Also, the smaller the hole, the less damage. So fer sure
worth getting down. On my particular ace 250, on the shallow
to medium depth coins, I place the "smiley" just on the outside
of the inner coil. "front" On the real shallow coins, it possible for
the dropoff to be a bit farther forward. But I dig starting
at the point just on the outside of the inner coil, and go
from there. About half the time, I feel the coin or whatever
when I probe down with my coin probe. It's the real deep coins
where you might see it fall farther back from my normal starting
place. But even then, it's often not that drastic, so I wouldn't
overdo it on the "to the rear on deep coins" rule. The vast majority
of the coins you will see won't be deep enough to see that to a
large extent. I would get/make a coin probe. Not only is it handy
for probing the objects, but I also use it to pluck or dig the
coin out. It does less damage than using a digger in my case.
I've dug about 500 holes in my yard since I got mine, and you
can't see hardly any of them. Only the first two holes I dug
using a digger ended up being noticable, and thats mainly cuz
I ended up with low spots.. My probe plucked coins, you don't
notice once it's rained a bit, and gets the soil back together.
I included a pix of my usual coin probes. One a pushrod, which
worked pretty well, and on the right my new fangled version I
made from a home depot phillips screwdriver. I ground down, and
polished the end to do minimal coin damage. It's 8 inches.
I actually wanted a 10-12 inch version too, but they didn't
have that length. They did have a real long one... I guess I
could trim it down for a "deep coin" probe... I have a stiff
one piece car antenna that I use for a "deep" probe. It's pretty
easy to get in and out and makes no damage at all as long as no
rocks..Just a tiny vertical hole maybe big enough for an ant mine
shaft... If anything will give tecter heads a bad name, it's
leaving nasty dug holes that take forever to mend, or leave bad low
spots that never do unless plumped up a bit with some soil.
Some dig holes and just leave em,

but I doubt that happens
with this bunch.

BTW, just as a last thought note...The sniper coils *do* pinpoint
in the center, but they are different animals from the stock 6.5x9,
or 9x12 coils..Both of the larger coils pinpoint on the outer edge
of the inner coils. BTW, you don't "have" to pinpoint from the front,
you can do it from the back too if you had to... Works the same
being it's a symetrical coil. But I do it on the front like most
people...
