[QUOTE="blisters, post: 230187, member: 4992"] My opinion is a stream sluice is a good migration step to a highbanker and you will always have it. I have a grubstake sluice and for me it is a little quicker than panning at 1/4" but it's not as physical as panning so you get a rest so to speak. From that perspective it makes the day a little easier. This sluice is good for small water flows and lower feed rates. If you go bigger then you have faster feed rates but need more water. There are other considerations such as slope as well to get the vortexes running and self cleaning. So it depends a bit on what your goal is feed rate wise and where you are going as to what sluice you can reliably setup right with angle and flow. To give an idea here is a vid of a stream sluice setup: [url]https://www.youtube.com/watch?v=0SY-dIPV7vI[/url] This guy is pretty knowledgeable IMO and this vid shows the sluice tuning parameters which he only gets right near the end. Near the end where he is feeding the sluice and not talking I would feed the grubstake at about the same rate but probably one fifth (maybe less) the amount of dirt. But it gives you an idea of the feed rate and flow requirement for that size sluice compared to a grubstake. You can also run a bilge pump to it if things are a little stagnant. Jon [/QUOTE]
