Cache hunting Question

[landman]

Looking at Cache hunting again. Minelabs are out, don't like the sound of them in all metal. The PI's are IN but they are limited to the information they give and can detect deep but no nonmotion feature usually. Since you sometimes have to dig everything anyway no biggy. However sometimes you like to have some control in what comes through the headphones. The GTI is deep, has filters and imaging but in pin point I think is the only "nonmotion" all metal, but if I'm correct you still have to have some motion?. However the CX Plus has true all metal NON MOTION mode. Seems to look into the ground, the non motion all metal would be an advantage when determining size /signature a target gives. Any thoughts on true all metal non motion and cache hunting?

Or anyone can chime in. Any user of the CX plus?

I use a CXIII , which also has the true "Non Motion".

It seems to get real deep with this mode, although I have not used this mode much. I do plan on returning to an old root cellar this week that was productive, giving up some large cents , but I used motion mode.

I will throw on the 12.5" coil and give it a try there when I retun sometime this week or next weekend.

Thanks for responding Neil. I've discovered that there is a difference between all metal motion and all metal non motion modes. And when I mean "non motion" I mean that the signal sounds under the coil as long as the battery has life if you were not to move the coil.

If I'm not mistaken the GTI2500 touts all metal nonmotion? Well my experience has been that some sort of limiter quiets down the machine if you don't keep the coil moving over the metal object. If that's the case, then the CX3 or the CX Plus are the only true all metal non motion machines that garrett makes and maybe the only one currently on the market.

That being said I wonder if there are any advantages in determining targets size, depth when relic or cache hunting.

Yeah the 2500 requires at least a slight motion but on a motion detector this is what is required to get more depth and make for better discrimination when in that mode. Motion detectors go deeper and discriminate better the faster you sweep the coil.

IF you hit an iffy signal ( and the target is really a good one )with a motion detector all you have to do is whip the coil rapidly over the target to turn it into a good signal.

Bill that may be true but lets discuss the advantages of all metal non motion if there are any? Especially for r cache hunting where you will be hunting in all metal anyway. Anyones thoughts please.

I use the AM non motion in areas without lots of trash. I have the CXIII and found that I can get a better picture of what lies below by:

AM non motion
VCO to help determine size and depth
manual ground balance to area

This is good for relics and cache hunting.
I use a slower sweep when in this mode.

How does AM differ in determining this characteristics from the VCO. I've heard both sounds so I understand there is a difference in sound but what are your thoughts on the difference when using them together to see beneath the soil?

When using the VCO in AM mode OR motion mode, when you find small or deep targets the sound level will increase, for larger and targets closer to the surface both the sound level and the tone will increase.

I hope this helps...

 

[landman]

Almost it does and thanks. Now how does VCO differ in the characteristics of the sound inflection or shape if that's a better word to use? then regular all metal. Is the difference is that all metal does not change its pitch? Does this really help you think, VCO's pitch plus soind level? No one seems to either care or have an application for this, meaning no one talks about this feature.

I like the VCO feature and use it as my default. I do not think there is a difference in either NON-MOTION ALL METAL or DISCRIMINATE (MOTION) mode. I especially like it when pinpointing a very small target like jewelry or small buttons. It really helps to "zero in" on those targets. I find it is also helpful on those dissapearing signals at the edge of the detection range in MOTION mode.
