The current software for the Minelab Equinox 700 and Equinox 900 is build 1.79.0-3.3.4, released in June 2024. If your detector still shows an earlier version, it is worth four minutes with a laptop. This release added an aggressive new Iron Bias setting that opens up hunted-out iron sites, and a continuous noise cancel that makes EMI-heavy ground workable. It is free, your settings survive it, and it can be rolled back if you ever want to.
Which detectors this covers
The update is for the Equinox 700 and Equinox 900 only. The Equinox 600 and 800 are earlier hardware with their own older software; the 800 is discontinued and the Equinox 900 is its current replacement. The X-TERRA PRO received a separate, smaller update at the same time, covered in our X-TERRA PRO software update post. Alongside the two headline features, the release includes small stability fixes for infrequent use cases.
Iron Bias -1: aggressive target unmasking
The headline feature is a new Iron Bias setting of -1, one step below the previous minimum. It pushes target separation further than the Equinox could go before, unmasking non-ferrous targets that would normally stay silent next to a rusty nail or a piece of farm iron.
Use it at trashy sites with heavy iron contamination, at frequently hunted locations where the easy targets are gone and the rest are hiding, and at old home sites, farm fields and battlefield ground. The trade-off is more chatter and more iron breaking through, so it rewards someone who already reads their Equinox well. On a Civil War camp that has been hunted for decades, running -1 with a slower recovery speed turned up three bullets and a button that had been masked before.
Continuous Auto Noise Cancel
Instead of a single noise cancel pass, you can now press and hold the Accept/Reject button with Noise Cancel selected in the Settings menu, and the detector keeps sampling every channel for as long as you hold it. A longer sample catches interference that comes and goes, which a one-shot cancel misses. Near a radio tower that used to make detecting impossible, a 30 to 60 second hold found clean channels and the machine stayed stable for the rest of the session. Run it when you arrive at a site and again if chatter picks up.
Recommended settings by situation
- Heavy trash: Iron Bias -1 with a lower recovery speed. Expect to dig more iron while you learn the new audio signatures.
- EMI-heavy areas: continuous noise cancel for 30 to 60 seconds on arrival, then periodically.
- Beach: Iron Bias -1 helps separate good targets from bottle caps and small iron; continuous noise cancel handles nearby electronics.
- Relic hunting: Iron Bias -1 with a lower discrimination pattern on colonial and Civil War sites where iron masks everything.
How to install the Equinox 700 and 900 update
The update runs through the Equinox 700/900 Minelab Update Utility, a small free program for Windows 10 or macOS 10.15 and later. Connect the detector to a USB 2.0 port with its magnetic charging cable, coil attached and detector switched on, and the utility does the rest.
- Plug straight into the computer, not through a USB hub, and check the magnetic connector is clean and seated. A loose cable is the most common cause of a failed update.
- The screen goes blank for a stretch while the core software installs and a green LED blinks. That is normal.
- Installation takes about four minutes, then the detector reboots and the utility tells you to disconnect.
- Your user settings carry over.
- The utility keeps every released version, so you can roll back from its menu if you ever need to.
If the update is interrupted, the detector may power up with a blank screen and a fast-blinking green LED. That just means it is waiting to finish. Restart the utility, reconnect, and run it again.
Why this update matters
Iron Bias -1 and continuous noise cancel address the two biggest day-to-day problems in detecting: separating targets in iron trash, and dealing with interference. If your detector has not been updated since June 2024, you are leaving capability on the table.
