Deal with fishing gear (6)
I believe the answer is:
tackle
This clue is a double definition.
'deal with' is the first definition.
(I've seen this before)
'fishing gear' is the second definition.
('tackle' can be a synonym of 'fishing gear')
(Other definitions for tackle that I've seen before include "Confront" , "Take on; rigging" , "Rugby challenge" , "Undertake" , "Try to deal with fishing gear" .)
