Ok since you asked here we go!! And thanks for stepping up tp the plate as well!!
What is going on between coin fast and coin deep? Is it some kind of boost process with less ID filters in coin deep allowing non ferrous items to come through the matrix or depth that is already programmed into the ORX that you cannot adjust?
If you put the exact same coils and run the exact same frequencies on the ORX vs Deus will both machines react to targets that are at the same depth? In other words, are they equal on depth?
It seems to me when I turn the ORX it saves the settings and frequencies I used last is this correct?
When I pair up the wireless headphones which I have not used yet, will the ORX remember this or will I have to pair them up every time I use the wireless headphones?
i think that is about all of the questions I need answered at the moment.
Coins Fast vs. Coins Deep
Coins Fast is running additional iron filters under the hood for low reactivity settings. On Deus this is called silencer and is adjustable and you can turn it off. On ORX you can't turn it off. It helps make the machine break up falsing iron or mixed ferrous signals like bottlecaps. The drawback is that it can cause masking of non-ferrous near ferrous targets and can break up non-ferrous signals in highly mineralized dirt, affecting depth. If you run Coins Fast at reactivity 2.5 or 3, the silencer filter is turned off. Coins Deep does not use the silencer filter at all.
Coins Deep also has signal processing that enhances deep target signals at the expense of a little more chattines than Coins Fast. I think your round ball story illustrates this clearly. Coins deep really pulled out that deep round ball target signal out of the muck that was less audible in coins fast.
ORX vs. Deus Depth
Use of exact settings and exact coils should result in no depth differences between ORX and Deus. The thing is there are some settings you can tweak on on Deus that you can't on ORX (transmit power, extreme reactivity settings, silencer settings, Ground Balance tracking, ID norm off, and pitch tones to name a few) that will enhance Deus performance over ORX under certain circumstances.
Remembering Settings
From my experience, the changes from the default settings on the built in programs are lost when you turn off the controller. If you want to save custom user settings you have to save the modified Gold or Coins program to one of the two available user program slots.
Wireless phones
Once paired, the ORX detects and connects to the wireless phones automatically after the controller boots up and the phones are turned on at the beginning of each detecting session. Pretty seamless and reliable. One of tge great features of Deus/ORX is tge wireless phones, so take advantage of it. The puck is removable and can be attached to other 3rd party compatble phones if you prefer full suze phones, for example.
Other tips:
Yes, use that disc. The default setting is good. Anywhere fro 7 to 10 is ideal. Avoid the temptation to go with lower or zero disc settings. It does nothing to improve depth and you lose accuracy on the the iron probabilty indicator. If you need to hear the iron to ascertain whether you are near tge remnants of a structure, just keep iron volume on.
Keep sensitivity near the default. Cranking it much higher than 90 doesn't give you much in the way of deoth performance and really cranks up noise susceptibility. Lower sebsitivity if needed to reduce chatter. In real thick iron junk, crank down on sensitivity (go as low as 80 or so) and that can help lower ferrous overload on tge coil and can help partially maked, shalliw keepers pip out of the muck. This is sonetines referred to as sifting and us counter intuitive to most detectorists as we seem to be overly obsessed with depth.
28 to 30 khz seems to be the sweet spot for reluc hunting for me. The 9" round HF is ny fav coil. For coun shooting, I bump frequency down to 14 khz.
Experiment with gold mode, the pitch tone it uses can really pull out some marginal deep targets, though you are reliant on the visual display for target ID. It also does not use discrimination but something called iron audio rejection, which works similar to the silencer filter (not a fan, so I rarely use it). The default for IAR is 0 (off), so if you want to go with a pseudo all metal mode with ORX, then try tge gold mode.
Gary's Deus/ORX skill school videos are great for learning the various settings, but avoid using his specific settings because they are set up for UK hunting and conditions. He likes to run with zero disc for some reason (which is counter to how XP designed Deus/ORX to run), so I do not recomnend emulating every aspect of his custom settings unless you realky know how that is going to affect oerformance on your target objectives and soil type (UK soil ground phase pretty is pretty constant at tge defaukt ORX GB default settingm not the case in the US).
