Gee Dan, give away my tricks. It says right in the game regs, no larger opening then 4". That means feet right? Did you make a turkey trip this year? Email me if you did. I know how stubborn those old timers are. I have three I dig for because using those "guns" all those years crippled them up. Do you know how tired your are after digging for four people? But they have admitted I can pop the little buggers out good and fast. My disabled buddies just walk along behind me and pick up the clams. I look like a kite tail with all the disabled shellfish tags fling from my jacket.
