Seamed to do a good job keeping accurate depth of 3' digging a hole with my front hoe attachment.
However, when I put it on my bucket to cut some grade it jumped around lot with variance of 6"
The area was already pretty level, just wanted to try it out.
I will try again on my grading attachment next and see how that works.
