I was doing some reading and came across the terms Low Volume and High Volume
masks. I could not find an explaination about these terms and the difference
between each type of mask. I would appreciate some help with this question....
I am relatively new to scuba so I really want to learn as much as possible.
Thanks....

Google search brings up the following glossary that might be helpful to
you:

http://www.diveadventures.net/planning/glossary.asp?OpMode=List&Key=ALL

Here's their definition of "low volume mask":

"A mask which has a smaller area between the glass and the diver's
face, usually with separate lenses for each eye; requires less air to
purge if becomes flooded."

Less drag, especially in current, might be another similarly
insignificant benefit. Not something of concern to most divers, IMHO.

Personally, I like my high volume mask because of its greater field of
view. That, and fit, is far more important to me.

HTH.

It refers to the volume of air contained in the mask.  In practical
terms, it's how far away the glass is from your face when you wear the
mask.

Great answers guys.  I personally like the ones with one single lens, rather
than two.  I have better field of vision.  For the low volume, I find the
slight amount of drag there can be is negligible.

Thanks for the prompt answer...it was a great help. I like my 2 lens mask
because I can have my reading Rx (bifocal blind from old age) in the lenses.
I also now know that I have a high volume mask. Thanks RG

Low volume low profile masks are really for snorkel diving as the mask
hogs less air from your lung as you descend. A low vol mask also takes
very little water to flood it.

A high volume mask is more suited to scuba. A little bump and leak puts
water in but will not normally flood it the same way a low vol mask
does

I always carry two masks on a trip one snorkel one scuba. If I loose or
damage the scuba mask at least I can make do with the snorkel mask and
vice versa.

 I'm glad that works for you.

 I have almost ten years of diving on a low volume mask.

And why am I not impressed with almost ten years of diving?

You're best able to answer your own question.  For a nine year old, that's
his or her entire life.

 No one asked you to be impressed, or cares if you are.

 But since you brought it up, nothing about you is impressive at all, to
date.

 I take it you stand corrected on who addresses who on Usenet, since you
responded to this post.

lack of experience, judgment, and understanding?

you talk too much, and listen too little.

This is spam.... wise cracks all around but nothing useful to my original
question. It only serves to prove that you can be a diver with a lot of
experience and still not have a clue as to how to be a civil human being!

I don't know what information you've gotten so far, but some of it isn't
particularly good.  Here's a few things that may help, or not.

1. If you've been snorkeling for a while, chances are that whatever mask
you've been using will work well for diving too.  A mask is pretty much a
mask.
2. If it fits you, a low volume mask is usually better than a high volume
mask.  High volume masks contain a lot of air.  Air is buoyant.  They tend
not to stay in
   place as well unless you tighten the strap down to the point where it
may be uncomfortable.  They tend to leak more easily, particularly when
you're looking
   up.  Low volume masks, with the same lenses and dimensions, will give
you a broader field of view and are are less likely to leak or leak as much.
3. Your mask, whether for diving or snorkeling, should have tempered glass
in the lens(es).  Plastic lenses, for some reason, tend to fog up quicker
and are a lot
   easier to scratch.
4. I prefer two lens masks over single lens masks.  The two lenses allow the
mask to flex a bit more, letting it fit my face better.  They also provide
space for the
   nose piece/pinch without increasing the internal volume.  If you wear
corrective lenses, check before you buy.  Several manufacturers make off the
shelf
   perscriptoin lenses for their two lens masks.  They can be bonded to
single lens masks too, but not as inexpensively or as neatly.
5. Unless you just have to have one, avoid masks with a purge valve.  They
are prone to getting things tuck in them, causing a leak and tend to be the
first thing, or
   place, that fails, particularly those that are below the nose.  Pinching
the nose for equalization tends to stress the soft material around the hard
valve.  If you get
   one, check out the ones that are mounted in one of the lenses rather
than in the soft part of the mask.
6. Look for a mask with a double seal.  They're very common these days
because they work.
7. Fit is everything.  Take a regulator or snorkel mouthpiece to the shop
with you when you shop for a mask.  The shape of your face is different with
something in
   your mouth.  This is particularly critical if you're considering a mask
designed to give you a greater than normal vertical field of view.  They
give the improved
   view by changing the angle of the lens(es) and by bringing the bottom of
the mask closer to the face.  The closer it is to the face, the less
material there is to
   adjust to slight irrecularities in the shape of your face.  I've bought
two and gave them both away.

I use a Tusa Liberator.  Divers Direct (www.diversdirect.com) sells them as
a kit, complete with snorkel, for less than you're likely to pay for most
popular brands.  They fit me well and, in the 1 years I've been using them,
I've yet to have a single problem.  They work for me.  YMMV.  Make sure
whatever you get fits.

 Looks like she wasn't impressed that you weren't impressed.

Thank you for the information. It was a great help. I was trying to learn as
much information as possible. I have Snorkled for years but just started
scuba 2 years ago. Now I want to know more and more and more... Thank you for
your help. RG
