What's an "upgrade"?
With my gear, if I am happy with how it is working for me, I don't think about replacing it. Sometimes, I'm not aware of how a piece of equipment might work BETTER for me, and once I learn, I change something. If something has qualities I find annoying, I keep looking around to see if there is something out there that doesn't have those qualities, and if I find it, I replace the irritating item.
For a couple of examples: The jacket BC I use in the pool to work with students will allow the tank, if I go head down, to slide up my back and clonk me in the back of the head. That wouldn't last long for me in open water. I'd find something that was more stable, or had a crotch strap (and in fact, what I dive in open water is and does!). The backplates I use in open water have the top slots too far apart for the width of my shoulders, and I have to cross my straps to keep them from falling off my arms. Until recently, there just wasn't an answer to that one . . . now Halcyon has a small plate with the top slots much closer together, and I WANT one!
