GoldGuy,
I was a real novice when I purchased my A52, still am, had it setup all wrong and it still captured gold for me but, it still works a lot better when it is properly setup!! Once it's been used for several hours and you decide to check see what's in it you must pick it up and then things can get interesting. It is long, awkward, heavy with water and cons and of course you are out in a river in amongst rocks and you do not want to spill everything back into the river. I found that by using the cross piece that comes on the sluice at the exit end and putting another in the area of the flare the entire rig is much more manageable to pick up.
Most people use a typical 5 gallon bucket for cleanouts but the A52 will not go all the way to the bottom of the bucket. After several uses of the bucket you may find that it will even crack, mine did. Instead buy a rectangular bucket, the blue recycle bucket at home depot, as it allows the sluice to go all the way to the bottom and no binding so no cracking. Also, have the bucket nearly full of water before using it as the entire thing will fall over if there is not enough water weight in the bucket.
The A52 is very sturdy and heavy, it is relatively easy to convert it to a highbanker, (casluicebox.com highbanker parts) but as others have stated the McKirk and other drop riffle type plastic sluices all work, each has its own setup needs, and they are worth considering.
Good Success with whatever you purchase..........63bkpkr
