Question for XTerra 705 users

[chuckciao]

I am using the Ace 250 and although I like it in general, I am having difficulty differentiating trash targets (mostly metal twist caps) from dimes. They seem to give off the exact same signal and show up on the scale as dimes. I seem to dig 10 of these for every dime I find. Discriminating does not help since I will lose real dimes if I notch it out. Am considering buying the X Terra 705. Does it do a better job of eliminating these trash items? Thanks

I think so.. I can basically tell a pull tab from a dime no problem with the 705. My wife had sort of the same problem with her Ace250 also. She is now using my (hers lol) xterra 30 and is able to better discriminate. Em

Thanks for the info. on the 705. It seems like a great machine.

The number of notch segments available on any given detector help determine the ability to separate trash from treasure. The Ace 250 that you are using lumps each target into one of 12 catagories (notches). The 705 offers 28 notch segments for these same targets, thus more than doubling the number of catagories where a target might be catagorized. Add to that the additional functionality of the X705 (adjustible GB, Auto Noise Cancel, 30 segment adjustible Sensitivity, adjustible Threshold, 28 multiple tone audio, three operating frequency option via coils) and you can see how fine tuning the X-TERRA will help eliminate some of those targets that are fooling you now. However, I will admit that screw caps are difficult to identify with any detector. I have several "high end" detectors, including an E-TRAC which offers both ferrous and non-ferrous target property ID, and they all get fooled once in awhile. But getting a detector that is capable of separating targets via a greater number of notches is bound to increase your treasure vs trash ratio. JMHO HH Randy

Randy,
Thanks for your excellent and comprehensive run down of the X705. The way I see it, with my Ace, I am going to continue to
be plagued by those pesky screw tops with very little I can do about it but with the X705, I have more tweaks and options at my disposal.
Thanks again,
Chuckciao

I usually always know when I have sa screw cap under the coil. It gives a solid 32 almost everytime. I do dig all 32 tids though as I have found some coins that read that on occasion. I have a 70 and they TID the same.

Indeed - screw caps = TID 32 which here in Australia happens to be the same TID for a $1 coin! Some 705 users here in Oz says that they can hear the slight difference in sound between a $1 coin and a screw cap. I have yet to fine tune my ears

Cheers

that the Ace can actually do a pretty good job of IDing screw caps. The secret is to listen to the pinpoint audio fade. What you do, is go into pinpoint, then go over the target, then pull the coil back towards yourself. As the 12 o'clock position of the inner coil you will hear the audio signal fade. A coin will fade pretty quickly, while a screw cap will have a distinctly longer fade. The only caveats to that, is if the target is within 2 inches of the coil, or you pass over a second target as you draw the coil back In that case, the pinpoint won't break off till the last target has peen passed over. That doesn't happen that often. It becomes a 50 50 call. It's a lot better than a 10 to 1 call that you are now experiencing. It does take a bit of practice, but it's fairly good.
The X-terra 705 has it's own little tricks. I have the X-Terra 70, so I don';t have the sizing pinpoint feature, that may offer up extra target info. However, the first trick that you come across is the VCO pinpoint. This is most helpful on targets that are up to 3 or 4 inches. A screw cap will scream noticeably harder than a coin. Another thing you you can do that are a bit more subtle, is to pinpoint using the prospecting mode. If you can establish a slow to modest sweep speed while in this mode ( make sure you maintain an even same speed each time you check a target) then you can hear the difference in the width of these 2 types of targets. I'm not a 100% sure of the size of your dimes, but I think that their size is noticeably smaller than screw caps. This is what makes it easier to tell them apart.

Excellent Advice Mick. I will try this trick the next time I go out.
