I'd want both eventually, but I'd go with the pinpointer first.
Like some say, it can all be done with the detector alone,
but I think once you use a pinpointer a while, you will be
spoiled.
Myself, I use the pinpointer on most every hole, and I'm good at
pinpointing with the machine alone.
I'll pinpoint an object, and then erupt the dirt up over the object
with my probe, and then I stick the pinpointer probe down
in the hole. Most of the time, I pick up the coin on the first
try. But sometimes it's a little deeper, or maybe a bit back,
or on one side wall of the hole, or the other, etc,
so having the pinpointer tends to speed up finding where
it is for me. I don't usually pass handfuls of dirt over the 250
coil. I'll grab a handful, and then pass my pinpointer probe
over it. I can do the same while the dirt is in piles on the ground.
I do sometimes re-pinpoint using the machine though if the
target seems to have shifted. Also with real tiny objects,
having the pinpointer makes it easier to find them in the
dirt. My automax will detect tiny shavings of metal as small
as a ant. Maybe smaller.. The thing is really sensitive..
Trying to sift through dirt and then passing over a coil would
take longer for me.. Often the part is dirty and hard to see.
Anyway, that's my 29 cents worth.. I'm pinpointer spoiled,
probably cuz I've used one since day one...
But I'd consider the sniper coil next after that.. I consider that coil
a "must have" for any serious user of a ace 150/250..
Not that the objects couldn't be found using the stock coil,
but when you see how much easier it is to weed through
trash, and ID and pinpoint close together objects, you'll see what
I mean.
