pinpointing DD

[pulltab]

Got the Omega!!! But ive never used a DD coil, notice that under theTecnetics stcker seems to be the sweet spot.
but seems a litte harder when i cant see the coin.
Was just wondering if someone had easier explanation or maybe a link to a video .
I will keep practicing. I just dont want to spen all day trying to find a target if someone understand this better than me please speak up
Thnx Pulltab

I rarely use the pinpoint function. If you look at the depth bars you can determine the depth from that. Once I find a target I sweep the coil over the target while slowly moving it back toward me.
When I loose the signal, I move the coil forward until the signal reappears. I may do this several times to determine the exact location. The star on the coil diagram should be over the target.
Always make sure you have the strongest signal when doing this to make sure you are over the target and not off to the left and right. Hope this help.

I seldom use the pinpointing function either. Just sweep back and forth ,note the strongest point, then do the same thing from 90 degrees. I use a cane to put on the spot.I cut about a Three or four inch plug. If it is real shallow I can pick it up with the Garrett pro pointer. It usually is right where I have the cane. The cane really helps me both while pinpointing the coin and to help me get up. With out it, my right knee gives me trouble after about an hour of detecting. I am 71 years old. I have been detecting since the sixties. My first detector was a Whites Coinmaster four. I found forty three coins yesterday with my Omega and 11 inch coil. Also have the tiny little four and 3/4 inch coil. A very surprising little coil.

Okay, so maybe sometimes it can be a bit of a challenge at first, but the biggest three things to overcome are:

1.. The mental game some people play on themselves just "thinking" it is difficult.

2.. Understanding that coil SIZE can be more of an issue than simply the internal winding design.

3.. Understanding that ALL coils, both Concentric and Double-D (also called Wide-Scan), will 'pinpoint' a coin or similar target that is laying 'flat' to the coil in line with the center axis of the coil. On shallow targets i might seem like a coin can be isolated near the 'toe' or 'heal' of a DD coil, but as the target depth increases, this becomes less and less true to the point where the target is almost 'centered', quite similar to a Concentric coil.

All too often I work with people who have formed a mental picture that a Concentric coil projects or generates a 'V' shaped signal or electromagnetic field, an that a Double-D projects or generates some sort of a "wiper-blade" look all the way down from front-to-rear of the coil. Both of these often misquoted descriptions of the generated EMF are incorrect. What we need to be concerned with is the effective or reactive portion of the EMF. Then, to assist with pinpointing using a D-D coil, it might help to raise the coil a little off the ground (to work the target with the smaller working area of the EMF) or to reduce the Gain or Sensitivity, but especially to cross the target from two intersecting directions (roughly 90

Not just for getting along, and especially when trying to get up, but when working in sand or dirt and such to mark off the ground as you hunt to 'grid' the site.

"... then do the same thing from 180 degrees.

I think you mean from a right-angle which is 90

Like I have told people on here before its real simple find your target and pinpoint, the center of your DD coil on the Omega is were the black dot is on the top of the coil, now rotate your body and coil 90* wile the coil is still on the ground ,were the 2 points meet is the target LIKE X marks the spot. Lay a coin on the top of the ground and practice in 2 minutes you will have it, when you are out detecting when you dig a target don't dig huge hole, I dig a 3x4" hole only cutting out 3 sides that way the grass want die.

Got the Omega!!!

Great! However, you didn't mention which Double-D coil you are referring to, nor did you state WHY you are using a Double-D rather than the stock 10" Concentric coil. Personally, I am always curious.

sorry i was using the 11" coil the"deal" I got came with the 11" and the 5" round. The 10" will be here tomorrow. The white 5" works fine so I thought I would try the 11 to see how it pinpointed.

But ive never used a DD coil, notice that under theTecnetics stcker seems to be the sweet spot. but seems a litte harder when i cant see the coin.

Well, if the Teknetics decal "seems to be the sweet spot," then that sounds like the 5" DD coil. If so, it would be close to that. Essentially, dead center.
I was referring to the sticker on the heel of the 11


thank you all for your help. will try it again tonight

There is a small black dot on top of the 11" dd coil That is a decal. HH

Having the 3-coil set is great! If you don't have spare lower rods, I'd suggest them so that coil changes are very quick and easy afield.

I'd suggest you reduce the Sensitivity as you practice to learn pinpointing techniques, as well as working with the 11" coil about 3" or 4" away from the sample coin.

I was referring to the sticker on the heel of the 11.

As Cache Man and I stated, the most accurate pinpointing will be along the center axis of the coil (unless a target is odd-shaped or on an unfriendly angle) and with the 11" DD coil you'll see the small round 'dot' from he forming of the coil housing and that will be your reference point, and just use your imagination to picture a 'line' from front to rear with that 11" DD coil..

The 11" will take some people a little longer to acquire a good feel for pinpointing due to it's large size, and even the 10" Concentric is a little bit of a challenge for some due to the elliptical shape. Honestly, mastering PP methods with all three coils is quite easy.

Best of all, get out and use that Omega and all three coils to determine which coil will best suit you and your hunting needs.
