Heres one I made out of an ice scoop, alumaweld, and some scrap aluminum plate....I'm a woodworker, so I applied those skills and dovetailed and, keyholed everything so it all holds itself together even without any welding skills. The alumaweld joints have since broken off, but the thing is all locked together anyway and is solid and works just fine I alumawelded the tip and that is a good idea, since the alumaweld is tougher than regular aluminum......I cut everything with a Jigsaw and a metal blade as well as a hacksaw, drilled the holes easily with a regular old 3/8 drill with a 7/16 drillbit I think...it took me a few hours, and has held together for 3yrs of HEAVY use now... I bought two ice scoops for less than 30 bucks off some internet deal that caters to restaurants and this kind of product...I believe they are 54oz? Anyway, for my use in deep fine Lake Mich sand it has been working very well...I can see why the Pro mfgs get the money for a good scoop though...lots of engineering and balance involved, and theres a lot of different types of bottom a guy has to deal with. .this scoop would probably not be the thing in rocks or heavy clay, but for gravel, sand, shells, its fine... my crappy looking scoop has some benefits like the long shallow basket, where a fellow can see right away whats in it and not have to dig around in there with your hand, or pour the contents out in a sifter, If I bounce it a few time under water the shells and light stuff float right out.. I dig with it as if it were a hoe, and can really excavate a nice hole even in fairly heavy surf before it can fill back in...deep targets on the dry I chop with it like it was an axe, most shallow targets are just simply scooped up with a sweep of the arm. A guy would build this without any welding and use some screws in strategic areas I suppose. That long vertical piece is keyholed through the horizontal piece, drilled to fit around the ice scoop handle, and then with a pair of U bolts, attaches to the wood shaft...that flat horizontal piece is countersunk into the scoop, and you can see how I keyed it into the sides of the scoop to really lock it in there good...without doing this, the whole thing would have broke up long ago as the Alumaweld does not hold at all very well in high stress areas..
