zeagle ranger twin tanks

Can anyone give me a list of items I need for my ranger to hold twins?
I will be doing twin independents, So I just need to know what I need to mount them?
I looked about, and got two different results. One small bracket, and one massive expensive one.
So I am lost. What is needed to hook them up to the BC?
Also Is there a good way to hook two tanks to the BC inflater without a bertha?

If you are going to dive doubles, the best way is most likely a bp/w. One of my friends looked at attaching doubles to his bcd but it was sketchy at best. The tanks didn't seem secure and the bcd moved around too much to have any kind of decent trim.

However, if you're set on sticking with the zeagle ranger with doubles I'd do a search. I googled "zeagle ranger doubles" and got a ton of responses

You can either do the Brackets/Bladder Attachment straps or the Backplate.

Parts needed are detailed in this video. Sound is bad but here's both options:

So basically for option one you need the brackets and the bladder attachment straps.
For option two all you need is a backplate.

Plus bolts and bands for the tanks for either option.

Here's all the parts for option 1:

Or option 2:

Notice that on both installations, when he tightens the wingnuts, the twins are already banded together on the other side of the BC.

Obviously the Backplate is a better mounting also since it's a lot stiffer.

You might price other bands also. $255 seems kind of high to me. A good set of Highland bands are $144.

You may need some help determining the correct location for proper weight distribution also.

I can't answer your last question.

Thanks for the answers, and the video.
I am a bit confused, did the normal tank straps need to be removed when the backplate was in use? or did it just bolt on over them?
I recreational dive only once every few months, but I dive to clean boat bottoms weekly, so I need this conversion to be reversible and not too hard.
