The new XP DEUS II Elliptical 9.5" x 5" HF2 FMF High Power Precision Coil brings enhanced detection capabilities to your detector, but there's one critical step before you can use it: updating your DEUS II firmware. Skip this step and you'll miss out on the coil's advanced features.
Why the DEUS II Update Is Essential
This isn't just a nice-to-have upgrade. The HF2 FMF coil uses advanced communication protocols that older firmware versions can't handle. Without the update, your detector won't recognize the coil properly—or at all.
The high-power coil delivers ultra-sensitive detection in mineralized ground and tight spaces, but only if your DEUS II can fully communicate with it. That requires firmware version 2.0 or newer, depending on when XP releases the coil.
If you're running the WS6 Master configuration, the WS6 Module handles coil communication, so it needs the firmware update too.
How to Update Your XP DEUS II Firmware
The update process is straightforward, but you'll need a computer and stable internet connection. Here's the step-by-step:
Download the Update Software
Head to XP's official website and download the XP DEUS II Update utility. They provide versions for both Windows and macOS. Don't use third-party update tools—stick with the official software to avoid bricking your detector.
Charge Everything First
This is critical. Make sure your remote control, WS6 module (if you have one), and headphones are fully charged before starting. A dead battery mid-update can cause serious problems.
Run the Update
Connect your detector to your computer using a quality USB cable. Launch the update utility and follow the on-screen prompts. The software will detect your detector and walk you through each step.
Don't disconnect anything during the update process. Let it run completely—it usually takes 10-15 minutes depending on your system.
Pairing Your New HF2 FMF Coil
Once the firmware update completes, you'll need to pair the new coil with your detector. Navigate to the coil pairing menu on your DEUS II and look for the HF2 FMF coil in the available devices list.
The pairing should happen automatically once the coil is connected, but double-check that your detector recognizes it correctly. You'll see the coil model displayed on your screen.
Optimize Your Settings
After pairing, explore the coil's frequency range and sensitivity settings. The HF2 FMF coil operates at higher frequencies than standard XP DEUS II coils, making it excellent for small gold and jewelry in trashy areas.
Start with the factory presets, then adjust based on your hunting conditions. The elliptical shape excels in tight spaces between trash targets.
Troubleshooting Common Update Issues
If the update fails, check these common problems:
- Use a different USB cable—cheap cables often cause connection issues
- Close other programs that might interfere with the USB port
- Temporarily disable antivirus software during the update
- Make sure your detector's battery isn't low
If you're still having trouble, XP's technical support can walk you through the process. Don't attempt to force the update or use unofficial firmware.
What to Expect from the HF2 FMF Coil
Once everything's updated and paired, you'll notice the coil's strengths immediately. The elliptical shape lets you work around fence posts, between rocks, and in other tight spots where round coils struggle.
The high-frequency operation makes it particularly effective on small targets in mineralized soil. Beach hunters will appreciate its performance on fine jewelry in wet sand.
The XP DEUS II Elliptical HF2 FMF Coil represents a significant upgrade in precision detecting, but only if your detector's firmware can support its advanced features. Taking 30 minutes to update your system ensures you'll get every bit of performance this coil offers.
