I use something similar here in NZ for our Snapper (your Sea Bream). I use 2 bullet shaped tungsten weights rigged with the flat sides touching each other. The tunsten weights will actually touch each other and make a clicking noise. This rig has caught fish when otner good producing rigs fail. Have also used Teardrop shape lead sinkers with a hard plastic button between them as this will also click and is a lot cheaper than the Tungsten rig. Our Snapper like the Orange tails over most other colours. I use 40-80 gram lead weights. The only Tunsten ones Ive used were 30gram.
@@angler-anchor Sound definately attracts certain fish. Have tried a small stainless steel washer between the weights too. Caught fish using it. Only stuck with the plastic because they can be bought in so many different colours. Have started using a piece of Red plastic tubing about 50mm long off electrical wire/cable ahead of the first sinker and it caught fish all day until we left to go home.
