It just helps keep the fleas alive longer cause finding them at times can be difficult. I just use a small baby bubbler cost around $5. 1 or 2 AA bat. last 20 hrs. Gulf Rig doesn't have floats or hooks compared to the Pompano rig. Strong circle hooks baited with the fleas have been the trick.My wife and I caught 6 Reds this morning in the surf all in about 30 min. time.
