Double shovel post hole diggers are used to dig tight fence post holes. They are usually used in conjunction with a Fencers Graft. Tight, smaller holes mean you need less post-mix and generally, the less the ground around the post is disturbed the better.
Exercise caution when digging post holes, check for power cables and service pipes before starting to dig. Repairing fractured service pipes is expensive, but cutting into power cables is very dangerous and potentially life-threatening. Power cables, gas, water and sewage pipes have been found in places that you would not expect, even embedded in the concrete around an existing post. When digging fence post holes we advise using wooden or fibreglass handled double shovels and wearing rubber-soled shoes and rubber gloves.
