Pinpointing--What I've Learned

[jjwest]

Decided to make this a seperate post as some really good pinpointing info was being put into the high density post.

Just my 2 cents on what I've learned from others here and in the field. I've stopped using the pinpointing mode on the Quattro about a year ago. I just use the toe to pinpoint. Put the meat of the coil over the target and pull the coil to you while swinging it slowly. When your numbers and sound start to change the target is under the toe of the coil. Rotate 90 degrees and repeat. Now you know where the target is. Sometimes for a cleaner break of a good signal to one that is not, lift the coil 1" to 2" off the ground when pinpointing. I believe Golden, mentioned this over a year ago. It works.

Sometimes when the ground looks the same in an area or in a park with grass I put a golf T in the ground before rotating 90 degrees to help remember the location of the target.

Most of the time I just coin hunt and something that has helped before pinpointing is to guess the size of the the target with the toe and heel of the coil. Find the near side of the target with the toe that I mentioned previously for pinpointing and then move the coil back over the target and away from you swinging slowly. When the sound and numbers start to change the heel of the coil is at the far edge of the target. Now you can guess if this is worth digging. This has saved me a lot of digging as I don't know of any regular coins that are 2" or 3" in diameter.

hey jjwest, ive done that b4 also w/ the swingin the coil around it 2 see how big the target is. i figured that out awhile ago, saves some diggin time. but w/ my luck itll be a crap load of coins in 1 spot or a metal box w/ coins and a diary in it n ill pass rite over it cuz its size is big lol. oh well. also id love 2 have me a 2 box detector BUT id also have 2 get a back hoe w/ that, who wants 2 dig beyond 10 -12 inches w/ a little shovel. hey honey good and bad news. good news is i found the biggest cache ever of valuables, bad news is its 20 feet down on property that aint even mine. who cares get the screwdriver out. yeah rite lol

That's a good post. Your right, as far as I'm concerned. You can literally "feel" the length of the target by the sound and the visual most of the timie. I don't ususally go for the "toe" thing, but it can certainly be done, and now that I think of it, that's a pretty accurate way to find where the target is in one direction and then turn 45 degrees and see where it is in the other direction to draw an imaginary x or put a golf tee there. Good stuff. Marc.

A great tool to have on the Quattro is a Sun Ray inline probe for pinpointing when you are down on the ground and need to cut a plug out. It can find a coin at 3". This really helps out locating the coin. What I do initially with the probe is wave it over the golf tee(location of target initially found with Quattro coil). If I hear the target then I know it is within 3" of the surface of the ground. If no sound then it is over 3" deep. This kinda confirms what the Quattro indicated the target depth to be.

I try to cut about 2" diameter plug when on grass lawns or parks down to 4" and usually the coin is within the plug. A couple of times I have been unable to find the coin within the plug. Where is the coin? The coin has to be on the side of the hole and the Sun Ray probe is too powerful for tell the exact location on the wall. Then it is time to pull out the old White's Bullseye hand probe(glad I didn't sell it) which is only good to about 1/2" to 3/4" on coins. This will find the coin on the side of the hole without making the plug diameter any bigger. One thing I need to try, is to decrease the Quattro sensitivity that I normally run at 18 down to 12. This should make the Sun Ray probe less powerful and better at locating coins on the wall of the hole and the Quattro should still find coins down to a good depth. Yes, I know that cutting a bigger diameter plug would help.

The Sun Ray probe is pricy(about $215) and adds a little weight(just think of it as healthy exercise) to the Quattro but I would buy it again. The reason I purchased the Sun Ray probe is because I have an artificial hip and once I am down on the ground I want to stay down on the ground till the target is found and not getting back up to relocate the target with the Quattro.
