Hello Ben Cartwright SASS,
What a fine hobby you are about to take on, especially if you purchase both units as you've hinted at! First, Hello I'm 63bkpkr/Herb and its good to type to you and I own an A 52 that I've added a californiasluice.com Highbanker to. I've used the A 52 on rivers in California and have several comments concerning it. First ALL sluices have 'best methods of operation' including the A52 as well as any of the McKirks. For either you need just enough water to go over the riffles, do not bury the sluice in the water all the way up to its sides, this will keep it from working properly. The A 52 needs more water flow than the McKirk though too much water for either and you will loose gold and maybe especially with the McKirk. Any of the McKirks are lighter than the A 52 then again I can and have dropped my A 52 and it just gets a bit rough while the McKirks are well made but theay are plastic so a bit more care is required with them. The
A 52 is carpeted as that helps to hold stuff as well as some expanded metal inserts do as well and of course the heavies hang in behind the metal riffles. ANY sluice is a bit delicate to pull back out of the water as now it has water in it as well as stuff you do not want to loose so holding it properly to not have the water empty the sluice as when you stumble while walking the sluice back to dry land, yes this happens. I mounted an additional cross bar on my A 52 and that along with the built in handle help so much for the lift up out of the water as well as the carry. I've found gold with the A 52 but the cleanups, when you do them, are a bit of a hastle as they barely fit into a 5 gallon bucket and then if one is not careful you can split the bucket with the metal edges of the sluice. Tip, do not use a standard 5 gallon bucket buy one just a bit different in shape than the round 5 gallon bucket and then the sluice will go all the way to the bottom of it. Oh, be sure you have the bucket about half filled with water so it does not tip over on you as it will if it does not have some weight in it.
On Tnet back in the September/October Sluicing files of 2010 you will find several 'help' posts I made as well as the wonderful responses I received, even a video of what it looks like when a sluice is setup properly (the water makes crisscrossing X's as it goes down the sluice) lots of good pictures and comments.
I hope some of this random stuff is found to be of some use to you and I wish you the best of luck in your endeavors.......63bkpkr
This photo is the gold I found using the A 52 along with my GMT, about a quarter ounce, the first season I used a sluice.
