Moving sand underwater, does anyone have pics of equipment being used?
I was wondering if you guys can share some photos and suggestions for moving sand underwater and show some of the devices? I would love to see them to get a better understanding of what is being used these days. Salvor 6 if you are reading this could you show some photos and who ever is interested in reveling some of their little tricks of the trade. I am just trying to find some options to help me find more gold underwater since it sinks to the bedrock. Thanks for everyones help and I wish I could be there finding the good stuff on the east coast!! Thanks

Here is the link to a video I filmed of Darren and NCBrad working a hit on SEAHUNTER's Jupiter Wreck. The Scooter is indispensable in blowing out the crevasses where coins may be hiding beyond the reach of the detector.

Salvor 6,
The airlift that you show in the post here. I remember you posting it before and was wondering exactly how it works. I do remember that it is connected to a scuba tank though. If you could, could you please direct me to the post where you provided all of the details for building it? If not, could you PM me with the specs and details? Looks a heck-uva lot more efficient that a scooter for moving sand.
Re: Moving sand underwater, does anyone have pics of equipment being used?
The air lift is a 2" PVC pipe, about 6' long with a 2" wide aluminum sleeve. The sleeve is hollowed out in the middle about 1/4" from each end. I then drill about 50 to 60 small holes all around the pipe. Inatead of one bog hole going into the pipe I have 60 small holes. This makes smaller bubbles that expand faster. I also drill the holes at an angle to create a venturi effect. This makes the dredge act like a lot larger dredge. Here is a closer look. If you go back in the shipwreck forum and search for the "Mailbox" thread you will find the earlier posts. I'm not going to search for it.

Salvor 6 if you are here can you reply to this subject. At what depth does the airlift start working properly? Can I use this in shallow water or does the water have to be at least 20' deep? I wanted to use this in water that was shallow like 6-8' deep, I have a place where I need to move lots of sand any suggestions. Thanks

Makahaman an airlift dredge will not work in shallow water. You need to get a suction dredge like the Keene dredge. It can be mounted in a small boat like the one pictured below.

Salvor6, can you post a pic of your "sleeve"? I can't figure out exactly what you are describing. The only thing in you pics is the PVC tube with the air connection.
Re: Moving sand underwater, does anyone have pics of equipment being used?
Jason see that shiny thing going around the PVC pipe? Thats a hollow sleeve that allows the air to go all the way around the pipe. There are a series of small holes (1/4") around the PVC instead of one big hole.
Yes, I'm running 6" discharge hose.
