Best place to buy doubles?

[simbrooks]

Thanks. I can't see a sitaution where I, as a recreational sport diver, would need that kind of a set up, right? Thanks alot for your help. What I saw in the shop was two tanks conected in a Tee to one first stage

There is no harm in asking, furthering your knowledge, and defining your boundaries. No i cant see many rec diving applications for doubles unless you are used to them and hate diving singles (does happen occassionally with me now - certainly on shore dives or anywhere with a hike involved!), in fact this weekend it felt strange to be back in a wetsuit and single tank rig again.

uh, a hike and diving? Hike before or even after a dive is not a good idea.

This sounds over my head, or diving experience. Can a person put two tanks on with a standard BC? Do you need two spaces in back for two tanks? So, the sport diver realy has no need for this kind of diving setup? If my NDL is up it doesn't matter how much more gas I have, huh?

Most standard bc's are not designed to work with doubles. They lack the support and stability to handle the extra weight and width. Most divers using doubles switch over to the backplate and wing combination for bouyancy control and tank mounting. You can do a search on this and find more info on SB. There are some manufacturer's that have bc's that will work with smaller doubles. I won't go into that here, as there is plenty on SB. These manuf. would be the likes of Scubapro, OMS, and DiveRite.

The sport diver, depending on their profiles, can benefit from a doubles setup. The redundancy and extra gas can come in handy depending on your gas consumption at depth. Typically though, a 100cf single with an h-valve fixes most of this. The cost of reconfiguring your gear and the added weight/stress put on your body above water to dive redundant equipment reduces a little from the reward.

If you are easy on the air consumption, and you just want more safety, I'd recommend adding an h-valve to a 100cf tank.

I think he referring to shore diving and cavern/cave diving where it is sometimes neccessary to kit up a distance from the water.

Got it in one

I do take a little rest in the water though when i can. Some people cant even take a 1/4 mile swim out (with fins) to some of these dive sites. I would be happier jumping off a boat, but crawling back on in doubles is something i am not looking forward to!

I can't imagine walking too far in doubles through sand to get to the water. Man that would suck! I'll stick to boat diving while wearing the big guns.

Thanks. Think I'll stick with my setup for a while to come. You must need a cert to do these kind of double tank dives?

That doesn't sound like fun. It sounds more like work

To wear them get an experienced hand, no cert around that i know of. But to use them for their intended purpose (overheads) gets a cert

Well sometimes you have to work a little and put something in to get something out. Any rec or tech monkey can jump off a boat, most will even come back up, but only those with desire to dive will charge down the beach/through the swampy area to get to other out of the way sites. Of course some pay their dues the other way, getting down quick, but taking ages of mind-numbing deco to come back up again or taking several hours on the boat to get out to the sites. I'll take a little leg work, with some rest before the dive over a long boat ride and deco stops!

If you both go to the same dive site, you by foot, pack mule and weed clearing, he by boat, sunnying and relaxing, why would the boat diver have a long deco obligation and you would not? This is a trick questin, huh
