I would say easily. The attached photo is on a 6.9 diameter steel 72. Larger diameter tanks have even more room.
Unrelated to merxlins question:
I tried to get a photo of the Highland bands latch with the tank in the horizontal position. It is hard to see, but notice that I can latch it one-handed. I can be done vertically, but one-handed takes more skill than I have.
Thanks Akimbo. Looks like DSS will be getting a few more $ from me.
Regarding the Highland bands- once you hook the cam into the metal loop, do you have to take slack out of the band and tighten it up before closing the cam buckle? My issue was that if they are tight enough to hold the tank, they are not loose enough to unhook from the loop. The advantage of the Scubapro style is that they are set for size, you just unlatch them, and when you replace the tank they are already adjusted for that tank.
