Took the Sand Shark, CZ6a and CZ20. Hunted with Sand Shark on Saturday and CZ6a on Sunday. Didn't get the CZ20 wet on this trip. Spent most of the time in the wet sand. A lot of the bottle caps found with the CZ6a came in solid mid-tone tab. Bottle caps usually hit high tone and then flip high to low tone when I swing real slow over them; not this trip. $4.36 in change, a shark car and assorted junk. Great to be out getting covered in salt spray!
