What is your understanding of the "sizing" pinpoint mode on the E-TRAC ?

[jbow]

The manual says that normal pinpoint mode will reset as you swing, this makes the target pinpoint smaller as you swing. I have been using this and have found it to be very exact. I can put my finger right on a coin, if it's not too deep. I don't know about deep ones yet.

Sizing is what I am not sure about. I don't understand what ML is saying in the manual. It says: "When sweeping over the target the detector produces a linear tone. The pitch of the tone is proportional to the strength of the target response, and the volume is proportional to the position of the target under the coil.
Activating (sizing) pinpoint while the coil is away from the target will allow the extent of the target to be determined.
Activating (sizing) pinpoint while the coil is near the target will allow portions of the target to be masked."


1: Is a linear tone different from the tone in normal pinpoint mode?

2: I assume that by strength of the target they mean the depth and size of the target.

3: Determining the extent of the target is self explanitory but wouldn't normal pinpoint do that too? What is the difference?

4: "portions of the target to be masked..." What does this mean and what are the applications?

Have you tried sizing? I have always raised the coil to id aluminum cans and other large trash. Do you think sizing is accurate enough to tell a large coin from a smaller one or do the targets have to be more different in size?

Thanks,

Julien

I assume they just mean, make sure you move the coil off the target, then hit pinpoint and move back over it, it will give you full extent(size) of the target.. in the vco(normal) mode, almost everything will work itself to a small point.. everything will seem small..
The signal tone will increase in proportion to the target size and volume gets louder as you get close to center in sizing, but not sure they are saying if you want to mask portions, just warning you if you do I think

With the Etrac it seems to me the center of the coil is hotter than it was on the other machines but It might just be the pro coil as I have no trouble pinpointing in disc on the etrac with the other coils I used, and noticed on the SE with the pro coil I was usually in front of where I should have been digging after the target disappeared off the front, or what I assumed was the front


The old explorer XS and II motion pinpoint was great for telling size and for hearing multiple targets, not sure why they didn't put that as one of the pinpoint modes on the etrac...
they took it away in the SE as well... its one of the things I didnt like them changing on the SE... anyway its easier just to pinpoint in disc mode anyway for me.. I just liked the old explorer XS and II mode for telling if you had multiple targets close by on the iffier signals, and it was good for sizing, the sizing mode on the etrac is similar, but the old mode was just a single blip at the same tone that stayed on till you got off the target

It helps narrow down the target, however not good to use if you are relic hunting or trying to determine the size of something. Also if your first swing is over a soda can and you continue to size it down, you can be fooled by the size thinking it is a coin based on it's audio/numbers.
