Well the retune button on the outlaw has many functions, depending on the mode you're in...
Let's start with all metal...
So In all metal, you have a no motion all metal mode on the outlaw.
Lets say you're using the mode after you found a target in disc and move to AM for pinpointing ( more on the button in disc later...)
So you find that with the stock 8 that it sounds from an inch outside of the coil on either side (10" area)
So you try to find the center based on the tone in the threshold.... But you don't want the center highest point.... Find the center then go just to the side of that and press...
Now the machines threshold sound has gone quiet. If done just off the target it will now only have a sound in the middle of that circle in the donut but also drawing type audio so that you can literally find it to the exact point where the target is.
(If you half press the button in all metal you will have slow retune to better find the area if you're used to other tesoros with motion all metal but takes longer to retune then let's say that vaquero)
Now in disc.....
The button has two features...
Half press is no-motion all metal (but same as no motion all metal by hitting switch.... )
Full press is either retuning by quick press for super pinpointing or just manual retune from the no motion all metal. (Have to go from Full quick press back to half press for this to work. Essentially making it so in disc you can have the same features you do in AM with literally the touch of a button)
If you hold it down straight away in disc you get fast retune pinpoint just like the vaquero.
The coolest part about this is you can go from no motion, to retune/super pinpointing and back to disc with literally the touch of a button.
P.S. NO MATTER WHAT YOU DO AFTER TARGET RECOVERY YOU HAVE TO POINT THE COIL IN THE AIR AND PRESS THE RETUNE BUTTON FULLY... THIS RESETS THE THRESHOLD BACK TO NORMAL. TAKES ONLY A SECOND BUT MANY GET CONFUSED BY THIS.
IT TAKES IT BACK TO FULL THRESHOLD SET BY YOUR DIAL.
