What is this for on tank bands?

[Super]

Thanks for all the feedback. I'll probably cut and file down the edges.

Dive safe and dive often.

Those bands as Luis said are for the plastic back plates common up until ten or fifteen or so years ago. Those plates had a center groove (depression or tunnel) to accept a single tank. Funny that these old plates used an adapter (built on to the bands) to adapt doubles to a singles plate and modern back plates use a STA to adapt a single tank to a doubles plate.

Now, curiously, several back plate manufactueres are experimenting with cut down (modern) backplates that look alot like plastic plates used to look except they are metal. N

For any that care, here is a photo showing the same style bands on a plastic backpack.
I got the photo from a vintage dive web site.

Quite the job finding that picture Gilldiver!! A picture is worth a 1,000 words. Thanks.

Appreciate your effort. I'm on my way to get the "extra" bands cut off in about 1 hr.

Thanks again.

Same kind of bands I used when me and Jesus used to dive together 2000 years ago.

Diving with 7 year olds, eh? Real nice.
