What are your thoughts on Hole sizes of sand scoops, 1/2 vs 5/8

Has anyone added screen to the inside of of a scoop to classify down and catch smaller stuff like jewelry or sinkers?
Any tutorials or pic threads on adding stainless lips to aluminum scoops? thanks all.
Those that advocate smaller holes, so that smaller things (like earings, fine chains, etc...) don't "fall through" make it sound as if you will, "of neccessity" therefore, miss those targets that are small enough to make it through the holes. But that logic does not necessarily follow. Here's how:
a) you dig for something, and
b) deduce it's now "in the scoop" (because you scanned the tailings pile and there's no longer a signal there)
c) you shake out the contents, and look in the basket, and see nothing at all. Thus you deduce that the object was small enough to go through the holes.
Well duh, the solution is you scan the ground where you just let the sand fall through, and find the signal again. And THIS time, you bend over, and rake through with your fingers, to see what the little thing is. So you see, having holes that are large enough to let teensy things through, does not automatically mean you can never, therefore, find teensy things.
The problem with having a sand screen with small enough holes to catch teensy things, is that it makes it hard and strength-consuming to shake out the wet sand. Because wet sand is "clumpy", and you have to shake vigorously to persuade the sand to break up and get through the sifter, right? Well that need to shake it (and the resultant time and energy expended) goes up when your holes are smaller. And yes, other nuisance things like pebbles are there, etc.....
That is why most stock sand scoops have historically made the holes a little smaller than U.S. dimes (or half-dimes). That catches all the coins here in the USA (except perhaps a U.S. $1 gold), and catches 99% of rings (I can't imagine a ring smaller than that, except perhaps a babies ring). I've found that most of the stuff that makes it through is usually .22 lead shots, teensy brass screws, rivots, etc... Sure I check all the ones that make it through the screen anyhow, because you never know if it was some small piece of jewelry now and then.
