looking for a clam tube (for gaper/horse necks)!

Oregon and Washington laws different of that in California. might be considered wanton waste in the state of California

Yes, it would also be considered waste here in Oregon as well, and I hope I didn't give the impression that is the avenue I take with pittocks. 
I have only attempted to dig pittocks this one time with only successfully extracting one clam after a long battle of chipping away at the base substrate.
Gave up on that area until I can get in there with a longer handled trenching shovel.

Definitely easier clams to out there it target.  Those pittocks are evil!   

I'm with sand shred, all you need is trenching shovel. So easy and a lot faster   No more back breaking aa d doing the dance on top of the tube to get it deeper

It all really depends on the substrate and how deep the clam is. At least in my area (NorCal) black silty stuff with razors digs fast. Deep course intertidal sand is like quicksand and even with 2 guys digging fast you can't get more than 1-2 feet deep without walls caving in. Hence the need for a wide deep tube to fit a shovel and move down around the clam - which can be 3-4 feet deep if we're looking for gapers/horse neck.

this ones work too at Lawson's landing
