Question for you D2 users

[RgnFn]

I find myself flummuxed about my ability to pinpoint with the D2. On the Apex, after only a few hours, I was able to pinpoint so well that I rarely needed to use my pinpointer. But on the D2, I've been surprised a couple of times to find the target 4" away from my 6" plug. On the Apex, the target is exactly in the center of the coil when the tone is loudest, so I assumed that's where the D2 is pointing? Or is it to the front or back of the coil? [nitpicking gripe: the manual describes how to access the pinpointing function, but doesn't say anything about where on the coil the pinpoint is - pftth]. I ask this because when I tried the 13" coil for the one and only time, I noticed that tone (and visual) was strongest twice - once about mid-way to the front, and once again about midway to the rear (in both cases it was strongest in the center with respect to left and right) - but in the very center of the coil, it was reading as distant.

Thanks in advance for you advice.

Hmm.
Got a question for you. What reactivity do you generally run when you see this. I’ll bet slower(lower) vs faster (higher) .

Hmmm.... good question. Didn't occur to me that the pinpointer function would be affected by the other settings. I'm still learning the machine, so when I find something interesting I tend to bounce between the various stock programs to see how it sounds in each, and I'm afraid I don't know what program I might have been in when the phenomenon occurred. My guess is that it was set at 2.5 or 3. I'll need to note the reactivity next time I run into it. Thanks for the idea, tnss

I asked the question for good reason. Running detector slower. Like reactivity .5,1,1.5 and perhaps 2…..Some detecting scenarios the Deus 2 can alert tonally on a nonferrous target with masker (could be ferrous or nonferrous. Use of notch this can happen. And the target detected not directly where tone is being gotten (spot on ground). I have done few videos on this same topic. Showing Deus 2 and Manticore. Can even happen when using smaller coil like M8 coil on Manticore. Videos are available for your watching should you decide to watch.

I tend to use the wiggle back method way more often than the actual pinpoint mode. It has some advantages. It allows you to pinpoint with discrimination and is faster (IMHO) since no button presses are needed. When the audio goes away, the target is always about an inch in front of your coil.

But on the D2, I've been surprised a couple of times to find the target 4" away from my 6" plug.

The targets that have been offset, were they ferrous targets?

 

[RgnFn]

Thanks, tnss, I'll check your videos.
Thanks, rattlehead, I'll try that.
Beachhunt: they were non-ferrous.

So, I guess I'm still asking, is the target in the center of the coil (both horizontally and vertically) when the signal is strongest, or is it towards the front or back? On the Apex, it's dead center.

It is possible for nose or tail of coil (more so towards where better signal is achieved. Caused by masker. Could be ferrous or nonferrous. Nonferrous though use of notch could maybe cause more. Slower speeds (reactivity) cause the edge of coil to be stronger vs higher (faster speed settings.
Put another way. Running reactivity 3,4,5,,,your signal (target) achieved likely to me more close to dead center of coil when it sounds off. Slower speeds can yield more what we will call trailing signals.
Solo sitting no maskers you shouldn’t see this. Granted slower speeds you will have more coil latitude for actual detection on shallower and mid depth targets. Deeper signals likely to be more middle of the coil.

Example. Let’s say you had a 4” deep dime near an elevated sidewalk side. Sidewalk was elevated high like a foot above the ground.
So sweeping coil over such elevated sidewalk likely wouldn’t do any good. So you are forced to push coil up to edge of elevated sidewalk and sweep longways beside it. It you run Deus 2 faster = bad idea. Slower you have higher chance to either hear or get a stronger signal on the target. Now you may detect the dime very close to edge of sidewalk yet coil center is where? No where close to being over the the dime.

I also always use the wiggle back method because most of the time the target isn’t alone. Technically the target should be getting the best response in the mathematical center of the coil, round or oval like the 13”….IF the target is alone and sitting flat, such as a coin. Many times it can be different though, as described above.

That is a bit concerning. I would have suspected Ferrous.

With that said, your reactivity is plenty tight at 2-2.5. So why not X the target in discrimination and dig?

When I hunt the beach, I NEVER switch to Pinpoint mode.

You are welcome.
You see there are no dumb questions about detector use. I don’t prejudge anyone based on a question or difficulty they are experiencing. Instead and I try think and think about my experiences (applications). And then share data to help a person out.

Is all detecting scenarios swept by the ole sharpshooter, are the targets exhumed nice and easily? NOPE.
I suspect there will be times using Deus 2, no matter what you do, when you dig you miss the target. Unless you dig about a 10” wide hole. Then you likely won’t miss. Now, me saying this I am not advocating digging 10” wide holes. Especially in manicured lawns , public places like parks, etc.
Cheers.

D2, Manticore, Tarsacci, CTX303, V3i, etc...
Some folks love it though. Whatever rolls their stones.

I do some very small gold nugget prospecting and micro jewelry hunting with Deus 2. The hot spots on my Deus 2 9" coil are similar to what you described. Under the MF of the FMF label and near the coil ears gives me the strongest response on smaller targets. The 13X11" coil is similar with two hotspots like you described.

Pinpointing with the 13X11" coil is an adventure for sure. It took me more than one attempt to get the coil centered over targets using that function....more like a few dozen until I got used to it.

Like tnsharpshooter said, not everybody can dig big holes and some of us really need to use the Deus 2 pinpoint function to zero in on deeper targets that are beyond handheld pinpointer range when detecting on nice lawns and public turf areas. The 9" coil does okay. The 13X11............

 

[RgnFn]

Thanks everyone for your advice!

jmaclen, thanks for validating what I was seeing with the 13x11. At least I'm not totally crazy. Well, ok I guess that doesn't prove I'm not crazy, after all I fell for this hobby...

Obviously, I need to practice with it more....

Wow, stetam, that's EXACTLY how it seems to me on some days. Thanks for sharing the magic decoder!

Wiggle off pinpointing is the best way to miss your target entirely. The magnetic field is not a cylindrical shape, so the signal will terminate at different points depending on the depth of the target. Not to mention, the magnetic field 'curls' so depending on the shape and orientation of the target, the point of signal termination can vary greatly.

Also, on a Double-D coil, the magnetic field is most sensitive in the center only along the x-axis. y-axis (from nose to tail) can have two spots of greatest sensitivity depending on the exact geometry of the coil that are displaced from the very center.

Cross pinpointing is super fast and inarguably the most accurate method of pinpointing with a Double-D coil. When you get good at it, you don't necessarily even need to switch to pinpoint to achieve the same result. Every other technique is problematic and unreliable when precision matters.

I'm on the "wiggle back" method train. It seems to me if the target is trash the pinpointing is more difficult. Think the difficulty is produced the shape of the target more than anything else.

I use all three methods. There are good reasons to use them and not exclude one or two of them. I only use the pull back method on shallower targets.

Same here. Wiggle back works well for me on the medium to shallow stuff, especially in trashy areas.
I do like using the standard pinpoint mode making an X over the deeper targets. Just not a fan of the pinpoint mode on the D2 due to having to use multiple buttons to go in and out of the mode. Plus, XP needs to squash the pinpoint speaker volume bug in 2.0.
