at the low water line ,you have to go walking till you find some ,walk backwards and you,ll see the squirt as the razor goes down in his burrow pour salt down the hole and he should pop up after a few minutes, if the wind is blowing in the wrong direction it will push the water too far up the beach to make it worth your while going so check the forcast first

a 0.03 or 0.02 tide should produce a good crop
