https://www.imscompany.com/ProductNavig ... ber=120743They have a Blue, see thru hose, in 2 inch for $2.20 a foot, BUT if you need 2.5 inch ID, the price almost doubles to $3.50 a foot.
The Kuriyama Tigerflex hose is made close to where I live , about 20 miles away. They sent me to a local dealer, Motion Industries,I think it is. If you can pick the hose up in person ,no freight charge,just local tax. Kuriyamas phone number is 847-755-0360. They have Tigerflex see thru hose model WH100 specificallys says for gold dredging, 45 psi.
Ps, Russ, we now have a placer on the Wabash river with easy access from a campground, and I have seen some pickers and rice grain chunks dredged out of it.The area covers about 200 feet wide of river by at least 1/2 mile long, but bottom is soccer ball size cemented cobbles and black water, VERY difficult not to trip. I need to wear a life jacket and will keep a large inner tube around my waist for safety. Built me a homemade 2 inch dredge with 5 foot long pvc pipe handle to the nozzle, so I can try dredging while standing up.
