Your metal detector is capable of more than you think. Manufacturers release firmware updates to fix bugs, improve target ID, improve audio, add features, and make detectors more stable in different ground conditions.
But a lot of detectorists are still using the software that came with their machine, either because they don’t know there’s an update available or because they are worried about interrupting the process.
Normally, updating is simple if you update with the right procedure for your model. The most important thing is to know the software that applies to your detector, have the right cable or accessories, and let the installation finish without interruption.
This guide explains how firmware updates work, what to check on popular Nokta, Minelab, XP, and Garrett detectors, and what to do if an update fails.
Quick Answer: How Do You Update a Metal Detector?
The safest way to update your metal detector is to find out your model and current firmware version, review the official release notes from the manufacturer, charge your detector, and use the correct update tool and cable.
- Identify your exact detector model and installed firmware version.
- Visit the manufacturer's official support page.
- Read the release notes to understand what the update changes.
- Charge the detector and any accessories that need updating.
- Download the official update utility and use the required cable.
- Follow the on-screen instructions without interrupting installation.
- Restart the detector if instructed and verify the installed version.
Important: Not every model uses the same updater or cable. Always follow the instructions for your exact detector.
What Is Metal Detector Firmware?
The firmware is the software that governs how your detector works. It helps manage things such as signal processing, target identification, audio responses, wireless connections, and settings.
When a detector is released, problems are found that can be fixed by a firmware update. Depending on the model, it may add new features or improve existing ones.
- Target identification: Refinements to how the detector classifies targets.
- Target separation: Changes that may help distinguish desirable targets from nearby iron or trash.
- Audio performance: Changes to tone behavior or wireless audio stability.
- Ground performance: Improvements for particular soil or beach conditions.
- Bug fixes: Corrections for inconsistent behavior or software errors.
- New features: Additional search options, controls, or settings.
What Can Firmware Updates Actually Change?
Sometimes manufacturers make meaningful changes through software instead of requiring owners to buy another detector.
For example, in the original Legend, Nokta’s official release notes have documented changes to functions such as Beach mode, pinpoint stability, and Iron Filter behavior from version to version. All terrain modes in Minelab’s MANTICORE software upgrades now include a stabilizer setting, while Goldfield functionality has been improved. Custom shortcuts and changes to ferrous target detection are also part of the upgrades.
These examples show why it is important to check your firmware; an update can change the way in which you use your detector, not just fix a minor technical problem.
Start with the manufacturer's official instructions:
- Nokta The Legend software updates
- Minelab MANTICORE software upgrade
- Minelab EQUINOX 700 and 900 software upgrade
- XP metal detector updates
- Garrett updates and upgrades support
Nokta Legend, Legend 2, and Score: Check Your Software First
Nokta owners should start at the official update page for their specific detector. Do not assume that the update process is the same for the original Legend, Legend 2, and Score series.
How to Update the Original Nokta Legend
Nokta has a dedicated Legend update page, with release information and update tools. Identify your installed version and read the notes for the available release before downloading anything.
- Record the current software version, if displayed.
- Open the official Nokta Legend update page.
- Download the appropriate update tool for your computer.
- Connect the detector using the required cable and follow the on-screen instructions.
- Wait for the process to finish before disconnecting the detector.
- Follow Nokta's post-update instructions and check the installed version.
What About the Legend 2 and Score?
Install software for your exact model, not for another detector. Use the official support resources.
Legend 2 is a different hardware generation, not a firmware update for the original Legend. An update cannot add hardware and features that an older machine does not have.

Why the Correct Cable Matters
On supported Minelab models, the charging cable also serves as the data connection. A computer will not recognize the machine if the cable is missing, damaged, or incompatible.
If your cable is missing, check detector parts and battery and power accessories for compatible options. Confirm compatibility with your exact model before ordering. A cable that physically fits is not necessarily the correct data cable.
XP DEUS II and ICON FMF: Remember the Remote and Coil
XP’s wireless ecosystem can make software updates less transparent, as different components have their own software. There are separate updater resources on the official XP update page for the ICON/ICON X, DEUS II, and other platforms.
Updating the XP DEUS II
The XP DEUS II updater is the software used to update the components like the remote, the headphones, the coil, etc. Exactly how you do this depends on your setup and what updates are available.
- Open the official XP updates page.
- Select the DEUS II updater and follow the instructions for your setup.
- Check which components require updates.
- Connect and update each component as instructed.
- Confirm that the required components are running the intended software version.
Updating the XP ICON FMF
XP shows the ICON/ICON X updater separately from the DEUS II updater. Use the ICON-specific instructions and do not assume that a DEUS II update package will work with the ICON FMF.
For more information about the detector, read the XP ICON FMF guide at Detector Warehouse.
If you need compatible accessories, browse metal detecting headphones and the relevant parts and accessories. Verify that an accessory is supported by your specific XP detector before purchasing it.
