Looking at a waterfall target.
Standardish kill, and 3ft in front of it arranged that you have to shoot through it ,is a waterfall, about 12ins wide, arranged to fall in a sheet in front of target.
Problem is to maintain a constant flow throughout comp.3hrs+.
Probably pump run on batteries as mains is a bit dodgy,with water about.
We have a rising rabbit at Lea Valley also,when tripped you have about 8 seconds from rising to falling under cover,if the kill is hit it is signalled that it is a kill,a plate is obvious and a miss gets lots of abuse.
