Yep some were down at 2ft (sorry forgot to put details in first post!)
Using a C scope CS4PI, at "3 o clock settings" balls ranged from 6" down to 2 ft, nasty wet cement like sand. Dig tip, create a dam of sand around the hole to stop surface water ingress, makes life much easier when you can do it.
Lol at Fred - I am just recovering from a hernia (maybe it was digging on the beach!) and I now have 46 balls here in my stash! Just need to wait 2-3 years whilst they soak
