I love it!
I use a simple 2-4oz weight on the bottom of a crappie spreader rig, with berkly gulp sandworms in red and camo.
Really helpful to scout good areas of structure at low tide for the perch. I try to fish the 3 hours leading to high tide, and the first hour of the outgoing. Seems to be slower the rest of the time.
Got some sand weights at bobs last trip i really like. Thry are a holloe triangle with little nubs to help dig in. They work awesome.
