what does deep do ??????

[Anonymous]

i would like to know how deep works and is it normal to be able to only move at a snails pace.i only use it in clean places and switch to fast in high trash. also ow much more depth do you get with deep??????

Deep will cause a more intense sound from a faint target. <span style="background-color:#ffff00;">A faint target can be very deep such as a good coin or a tiny piece of aluminum right on top or just below the surface of the soil.</span> Deep only places emphasis on faint targets and does not have anything to do with a strong one. With Deep on and in heavy trash where there may be tiny bits of aluminum or other such trash one needs to overlook the small shallow or surface trash that give a faint sound.
I don't use Deep but prefer to run the Audio gain at 10 and judging from the depth I find coins and relics this is doing OK for me. <span style="background-color:#ffff00;">You did not ask but FAST shortens the time it takes for the electronics to recover from a null over rejected trash or a positive hit on a target.</span> This will help to get clean clear hits on targets that are located very close to each other.
You cannot move at what I think of as a snails pace which would be just moving the coil at say 1 or 2 inches per second. There has to be relative motion between the target and coil for detection to take place except in pinpoint. The motion of the coil can be moved at the slowest rate when the sensitivity is set to manual. In Semi-auto sensitivity the motion must be slightly faster. The speed in both modes are what I would call very comfortable. There is no need to sweep the coil at a very fast rate of speed although the depth of detection is the same. The primary problem with sweeping to fast is we might miss a faint target simply because we miss the quick faint hit. Another reason is the null from a rejected target may cause the threshold to be silent when we sweep over other targets so a slower sweep give the electronics time to recover before another target is hit. Also, if we hit a target that sounds we might miss a second target as the two sounds are blended together. <STRONG>Sweeping slow allows the user to seperate sounds and also to give the circuits time to recover from a null.</STRONG>

well, as you will see with my question that it takes me a long time to understand some things! so here goes the question. what exactly are you talking about when you mentioned <span style="background-color:#ffff00;">"the null from a rejected target may cause the threshold to be silent when we sweep over other targets"? </span> i thought that's what happened when the threshhold would go silent! you get a null or silent threshold! as you can see i'm totally lost now! <img src="/metal/html/confused.gif" border=0 width=15 height=22 alt=":?"> </span>

Refer to page 86 of the Explorer II manual
WHAT FOLLOWS IS MY UNDERSTANDING OF THE FAST ON OPERATION
Each time a target is detected the processor accumulates and analyzes the data associated with the target. Then the target information is presented to the hunter.
If the target falls into the "discriminated out" range, then the null is generated instead of a tone. This lets the hunter know that rejected target has been detected.
If the hunter selectes the Fast on mode, then the processor will not spend as much time analyzing the data and generating the tone (or null). The advantage of this setting is that if two targets are close together, then the hunter will see both targets. The disadvantage of this setting is that the target tones tend to be "cutoff" more quickly and the target ID accuracy may suffer a bit.
Hope this helps. HH,
Glenn

That is what happens so consider this. Let's say we sweep the coil and hit 2 targets that are in line one after the other. Assume the coil hits the first target and it is a piece of trash metal that causes the threshold to null. The threshold goes silent and then has to recover to a slight sound before we hit the next target or we miss the next one becasue the threshold is in null. <span style="background-color:#ffff00;">If the threshold is null from target one when it passes over target two then we miss target two. </span> <span style="background-color:#ffff00;">The bottom line is we want the threshold to recover between each target</span>

Thanks Cody and everyone else!! You guys are great!!! I just wish I had come across this web site earlier. I am truly amazed at how much information is generated on this site!! Have you ever thought about publishing your information? I can say that I'm not alone in that I would have me a copy or two! Thanks for the great info and time you guys put into this forum.

So so true......that is why I don't use fast at all cause it is to short of a tune I have a hard time interpreting it myself....I only use DEEP and Yes I might miss a few but I still dig goodies and am more than positive it is good....and Deep is more accurate than fast mode I think...fast if in computer terms should still be accurate.....but technoligy will catch up soon. Come on Minelab perfect this beast it has potential to be a gold mine! I love my Explorer just the same!
