Show at Erskine displaying leisure equipment (5,3)
I believe the answer is:
water ski
'leisure equipment' is the definition.
'show at erskine displaying' is the wordplay.
'displaying' indicates the answer is hidden within the clue.
'WATER-SKI' is hidden in the letters of 'show at erskine'.
(Other definitions for water ski that I've seen before include "Aquaplane as a sport" , "slide over lake, say?" .)
