Do not use swingers or hangers for indication of a run, as they will cause the eel to drop the bait when the line pulls out of the clip. My personal favorite is a bright yellow bottle top hung gently on the line between the butt ring and reel. When the fish takes line, the bottle top falls off, giving the eel resistance free line to take with an open bail arm. I think Lemon Sqeazy bottle tops are the best eel bobbins ever, and members of the British Eel Anglers Club and National Anguilla Club can't be wrong. Wire traces should be used for all eel fishing regardless of whether you are using deadbaits or worms.
All eels have teeth and can make short work of nylon and braid.
Quicksilver is also to be avoided especially if there are pike in the water, as they will make short work of this. Hooks are a personal choice, though I don't think you can go wrong with the Drennan Super Specialist, or the Jack Hilton Carp hook from Partridge, as they are both strong, and remain sharp for ages. Rigs should be un-complicated and allow the taking of line with out any resistance being felt by the fish. The lead should be attached to the main line using a weak link, so should it become snagged it will break before the main line does. Dead baits can be used whole of half, preferring the head half myself due to the fish oils and juices being able to escape freely.
