Don't be so sure

I've thought the same thing.

We have one natural spring that's divable in Wisconsin. About 550' is explored and mapped by a friend of mine. All 550' is no mount only, and it's an absolute BLAST.

Ya go from backmount, to sidemount just to be able to check out some of those smaller caves, next thing you know you are turning your head sideways because your skull won't fit through a restriction otherwise, especially with a big old regulator in your mouth..hehe. It's all fun
