spots get hammered so nippers would probably be deep on low tide. look for dark sand patches with a hole/mound in the middle, yes in the water.you can definitely get them at seacliff, this is a well known spot, go there and look for people with pumps ;)also because they get hammered, people do not like to freely give away spots. I've only ever got them at the o'sullies boat ramp, but they're not there anymore.
