try doing a google search for ''Travel'' landing net handle, or as montainm says ''Stalker'', i think ''Fox'' used to make one, and he is right ''reach'' may be a problem if using from the bank, PLEASE NOTE:- when using too short a landing net it is all too easy to end up falling into the river through overreaching, it can be very dangerous on steep muddy banks, people have drowned on the fens drains when thay have fell in and not been able to scramble back up a very steep slippy bank.
Tried that search and found a 2m pole which folds up to 62cm which will just about be small enough. Not the longest reach I know but will be fine for where I go and it is only about £8
Can anyone suggest a landing net which has a decent sized net but that is the right size to fit in a small rucksack when the pole is collapsed/in pieces.
Cheers
