I have a new Delta 4000 and can't seem to find the All Metal A1 and A2 options. Did Teknetics do away with the two options on the newer models? I can only switch between All Metal and Discriminate modes. Thanks
From the manual:
2. ALL METAL Mode
All Metal Modes of operation are, like discrimination, motion modes of
operation. The visual target identification system will identify targets, similar to
the Discrimination Mode, except that target rejection is not possible in any All
Metal Mode.
There are two different All Metal Modes, identified as A1 and A2.
The best All Metal Mode for you to select depends on the ground conditions
where you are hunting.
A1 has more default sensitivity, about an inch more on a coin-sized object, but
will sound off over more highly mineralized ground.
A2 is more tolerant of ground conditions, but will be less sensitive over less-
mineralized ground. The two modes also have different audio characteristics.
A2 will provide better target separation, as the sound covers a “tighter” area as
you cross over a target.
In both A1 and A2, all types of metal objects induce a sound which varies in
pitch and volume according to the size of the object and its distance from the
coil. For example, a larger object close to the coil will induce a loud, high-
pitched tone. A small object, farther from the coil will induce a lower-pitch
lower-volume tone.
Use an ALL METAL Mode for maximum sensitivity to buried targets.
