Tackle

Rod & Line: 4 or 5wt floating line.
Bring a net. I advise on using a knotless net with a scale in the handle (McLean for example)
good wading trousers and Jacket
Headlamps are essential from on mid July
Flip Focals come in handy
Use strong leader material – Stroft 0,14 to 0,18 is best.
Strong hooks
