Do mesh bait bags ACTUALLY work? Sheepshead and Black Drum bait

I have seen several people that swear by these mesh bait bags for catching Sheepshead and Black Drum. I don't believe anything I hear and only half of what I read. I had to try this for myself to see if it was the best thing going. I have another pack in the freezer and will re-test this theory sometime soon.

16' Sundance Skiff, 30HP Mercury

Shimano Torium 20HG - Shimano Trevala Jigging Rod 6'6" Heavy, Medium Fast
Shimano Stradic 4000 - Fenwick HMG 7', Medium Fast

100 Pound Power Pro, 80 Pound Fluorocarbon Leader

Catch Mud Crabs under "stuff", below the high tide line (WEAR GLOVES, oyster cuts are nasty). The purple crabs with spots and striped legs are stone crabs and are illegal to possess.

Catch Sea Urchins on pilings and other structure below the high tide line (WEAR GLOVES, the spines are non-venomous but can leave splinters and oyster cuts are nasty), I recommend using a crab net.
