I'm in the UK also, no better all rounder for our type detecting, i'll be going back to an RA71 very soon, unless the new ML is something special !!
Basically it's very similar in operation to a Deus, slow the machines reactivity down, use minimum disc and masking etc and go deep, or speed it up to sift between shallow iron etc.
I actually think i could run my RA71 at a lower reactivity in 18khz than i could with the Deus, maybe Tnss could check this out as he has both at the moment, going below reactivity 2 on my Deus in 18khz seems to chop the signal?
I haven't done super I depth comparisons of Deus LF coils and Rutus as far as reactvity settings go.
The 2 detectors are scaled different obviously.
Deus reactive setting 0-5
Rutus reactive setting 1-8
I do think Rutus reactive setting more or less equals Deus set to 2 reactivity.
In much high mineral soil adjusting both upwards a bit might help with performance/detection.
Btw, XP in a way missed the boat with original version release of Deus and subsequent versions 3.xx. Meaning they added reactivity setting 2.5 with versions 4 update.
Why?
Because evidently XP seen a hole with Deus,,,from a separation/unmasking and depth standpoint.
I could see this too when I ran versions 3.2 bunches.
How did I do and what did I witness.
Some nonferrous targets in super polluted with iron sites,,,I could run reactivity 2 18khz using 9" coil, and with ultra slow, precision coil sweeps I could get targets...Reactivty 3 setting would give no signal, or a very weak signal.
I fully suspect if I would have marked these targets, and later used version 4 and 2.5 Reactivty these same targets could be acquired more easily with coil sweep speed and or with more error in with coil height.
