A quick Catapult tip from Drennan Team England International Steve Hemingray:-

“Drennan Softfeed Groundbait catapults are great for a set distance, but if you want to feed Groundbait accurately say up to 30 metres, simply swap the Black Softfeed elastic for the Blue Medium-Strong Maggot catapult elastic, it fits perfectly & improves Groundbait accuracy at short range.” –  Steve Hemingray, May 2012
