Very easy to make with good sucking power. the black rubber is just a tie rod boot cover off a car and the pipe is 60mm.. You can use it like a izi to hold more material or without. I also have different nozzles and a bigger material mag. jimmy bedrock attached the following image(s):

The rubber boot was $15 from super cheap and the rest was stuff that I had at home. If you want to make 1 just give me a yell if you get stuck. The best part is no sand or grit will effect the suction unlike normal syringe types that need a tight seal. Edited by user Wednesday, 3 September 2014 7:04:03 PM(UTC) \| Reason: Not specified

I know all the water would slosh out there also rather than through the nozzel.

Keep it simple. Wet suit, mask, snorkle. Get right in to the water so you can really see what you are doing & just a simple crevice sucker pump & a crevice scraper & possibly a decent pry bar or slide hammer to smash open cracks & crevices.

I want to use it both ways or I would glue some of the joints...remember you need to get the gold back out of it lol I added some more pics and I keen to see other peoples versions if you make them.thanks

Was assuming Y joint fits into large open end but there is a smaller hole at the other end on the steering bellows I have looked at and I thought this would need to be sealed.
