True All Metal No Motion Mode

[FeO2digger]

As always Steve, thank you for your very easy to understand summations of subjects, I can glean information across all boards but get easily confused as everyone uses like terms but dont always apply them in correct context.

I bought and tested 5 different platforms recently and moved on from all but the TDI SL PI unit. Am still looking to upgrade the VLF original Gold Bug platform with a detector that operates in the mode as described above.

The next units I plan on trying are the Tesoro Outlaw, Nokta Impact, and now going to look at the F75 (with boost and DST?) From reading the manuals I know that both the Impact and Outlaw have a dedicated true Non Motion All Metal mode unfiltered channel, and the Outlaw actually has a retune button to deal with drift just as the M Scope Gold Bug did. I believe the Detech Chaser 4.8 khz model may also have capability but is not available in US yet and havent found the manual for this model.

Boost carries over to the al metal side if set on the discrimination side firs.

The Rutus Alter 71 manual says this about Non Motion All Metal mode

1. Motion channel with object identification and Discrimination

2. All metal channel with adjustable operation speed

Signals processed in both channels are directed to the sound control circuit.

The Motion channel with object identification and Discrimination ensures the objects are properly identified. The identification result is directed to the display independently of the sound control circuit, but the sound signal is directed to the sound control circuit only when it is allowed by the Discrimination, Notch or Masking settings. The Motion channel – as its name suggests – requires that the search coil be moved relatively to the object.

The All metal channel reacts to all metal objects or, depending on the soil category (using data from ground balance) and SAT setting, can react to magnetic objects under certain conditions (so called hot rocks, ceramics, bricks etc. and objects other than the soil).

The All metal channel can be completely non-motion (SAT = 0) or it may require the movement of the search coil as the SAT parameter is increased. When SAT is set to 20, the All metal channel works as a „single-filter” Motion channel – where movement is required.

I like the ability to set search frequency very low, and with adjustable SAT is set to 0 a true unfiltered Non Motion static mode?
