Honestly my first bazooka was the 24 inch sniper and I love that thing. it's a beast! if I'd have known what I do know I'd have got the 30. but I love my 24. it's the perfect backpack sluice. light easy to use, and fits in my pack nicely. I don't need all the fancy equipment. internal external frames, bungies and so on. I load up my bag, pan. folding shovel,(works great with the sniper) crevice tool and Rock hammer for getting through some of the tough areas. Took me a couple tries to really understand the bazooka and these guys helped alot with the learning curve but all in all this is the best sluice if found. there's the vortex drop sluice but my god for the price and I hear there extremely finnacky. honestly I believe the bazooka still beats it hands down. for many reasons, weight, usability, holding onto gold, the vortex is supposed to make Tom's of little fluid beds so I don't think it's any different than a le trap or AM. Now there's the real vortex sluice that has a completely different idea and sounds like a great tool. then theres an underflow sluice. extremely finnacky, needs X amount of water to much it blows it out, to little doesn't work, X amount of material per hour and I'm talking a little amount the small one I believe is 3 gallons of material an hour to much it clogs up.
but the bazooka hands down the simplest and most effective sluice I've found. the way it works is completely genius. everything plays a part in that sluic. the slick plate. helps automatically classify everything, the abs plastic little bumbs gives fine gold a place to lodge and hide as most the heavy material goes buy before it gets pushed into the trap, the trap itself is genious. I have a video that help explain how that works, but the way the material moves in there acts like a catchers mit for heavy material and it can't get passed it cause it bulges up at the front catching everything and forces the heavier stuff to the bottom. it's truelly an amazing tool.
