There just isn't anything much lighter out there than a 720. My buddy that has one of those Ukraine Stavr knockoffs that I have used is lighter than my Stealth - but only because its a smaller scoop. (I actually wouldn't mind getting one of those). I was falling apart as well and that is why I bought the 720 and the CF handle. I was having some pretty bad issues with my left shoulder because of digging. I saw the trainer in my school and did the therapy he recommended plus I also started a resistance band workout that I did for about a year focusing on my shoulder. No more issues. Recently, I restarted strengthening and conditioning my core because I'm 54 and I realize that its important to get to old age being as strong as you can get. As we all know, water and wet sand hunting is not for the weak and I want to be able to successfully detect as long as possible.
