A play on words!!
These feeders make accurate long casts a doddle, hence the name! Side loading, you can fill these with particles, casters, worms etc, and just 'cap off' with a little groundbait. Therefore large quantities of loose feed can be introduced with a minimum of cereal. Water pressure through the holes and caps pushes the feed out, as the feeder sinks and soon as the feeder is retrieved.
Ideal for long range bream fishing on those big Irish loughs!
