What duplicate items do you carry?

[BEM]

What items that are duplicates or backups, do you carry with you on dives (while diving), why and have you had to use it?
When you have a regular buddy, do you carry one extra for the two of you?

Some divers carry extra equipment: i.e. mask, cutters, slate, two computers, pony, tables,

I haven’t seen a diver without an octopus, so that is an expected part of the gear and not really extra (my opinion). Another given is: lights on a night dive.

I now have an extra mask and am thinking of carrying it on deeper (over 50 ft) dives. Wouldn't want to be without one if it got kicked off or the strap broke. Probably not chance of it happening, but I could keep it in a BC pocket.

Depends a lot on the dive, but the minimum for me includes
2 second stages
2 cutting devices
2 light sources (one may be the sun)
2 lifting devices (BC and lift bag, for example)
2 depth gauges
2 timing devices
2 "tables"
More complex dives will dictate more redundancy.

Analogue depth gauge in pocket and watch on wrist in addition to dive computer. Plus I'll write the dive plan on my slate if it's at all complicated.

I think of my slate as a back-up for those moments when hand signals fail me.

Always carry a sausage, but I count that as an essential part of my gear rather than an extra.

I take an extra mask, and spare parts of course. On night dives I always have more than one light

At other times, I just take both BC's and both sets of Reg's and all 3 wetsuits.

Just depends..... Rich :mean:

2 of almost everything.

besides an oct I carry:

1 AL30 Pony Bottle with reg and SPG (always carry the pony bottle, regardless of the type of tanks I am useing).
2 masks (had a strap let loose once, the spare came in handy that time. Put it on, grabbed my "good" one from the bottom and continued the dive.)
2 lights
2 strobes (when going deep and dark, or at night)
2 knives
2 depth guages (dive computer on wrist & analogue with primary SPG)
2 bouyancy devices (BC & lift bag, but only 1 safety sausage.)
1 extra fin strap in BC pocket (not much use on the surface if the strap goes while under water now is it.)

Thats into the water, on the surface it's a lot more.

I carry quite a lot actualy. A habbit I got while instructing people. Let's see-

-At least 2 knives, place in a way that I can reach with both hands.

-Two second stages (obviousely).

-Diafragm for second stage.

-One or two spare masks.

-about 5 o-rings.

-Analog deapth gauge in addition to computer.

-2 mask straps.

-safety bands.

Probobly some more I cant recall.

Very new to diving, but I carry extra o rings, fins starps, Basically a basic save a dive kit.
The other day we were going diving and my buddy couldn't find his mask. After looking and looking. I found one of my daughters Walmart special mask. He used that and had no problems. I paid something like 13 bucks for the thing.

Save a dive kit (straps, o-rings, etc.), weights, and allways use 2 computers (1 air integrated on console, other on my arm, whistle and dive alert.

How many of you have actually lost a mask? Are we talking about the spare that you take on the dive? I understand that DIR encourages a back-up mask. It sounds as if others take them on the dive as well.

My question is this: didn't we learn that we can dive without a mask? I mean, most of us learned to swim and opened our eyes underwater long before we learned to scuba dive. And how necessary is an extra mask on the dive?

It seems to me that an extra fin (while not practical) would be a better choice for a backup. It is more difficult to swim with just one fin than without a mask. I, for one, have never lost a mask (or a fin) on a dive.

Now, if you mean what do we take to the dive SITE as a back-up, that is a different question. It also is dependent on what type of diving you are doing, right?
