Anyone else having trouble pinpointing?

[jimmyk]

Hi, all:

I've had my F-75 for nearly a month and love the many options and the way it performs. I've had none of the problems (knock on wood) others have been having. I AM having trouble pinpoint with it. I'm an experienced detectorist and have used most of the brands of detectors over the years. I've been clad hunting to get used to the F75 because the ground is VERY dry and I don't want to yard hunt and kill someones grass by digging a plug. I've been hunting a school field used by the High School band to practice their presentations for football games. I've dug several hundred coins there this month. Deepest has been three inches. Anyway, I pinpoint by detuning the detector over the signal until it gets down to about three inches square area. When I dig, about everyt fourth hole I have to enlage to find the coin. I start with a six inch plug, and when I have to enlarge the hole it can get close to a foot in diameter. I think it may be coins that aren't laying flat, but I find it hard to consistantly pinpoint a target. I hope Sunray comes out with an inline probe soon. If they don't, I may break down and buy one of those pricey Uniprobe units. I need a probe with some depth in it to help locate targets in the ground. Anyway, just curious if it's just me, or if others are struggling with it, as well. Outside of tha, I really am sold on the F-75. I'll be glad when we get some rain and I can hunt some yards for older and deeper coins.

keep on diggin'

Jimmy, I have had the F75 for about 3 months now and still have troubles pinpointing with it. Seems the deeper the target the better the machine PPs. Its the surface stuff that throws me. I have tried lifting the coil, using the toe and heel and still ain;t any better at it. Hopefully that small coil will be out soon and it will help narrow down the PP ability. It may just be all this dry ground too. Seems to be raising cane with everyone right now, not just F75 users. My hunting buddy can PP the eyes off a worm and he's even complaining about the dry soil.

I was having some trouble too and was used to the sun ray on my explorers. Finally broke down and bought a pocket Uni. It works great and the extra 2-3 inches in depth is nice also.

Yes, I have trouble pin-pointing, also. The pin-point area is large, even after re-tunung.

I'm a newbie to the F75 by three months and agree pinpointing can be a challenge - however I offer a suggestion given to me. Shallow hits are a problem so when I note a shallow hit, I try to center my coil over the signal source and then holding the pinpoint trigger - I draw the coil backwards towards me and note when the signal ceases. I then assume the target is under the forward point of the coil. Since this tip was passed onto me recently and having limited hunting due to dry ground - all I can say is - its worth a try.

The All Metal Sensitivity setting affects the Pinpoint sensitivity. Switch over to the All metal side and turn the all metal sensitivity down. Or up it you need to. Remember that once you go below a setting of 30 it will act up on the all metal side but it won't act like that when pinpointing.

Also, when you detune on the target, detune right over the target until you can't hear it any more. Detune over it twice if you need to. Then press your coil to the ground over the target and you'll pick it back up, but only in the very center of the coil. You can pinpoint fast and probe targets quickly and easy this way in turf.

I'm only using my Uniprobe when I'm plugging deep targets.

Another thing.....since shallow targets depth reading can be off when pinpointing, learn to rely on the depth bar and the audio sound of the pinpoint to give a more accurate depth on the shallower targets. Once you get past the 5" mark the depth readings are more accurate.
