I recommend using the sand crabs with the soft shells, that’s how I had the most luck. You could also try throwing a lucky craft jerk bait, those work well for nice halibut.
Trust me when I tell you this…..bigger is not better when using sand crabs. The ideal size is no bigger than your pinky or ring finger nail, with size 4 or 6 circle hook, snelled.Set up a high/low rig and they will set the hook themselves.
