Whistle top type, also operates by a ball valve but has a fitting to attach extention rods in the top which then requires a side opening (that resembles a train whistle) to empty it.
It is superior in muddy materials or clay lenses because the sludger can be pushed down.
Can also be used with rope by ordering a rope loop.
