Recovery ~ Response ~Ace ~ Xterra ~ Tesoro

[trueblue]

am interested to know from those who have used both the Ace & the X Terra , which one has the faster Target Response and Recovery speed of the two .

Now ya probly going to ask which X Terra 30 ~ 50 ~ 70 ? do they differ in there performance when it comes to Response and Recovery speed ?

Same goes for the Ace's the 150 & 250 are there any differences in the R & R speeds ?

I find the Ace 250 lacking well behind in recovery speed when pitted against any of my current Tesoro's { Eldorado Umax ~ Silver Umax ~ Tejon }

Same question for those who have used the Tesoro Umax or H.O.T detectors & the X Terra's what detector rules when it comes to R & R between these two ?

Hi Trueblue.
The X-Terra's have a faster recovery speed than the Ace. I find that I can make a 4 foot pass in 1.5 secs with the X-Terra, but 1.6 seconds with the Ace. If these detectors are swung faster than this, then you only hear targets under the receive (inner) coil As you can see, the difference is not large, but it is there. I don't know if the prospecting mode on the 70 would make a difference.

I think ya miss understand me Mick or I havent explained well enough ,

the recovery speed that Im refering to is the time that it takes the detector to recover from a signal given on a target while sweeping in time to signal on the next closest target , to catch its breath so to speak

and response as the time it takes for the detector to produce a signal when passing over any given target

for example on recovery if I put a small rusty pony shoe on the ground then 3 -4 inchs lie a cion , then sweep over the target from the shoe side first so is its my first target "normal sweep speed " , the ace 250 even in AM mode will not have recovered in time to even signal on the coin " it will be masked "

using a similar sized coil "same sweepspeed " on any of my Tesoro's will hit hard on both Targets in AM and if discing irion out will null on the shoe but hit hard on the coin

now given that most recommend the 250 is better suited to a faster sweepspeed and the Tesoro better suited to a slower sweepspeed , this would make the Tesoro more able to handle masking and so be the better performer in trashy sites , but what I would like to know is how does the Xterra range of detectors stackup angainst Garrett and Tesoro when it comes to R&R

I would like to add that my NORMAL sweep speed is about 2 secs for about a 4' sweep or there about

Yeah, I misunderstood you, too. On the Tesoro forum I stated that I didn't see too much difference in my Ace and Silver, although the Silver pinpoints in motion at a normal speed and I have to slow the Ace down slightly to pinpoint in motion. Haven't tried that test.

One also misses targets with fast sweeps.

This is almost on the subject; I own a minelab eureka gold and a GTI 2500 and I noticed my minelab is lots faster than all of my detectors, I have not done a time and motion study as yet, my fisher does not react as fast nor do any of my other detectors minelab just uses some very fast programming for there Eproms, I have covered alot of ground with it, but I do like the GTIs display and voice and backlight ! Now if someone could just combine the two for a super detector that would be great!

Here's my question. Would a target be missed by the Ace in a lower disc level such as relic mode.? I noticed that the Ace, although somewhat slower will COMBINE two targets as one if the disc level is not that high-so my thought is that the disc level is a huge determining factor in whether a target is missed. I think that is one reason I had such a big day a couple months ago (Smokin' Ace post). So I wouldn't really care if the Ace didn't give two distinct signals at a normal sweep speed as long as there was a signal generated-then I could slow down and they would probably separate.

Relic mode is only notching out the lower iron range. So I doubt you would miss too much
desirable stuff. Might miss a few iron objects.
As far as "distinct signals", it will ID fairly close objects. So getting a double tone
with two different ID's is pretty common.
But also some objects with rust or corrosion can vary to the ID and tend to
bounce around. Rusty nails are the worst at this I think. You bang the low end
hitting the iron that is not rusted, but you also bang the coin range hitting
the rust that is on the surface of the nail. The rust is much more conductive
than the original iron.
Nothings ever a sure thing, so I tend to run wide open most of the time.
I don't want to miss anything, but I also like knowing what iron is in the
ground too..
BTW, when you are in a custom mode, the machine is still actually reading
wide open. The only thing the notches do is turn off the tone for that
particular conductivity. But if you watch the display, you will notice it's
still responding to everything.
So that can tip you off to iron without having to listen to the beep..
BTW, I've never considered the ace 250 to have a slow response.
Quite the opposite really. I've never really been able to "outswing" it to
the point it started missing anything. And a fast swing goes deeper than
a slow one on the ace machines.
But I go pretty normal speed most of the time.. I'm too lazy to get too carried
away..

NM5K, you're thinking like I was thinking, but what he meant was the readjustment time in between targets and not whether the detector would pick up anything at a fast speed. In other words if a dime and a tab were 1-2" apart, the recovery time might only pick up one target and if the tabs were being eliminated, the Ace wouldn't recover fast enough to detect the dime whereas the Tesoro might. And that's what I meant about the relic or even the jewelry mode, you wouldn't even have to worry about this because the disc setting would be low enough to get eilther signal, although at a fast sweep speed only one signal would come through. Then, by going back slower and giving the Ace more time you could probably separate the two. Yes, you're absolutely right. I can't outrace my Ace! Anyways, I haven't been concerned enough to make the test. If I were to worry about Dankowski's target masking, the Ace's recovery speed, no ground balance adjustment,whether the target was aslant, the humidity in the air, etc., I'd never go anywhere and just plain have fun.
