I had about 2.5 feet of vis at lake Georgetown today. Kinda chilly too.

Um... You can't safely dive deeper with nitrox. If you have a basic nitrox cert and you went to around 150, you would be pulling close to a 1.6 pO2 even using a common weak mix like EAN28. Your Equivalent nitrogen depth would be around 130-140 (rough estimate). When tech divers use...

This has been discussed in the general equipment section previously. The short end of it is that its ok to travel with the lights. Explain that they are scuba lights. They may want to see the batteries. Also - dont say it looks like a bomb. Dont even say bomb.

Well I'm sorry. I didn't know Kevin Gurr was bringing it into the store and my phone wasn't with me. He said that he should have pictures up on the website soon. Scrubber uses either cartridges or regualar sorb. He told me that you could get a duration of around 110 minutes at 100m with...

I just got to see and touch the new Sentinel Rebreather tonight. Really nice design. Looks like it has a lot of the good things from its big brother but not with the extra $$$$$ Axial scrubber. Poseidon first stages. Interesting sorb monitoring system. O2 calibration system. Etc. I've...

From my understanding the dive shop is right. You didnt state earlier that the elastaprene was merino lined (I believe Pinnacle makes both types.)

Here is a link to one approach for rigging if you are diving a backplate and wing type of BC. At the very least, it may help with some ideas for your gear set up. I don't follow the entire philosophy of these guys, but they do have some good gear configuration...

sherwood avid snorkel.

If you are just going down to cozumel and whatnot a few times a year, your selection will probably be fine. A lot of people on this board - myself included - prefer some sort of back inflate BC. They may not always feel as good in the showroom or hug you at the surface, but they are...

I use a plastic Sherwood spg from 1989. It goes up to 5000 psi and has never let me down. Does that make me a bad person? Would people like me more if my spg were made out of brass and glass?

Mine was two three hour classes in the evening for around 6 weeks. One was classroom and the other was pool. It was a YMCA class that was probably a bit more intense than today's classes from what I hear. This was also back in the day before safety stops and before 60 feet was considered...

wrap the hose around your neck over and over again until tight. place the regulator in your mouth and bolt snap the end of the hose to your snorkel. alternatively, you can route the hose downward from your firs stage on your right side and around a bellows pocket or canister light, tuck part...

I've used thumbs up for abort the dive. Honestly, I really hate this sign as it can mean so many things to different people. "Good job", "ok", "ascend up a little". When I am diving with my friends, we have a very unambiguous signal for abort the dive: One hand extended and bent up at...

I agree. DSS has good prices. Also, I purchased a backplate from hammerhead and a basic oxycheq wing from scubatoys. Added the hardware and webbing and the whole thing came to around 350. As far as actual bcs that accept doubles - I believe the Zeagle ranger does as does one of the oceanic...

After all the lectures about oxygen toxicity in my advanced nitrox class, I'm wondering if anyone here has actually had oxygen toxicity. I've had a pO2 of 1.6 on sufaded with no symptoms. Also, I remember seeing a picture of a guy in the early days of diving (1940's or so) where he went to...

I did a double take the other day, but saw a diver with the long hose, the bungeed reg around the neck and an octo inflator on the wing. Seemed like overkill to me, but the octo inflator really wasnt that large and the diver would have already been running a lp hose there for a regular wing...

Any well known brand of regulator is going to treat you just fine in the warm water sport diving arena. Cold water may mean that you will want environmental sealing to keep your first stage (the part that screws on to your tank) from forming ice. The down side of envoronmental sealing is that...

Regarding your fear of blacking out. Try this while sitting at your desk. Exhale and wave your arms behind your head for a few seconds and then touch your mouth. If you haven't blacked out after a few seconds, you have the physical ability to locate your regulator and stick it back in...

I just have a button spg for the first stage. Always check my pressure before jumping in the water....unlike those spare air testimonials.....:D

This whole debate is giving me a headache - which could easily be solved by taking 500 mg of tylenol and a half litre bottle of diet coke. Actually, this headache could be caused by the .750 litre bottle of wine I had last night. No, its probably because this damn laptop is too slow. It has a...
