in fresh water. Has a loop bungee modification...

I have an OMS manifold with an isolator that I used on skinny neck tanks. No longer need it but I had within the last 6 months been O2 cleaned as well as new packing placed in the valves. I paid $120 for it if at least like to get $100 out of it. I’ll post pictures later this week after I dig it...

So I have a friend who has always wanted to dive and has recently made some major life changes. As a good friend I told him that when he was ready physically I’d get him equipped and certified to dive. I have most of the odds and ends but I am still looking for a backplate and a reg for him...

I have 2 HP 120s for sale propper 3500psi tanks. Out of hydro since July still have around 2k psi of nitrox in them. Also have an OMS isolator manifold recently O2 cleaned and tested and a set of bands for them. Great tanks just not ideal for me anymore. Looking for $450 for all of it or a...

Right now I am considering selling my current tanks (I have owned them for the last 15 years and they belonged to my Dad before that) not because in some way they are bad but not ideal. Being the old 3500psi steels they are HEAVY I dive dry and need 0 weight in fresh water. However that also...

After opening up and cleaning my G250 it breathes better than ever however only gives a few feeble bubbles when the purge is pressed. Everything went back together like it looks like in the manual and the purge button on the face LOOKS like it's pushing on the diaphragm. Any ideas of what could...

I am not a decompression diver by any means, but as a nurse when we have cardiac patients with decreased perfusion we give aspirin to thin the blood and help to increase perfusion. So by that thinking would taking aspirin predive help to facilitate more efficient offgassing and buffering against...

I currently have a matched set of HP120's that I'd like to manifold into doubles. I'm 6'2" and 340lbs so they wouldn't be too big for me. The trouble is they are older skinny neck tanks and nobody I have spoken to knows where to find a manifold that will fit them. If anyone knows where to find...

Help! My dive buddy has had to cancel on me and I need someone to dive with. Just got my new BC (Hollis SMS 100.) and need to play with it and figure out my trim and tank placement. Is anyone available to help a guy out and just putz around?

So I've decided to take cavern/intro and there are gear requirements that include a primary and a couple of backup lights. What makes a primary light? I have a few cheap Chinese dive lights that if you believe the packaging put out 6k lumens and 10k lumens for around 120mins and longer on lower...

I know that caves are dangerous and should not be attempted without proper training but how does someone know if they would like it enough to spend the money? I enjoy diving in springs and looking at rock formations and I think I'd be interested in exploring some caves nothing too intense...

Hello there, not sure if this is the right place for this but I am heading in the tech direction. Currently certified AOW and nitrox wanting to further my skills and looking in the future at AN/DP helitrox for extended bottom times in the 160-200 foot range. Short term I want to get up to do the...

I have been diving for about 10 years and am currently thru my advanced open water with nitrox and have a potential dive buddy who is looking for a class around us. We are both unhappy with the offerings at the local dive shops as they all seem to be pushing gear and trying to upsell personal...
