The XP DEUS II 11" Round FMF Waterproof Search Coil transforms your detector's capabilities in ways that aren't immediately obvious from the specs. After extensive field testing, we've found this coil excels in specific situations that make it worth the investment for serious XP Deus II users.
Key Performance Features
The 11" round configuration delivers excellent target separation in trashy areas while maintaining solid depth performance. At 10.8 ounces, it's noticeably lighter than competing coils of similar size, reducing arm fatigue during long hunting sessions.
The FMF (Fast Multi Frequency) technology sets this coil apart from standard single-frequency options. It simultaneously transmits multiple frequencies, giving you better target identification and improved performance in mineralized soil without switching between frequency modes.
Waterproof Design and Durability
This coil handles both freshwater and saltwater environments without issues. We've used it in surf hunting conditions and shallow river detecting with no performance degradation. The built-in skidplate protects the coil face from rocks and debris, though it will show wear over time in rocky terrain.
The unique mounting system clicks securely onto your XP Deus II RC detector with no wobble or play. The connection feels solid even after hundreds of hours of use.
Best Use Scenarios
This coil shines in several specific situations:
- Beach hunting in wet sand and shallow water
- Park hunting where you need good depth with target separation
- Old homestead sites with moderate trash levels
- Creek and river hunting up to full submersion depth
For heavily mineralized ground, the FMF technology handles ground balancing better than single-frequency coils we've tested.
Compatibility with Deus II Models
This coil works with all Deus 2 metal detector configurations including the RC, RC + WS6, and WS6 Master setups. The wireless connection pairs instantly - just power on your detector and the coil is recognized automatically.
Settings transfer seamlessly between coils, so your custom programs remain intact when switching between the stock coil and this 11" round option.
Performance vs Other XP Coils
Compared to the standard 9" coil, you'll gain approximately 15-20% more depth on coin-sized targets. The round shape provides more uniform coverage compared to elliptical designs, making it easier to maintain consistent sweep patterns.
For users considering the larger coils, this 11" size offers the best balance of depth, coverage, and maneuverability. Bigger coils get unwieldy in tight spaces and add significant weight.
Setup and Programming Tips
The coil automatically adjusts frequency ranges when connected, but you'll want to fine-tune a few settings:
- Reduce sensitivity by 10-15% initially to prevent false signals while learning the coil's behavior
- Use the DEEP program as your starting point for maximum depth performance
- Enable ground tracking in highly mineralized soil for stable operation
- Adjust audio response to 3 or 4 to better hear deep, faint signals
What's Included and Accessories
The coil ships with the integrated skidplate and wireless connection hardware. You might want to add a waterproof coil cover for extra protection, though it's not essential for normal use.
Consider the XP warranty extension if you plan heavy use in saltwater conditions, as the wireless electronics are the most vulnerable component long-term.
Real-World Performance Results
In our field testing across different terrain types, this coil consistently outperformed expectations. At a heavily hunted park site, it pulled silver dimes from 8+ inches that previous hunters missed with other detectors.
Beach performance impressed us most - the combination of waterproof design and FMF technology handled wet salt sand conditions that cause many coils to become unstable or require constant adjustments.
Whether you're upgrading from a basic detector or adding to your round search coil collection, the XP DEUS II 11" FMF coil delivers measurable performance improvements in the right conditions. It's particularly valuable for detectorists who split time between land and water hunting.
