Myself I feel too many are using shovels in these area. even the photos of many show using a shovel like the Sampson they cut a bigger plug than needed. I use a Lesche and a narrow tip screwdriver to pop out the ones no very deep.
I see one guy (dealer) that cut a 15 inch plug as he was using a 15 inch WOT so he would get the target, he missed it though as there was a seated dime to the side of the hole my fiend found.
I have 2 Sampson shovels that are only used in farm fields and construction site where neatness isnt required.
