XT-70's VDI disc. segments?

[David]

On its VDI, the XT-70 has 28 segments in steps of 2 from -8 to 48 , (4 ferrous and 24 non-ferrous).

Even the $199 Fisher F2 has 00 to 99. The MXT has more VDI numbers.

My question is, would more VDI numbers make the XT-70 a much more accurate-surgical discriminator or not, would this improve the XT-70 and is this lacking ??

Thanks!

It's a fact that the more segments or numbers the more jumpy your TID will be. Your TID is another tool to use. But it should be secondary to your beep. Now if your just cherry picking then you would rely on the TID more.

48 non-ferrous numbers with 24 target segments is sufficient IMO. Personally I'm not a fan of notching.

As to whether more VDI numbers would do what you are asking, only the engineers can answer that. The X70's software is written to work with the target ID as is and it does do a good job. The engineers have set goals in mind when laying out a new detector and design everything around those goals.

I think most all current offerings are pretty good at locking on "in the clear" targets with solid ID's. It's when you have co-located targets where ID accuracy can be tough to attain. In that case more target ID numbers can only help if the underlying software is up to the task.

Personally, I find that the extra numbers on my XLT don't really help. I prefer the smaller number of segments. I don't think that you will get much better results than you will with the 70. The highest resolution of numbers that I've seen work, were on the Quattro at 40. The E-Trac at 50 may well work accurately from what I found playing around with one in a shop, but anymore would seem to result in no greater clarity.
I find that the numbers are only about half of the information that helps you. You will find over time, if you have a good quality detector in your hands, once you have spent time with it, you can really start to tell what a target is, by using a mix of techniques that you pick up. Till the day comes when real time accurate ground imaging arrives, then the ' ART' of detecting will be alive and well. After all, isn't that part of the fun.

I use two tones and just dig all non ferrous tones. I don't pay a lot of attention to numbers. Remember this, if you place too much TRUST in those numbers, you will leave a lot of good stuff in the ground assuming it is trash, if you dig it up, you get all the goodies

if you have 2 targets close together one trash and one good, the VDI will combine together somewhat and might give you a number that you might assume is trash..........not always.
