Plastic Quiver Rod Rest // Cathedral Baits and Tackle // Fishing Tackle Shop // Ramsgate, Kent
this is the type I use - bought 2 for £5 from a market stall
This is similar to the ones that I use but mine are that old now that the names have long since rubbed-off.
I prefer these particularly on commercial venues where the bites can be quite savage and the sliding mechanism gives you a second or so longer to react.