Garrett Vortex VX5, VX7, and VX9: Check the Startup Screen
Garrett has made it easy to determine your Vortex firmware version. When you turn on the detector, the startup screen will show the model and version of firmware installed.
- Power on your Vortex.
- Note whether you have a VX5, VX7, or VX9.
- Record the firmware version shown on the startup screen.
- Visit the Garrett Vortex Owner Center.
- Select your model and compare your version with the current official release.
- Follow Garrett's instructions if a newer update is available.
Garrett provides firmware resources and update instructions for specific models. Check the current requirements for your computer and detector before you start.
It is also important to differentiate between a firmware update and a feature upgrade. A firmware update installs supported software changes to your detector. An upgrade to digital can give eligible Vortex models additional capabilities. These are not necessarily the same process.
See the official Garrett updates and upgrades support page for current instructions and eligibility.
Before You Update: Essential Checklist
- Check the exact model: Confirm the model name and hardware generation.
- Read the release notes: Understand what changes and whether the update is relevant to you.
- Charge the detector: Follow the manufacturer's battery and power requirements.
- Check accessories: Remotes and wireless headphones may need separate updates or charging.
- Find the correct cable: Make sure it supports the required data connection.
- Use official software: Avoid unofficial files and firmware intended for another model.
- Keep the connection stable: Use a reliable computer connection and follow the manufacturer's USB guidance.
- Save custom settings: Record programs and settings before any recommended factory reset.
- Allow enough time: Do not start immediately before a hunt or when you need to disconnect your computer.
A low battery is a reason to postpone an update, not to rush it. If your detector or accessory requires a particular cable or power setup, follow the manufacturer's instructions rather than improvising.
What If a Firmware Update Fails Halfway?
An interrupted update can be worrying, especially if the screen goes blank or the detector does not start properly. But not every failed update means the detector is irrevocably damaged. The proper recovery procedure is device-make and model dependent.
The Computer Does Not Recognize the Detector
- Confirm that you installed the correct update utility.
- Check that the cable supports the required data connection.
- Inspect connectors and contacts for dirt, moisture, or damage.
- Connect directly to the computer if the manufacturer recommends it.
- Close duplicate updater windows and restart the official utility if instructed.
- Restart the detector only as directed by the manufacturer's troubleshooting instructions.
The Update Stops or the Screen Goes Blank
If the updater reports an error or the detector becomes unresponsive:
- Record the error message and the point at which the update stopped.
- Follow the manufacturer's official recovery procedure for your model.
- Reconnect the detector only when instructed.
- Retry the update if the official utility identifies the detector and offers a recovery option.
- Contact authorized support if the recovery procedure fails.
Do not repeatedly try unrelated firmware files, force a reset without instructions, or use another model's updater.
The Detector Works, but the Version Has Not Changed
Check to see if the installation was actually completed. Run the official updater again, check the version you have installed, and see if there is another update available.
Releases may not apply to all models or revisions of hardware. If the utility reports that your device is up to date, make sure you selected the correct model and release page before trying to install again.
Would a Protection Plan Help?
A protection plan can provide peace of mind for eligible equipment failures, but don’t assume all plans cover failed firmware updates, accidental damage, or software-related issues.
Check plan exclusions, claim duration and process, and actual coverage terms before you buy. If the detector does not respond after an update, contact the manufacturer or authorized dealer first and follow their instructions.
Should You Update Your Detector or Upgrade to a New Model?
Firmware updates fix different problems than hardware updates. A software update can add to supported functionality, but not all the hardware capabilities of a newer detector.
| Your Situation | Best Next Step |
|---|---|
| Your detector has a bug addressed by a newer release | Review the release notes and consider updating. |
| An update adds a feature you want | Check model compatibility and install it if appropriate. |
| Your detector works well and the update offers no relevant changes | You may choose to wait. |
| Your current detector lacks hardware features you need | Compare newer models and their specifications. |
| Your computer cannot recognize the detector | Troubleshoot the cable and updater before considering a replacement. |
| You are considering a paid digital upgrade | Check which features it unlocks and whether your model is eligible. |
For example, the original Nokta Legend and the Legend 2 are not the same in hardware and specs. You can't make it a Legend 2 by flashing the latest original Legend firmware.
If you are comparing hardware options, explore the Nokta Legend collection or review the Minelab MANTICORE before deciding whether an upgrade suits your detecting style.
Final Thoughts
Keeping the firmware of your detector up to date can help you benefit from manufacturer fixes, refinements, and new features. The best practice to get into is always to check the official release notes for your model. Don’t assume that every update is going to improve performance the same way.
Check the version first, charge the equipment, find the right cable, and then use the official update utility. If something does go wrong, don't mess around with firmware files—use the manufacturer's recovery procedure.
