Call before you dig
811 is the free national before-you-dig service. Anyone who plans to dig should contact 811 or go to their state 811 center’s website before digging to request that the approximate location of buried utilities be marked with paint or flags so that you don’t unintentionally dig into an underground utility line.

Chris Cook –
Nice heavy auger. the spiral is fully welded (uncommon these days) and the point has a fishtail auger (great for starting the hole). Works well on my Danuser phd. Only negative, it was shipped with no wrapping so the paint had a few chips (not a big deal considering it went straight into the ground but still).
