The rig must be used with a pop-up bait, as this will cause it to sit correctly as shown in the pictures below. You can get the most out of the 360 degree rig by making sure it sinks slowly, so it rests lightly on the bottom. The stiff mono line boom section allows the hook to fall away from the lead so it presents the bait well. I find this fishing rig works well when it lays nicely onto a soft silt bed, or lake onto a bed which has bits of debris and leaves. On these beds it wont look too much out of place. It could be used in weed, but I feel that the stiff boom may get tangled amongst, or in between, any weed stalks.
I would suggest using the 360 degree rig when the carp in your water are hard to catch!
