How to pump sand shrimp/ghost shrimp. Fishing Tillamook Bay

We are on spring break, so one of the trips we took was to the coast to do some fishing. Sand shrimp can be really expensive if you like to fish them in the bays or for salmon, steelhead, or sturgeon so when we can we try to get our own. Here's a video of how we generally pump them and rig them for fishing in the bay. We got showed up big time by another guy and his son, it was pretty funny. You can make your own gun out of PVC or you can generally buy one for around $20. Mine was home made. Hope you enjoy!
