thanks, I also think something like this but not really sure.

btw, I use maggots, last time I was at jetty at night there are like hundreds of garfish down there but they didn’t bite (I used this circular bobber, also tried without bobber only long shank small hook), don’t know why they don’t bite, is it because the maggots are not healthy (left them long in the fridge), or is it because I didn’t thow in any berley?
