Equipment with long cord bound to catch fish (8,4)
I believe the answer is:
skipping rope
'equipment with long cord' is the definition.
(a long rope)
'bound to catch fish' is the wordplay.
I cannot quite see how this works, but
'bound' could be 'skip' (I've seen this before) and 'skip' is present in the answer.
'catch' could be 'grope' (both can mean to search around) and 'grope' is present in the answer.
The remaining letters 'pin' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for skipping rope that I've seen before include "toy" , "Cord with handles for jumping over" , "Training aid" , "Item avoided during play" , "equipment used when jumping" .)
