Minelab Equinox 900 Settings for Target ID
Equinox 900 uses 119 target positions from -19 through 99. That expanded scale improves resolution, but IDs remain conductivity evidence affected by depth, angle, alloy, ground and nearby targets.
Bottom line
Build a local -19–99 chart before editing discrimination
Use the correct mode, Multi-IQ, Noise Cancel and ground procedure, then scan regional coins and common trash. Record ranges from two directions and keep the low/mid region open when jewelry or unfamiliar coins matter.
Field guide
Starting points and hard limits
| Situation | Baseline | Action | Caution |
|---|---|---|---|
| Modern coin park | Park 1 / Multi-IQ | Factory pattern first | Odd coins/jewelry can overlap rejection |
| Mixed historic field | Field 1 | More open acceptance | Log regional alloys |
| Suspected iron false | All Metal shortcut | Cross-sweep ferrous audio | Deep coin may flash low |
| Jumpy deep response | Same mode | Slow sweep; lower instability | Dig repeatable two-way audio |
Method
Use a controlled workflow
Stabilize first
Noise cancel, balance and sensitivity before interpreting IDs.
Confirm the scale
-19 to 0 is the ferrous region; 1–99 non-ferrous conductivity.
Calibrate locally
Test actual coins, foil, tabs and caps in the soil.
Reject last
Notch only measured nuisance ranges after checking valuable overlap.
Decision analysis
What actually changes the result
The scale is model-specific. Equinox 600/800 charts using -9–40 are not direct Equinox 900 charts.
More segments do not guarantee object identification. They provide finer conductivity steps while weak/mixed signals still spread.
Mode affects response. Park, Field, Beach and Gold weight targets/ground differently, so record mode with every ID observation.
FAQ
Seven questions specific to this page
What is the Equinox 900 Target ID range?
It uses -19 through 99, totaling 119 target positions.
Which IDs are ferrous?
The low region from -19 through 0 represents ferrous response on the scale.
Can I use an Equinox 800 ID chart?
Not directly. Equinox 900 uses a wider scale, and values cannot be copied one-for-one.
Why does a coin ID change between modes?
Mode processing, frequency weighting, ground handling and recovery defaults influence the response.
Should I reject every negative flash?
No. Deep or masked non-ferrous targets can be pulled toward iron; use two-way audio and All Metal checks.
Does a stable high ID guarantee silver?
No. Copper, aluminum and other conductive objects can occupy high ranges.
How should I build a local chart?
Record ranges for actual coins/trash in air and ground, at different angles and depths.
