I got in the creek with a Backpack dredge and soon realized that my arms aren't long enough to get down past the sand to the clay layer. I will need a hookah pump on my dredge. Looks like I need another gas motor and a gast pca-10 pump. These pumps are hard to find used. New they run around 680.00-700.00. That's more than I have into my Keene backpack dredge from the 80's with 2 stroke motor.
