Speed Settings

[fortytwo09er]

Okay so having a little bit of a problem with the speed settings. When you go to menu and scroll all the way over to speed where it has slow, medium (factory setting) and fast. When I change the setting from factory medium to either slow or fast I don't see it represented on the screen. I can hear the change happen with slow being quiet and fast being erratic. And that setting holds. But the word doesn't show up on my screen when it defaults back to the default screen. I'm wondering if there's something wrong with my machine and I need to send it back in. This is a brand new machine by the way. I think in fiddling around with it and switching it to slow I have seen the slow "word"  pop up on the screen. But that was only one time. Once you get to that setting in the menu there should be a execute button or an enter button that sets that setting. I've tried hitting the menu button after that and I've also tried just letting the screen time out in default back to the default screen. I just don't know how to make the words show up on the screen just show me what setting I'm in. If anybody can help me with this I'd really appreciate it.

That's entirely normal, it doesn't say the speed on the normal main screen, you select it in the menu's as you have been doing and when you're back at the main screen there will be no speed displayed, if you then go back into the menu and go to the speed setting you should see it sitting on the one you selected indicating it's running on that speed, in my case it's always on slow.

@phruntif you haven't checked it out, try elevating your threshold and setting to medium and see if you can squeek out slightly smaller pieces with the 11" mono...

Thank you very much. While we're on that subject, is that the pulse speed how fast it shoots in and bounces back a pulse to the ground? And it's completely separate from the auto ground balance setting right above it? 

 

Also, what is the fine, medium, large and salt settings doing exactly? I'm trying to understand what functions of the machine are doing what. Thank you so much for the info.

The other fine thru salt is ground type or timing mode as in amount of mineralization that is is the ground. This is what changes the pulses and filtering types to counter different ground effects.

Others have more time behind the Axiom and may have a better explanation however...

Great explanations and reasonable depth response has already gone into this machine as covered in Mr Herschbachs' primer category on the Axiom at the top of this Axiom sub forum. if you haven't gone over all of that you should and then go over it again. There are always hidden little nuggets in the directions and breakdowns of the detectors and sometimes it doesn't sink in until you have had some time behind the machine and gain some perspective of the importance of those little things to you. Not to mention a way better way at presenting and emphasizing the importance of the info than me.

Good Hunting and welcome to the forum.

The Manual is very good. Ground Tracking Speeds:

SLOW: The ground balance values will very slowly track to slowly changing ground conditions.

MED: The ground balance values will track a little faster to changes in ground conditions.

FAST: The ground balance values will track even faster for use in quickly changing ground conditions, but this setting may also produce the greatest loss in detection depth.

Note: Ground Track may reduce detection depth due to slowly tracking to a target, especially with repeated swings over the target and when set to faster settings. Therefore, Ground Track should only be used when changing ground mineralization requires frequent re-ground balancing. Utilize only as much tracking speed as necessary to keep ground responses sufficiently suppressed. If Ground Track is ON but ground balance values remains fairly constant, this indicates ground conditions may be stable enough to switch Ground Track OFF.

This is one of the points that I'm trying to understand. Is the slow, medium, fast related to ground balance or something totally different. Because when the automatic ground balance is set to OFF the speeds still effect the machine. In other words, if ground balance is OFF and you select the FAST speed you can definitely hear the machine get more erratic. If it was a faster tracking ground balance you would think that the machine would get quieter BECAUSE the machine is adapting to the ground faster. And if the slow, medium, fast is related to the ground balance function why does it still work and change the machine when the automatic ground balance is set to OFF?

That's because the ground tracking values remain at their current settings when you switch it to OFF.  

For example, I set it to slow, then OFF for best results in my area with is mild soils.  In my very mild area's, I do a factory reset, then set it to off so ground balance is essentially disabled completely as it has no ground balance values already determined.

Axiom has Speed settings: Slow/Medium/Fast and it has Ground Track Speed settings: Slow/Medium/Fast

Two entirely different things.

Phrunt quoted the Ground Track Speed settings information from the manual.

Here is the Speed (actually similar to VLF recovery speed) information from the manual:

"Speed - This adjustment refers to the speed at which you scan the coil as well as target recovery speed, also known as Reactivity. Set the Speed adjustment according to your preferred scanning speed, target recovery speed/reactivity, and EMI noise conditions as described below.

Press the MENU button until SPEED is selected, then press MENU Plus (+) or Minus (-) buttons to choose between Slow, Medium or Fast scan speeds.

SLOW: This setting will produce the smoothest and quietest operation thereby ensuring excellent depth and sensitivity, but will require a slow coil swing and will have less ability to separate adjacent targets due to slower reactivity.

MED: This is the default setting and should be used as a general-purpose selection for moderate coil swing speed. This setting will also provide increased ability to separate adjacent targets due to its medium reactivity. You may notice an increase in EMI and noise chatter compared to the SLOW setting, but will still provide good depth and sensitivity.

FAST: This setting allows a faster coil swing to search an area more quickly and will have increased ability to separate adjacent targets due to faster reactivity, but may also increase EMI and noise chatter, making it more difficult to discern faint targets."
