Why is pinpoint mode (true all metal) better?

[Pinpoint]

I'm mainly reffering to the Excalibur 2 and SE, expecially the Excalibur 2. By better I mean better than in disc mode, and what is the technical reason for that?

The interpretation is in general simple. As you can not be the fastest and toughest man in the world at once, you can be only compromise between these two extremes.

Thus, even in electronics you can not maximize everything you wish, but still get some compromise. In order to maximize a single feature (eg. pinpoint), you must usually give up other features and vice versa.

In other words, discrimination does not improve the sensitivity of the device, but it worsens. But improves its ability to distinction between metals. Therefore, the device is in the pinpoint mode by rule more sensitive.

Define "better".
Do you mean "deeper"?

By better I mean better all round, exept for tonal discrimination. I think all metal modes will even have better discrim in general (except in high junk areas) because you can hear what type/shape/size the target is. AM mode will be deeper, more sensitive, handle mineralisation better, etc. You could still have discrim in AM mode, just look at the FBS minelabs and the like.

I don't understand why vlf detectors can't be designed with improved AM modes?! Is it too much trouble? I like what the whites BHID did, they simply put three LED's that still indicate in AM. I wish my Excalibur 2 had that, anyone know how that could be done?

Thanks, you explained that well. I feel that the compromise is too great.
