Well; I would be lost without my FLYCATCHER brand staff and have used it for many many years. It is solid aluminum, about 44 inches and has another tube inside that can be extended to near double the total length. On top there is a "hook" that collapses that can be used to HAUL down branches to retrieve your your fly.
Like so many others I have it on paracord hitched to my waders strap AND let it dangle in the current though I sometimes get my line tangled upon it.
WHY? I crushed my fight foot/ankle back in 86 and the ****ed thing has been fused three times so I have no lateral motion OR BALANCE AT ALL on that leg. Most useful in the Sevierville freestone stuff, Below Cherokee especially Nances where there is lots of Cobble... on the Clinch it depends on the bottom.
Oddly I still manage to take some very serious diggers every year... can anyone recommend ELBOW PADS?
