The XP Deus II HF2 Coil: Your Secret Weapon for Tiny Target Recovery
If you’re serious about finding the smallest gold nuggets, ancient hammered coins, or those elusive micro-jewelry pieces, the XP Deus II HF2 coil deserves your attention. This 5-inch round high-frequency coil transforms your Deus II into a micro-detection powerhouse, and after months of field testing, I can tell you it’s not just another accessory – it’s a great option.
Why High Frequency Matters for Small Targets
The HF2 operates at 40-80 kHz, significantly higher than the standard Deus II coils. Here’s why this matters: higher frequencies provide better sensitivity to small conductive targets. Think of it like this – lower frequencies penetrate deeper but miss tiny objects, while higher frequencies excel at detecting small items but sacrifice some depth on larger targets.
The HF2 strikes an excellent balance, maintaining respectable depth while dramatically improving your chances of hearing that faint whisper from a gold stud earring or a delicate medieval brooch pin.
Real-World Performance: What You’ll Actually Experience
In my testing across various soil conditions, the HF2 consistently outperformed larger coils when hunting for targets under 2 grams. On a recent permission with scattered Roman and medieval activity, I recovered several tiny bronze artifacts that my Deus II with the 11-inch coil had completely missed during previous visits.
The coil’s 5-inch diameter makes it very maneuverable in tight spaces – perfect for those awkward spots between tree roots, around foundations, or in areas with high metal contamination where you need surgical precision.
The 5-inch round design provides excellent ground coverage while maintaining pinpoint accuracy. Unlike elliptical coils that can create elongated detection patterns, the round shape gives you a consistent search area, making it easier to narrow down target locations.
Who Should Consider the HF2 Coil?
This coil isn’t for everyone, and that’s okay. You’ll get the most value if you fall into one of these categories:
Beach hunters chasing thin gold chains and small jewelry will appreciate the enhanced sensitivity in wet sand conditions. The high frequency cuts through mineralization that often masks tiny targets on saltwater beaches.
Relic hunters working sites with high iron contamination benefit enormously. The smaller coil size and higher frequency help you separate good targets from iron trash more effectively than larger coils.
Gold prospectors hunting for sub-gram nuggets in mineralized ground will find the HF2 invaluable. While it won’t replace a dedicated PI machine for extreme depths, it’s excellent for working bedrock cracks and shallow deposits.
Coin shooters who frequent parks, schoolyards, and sports fields where micro-jewelry and small denomination coins get lost will recover targets others miss.
Practical Tips for Getting the Most from Your HF2
Start with the factory settings, then gradually increase sensitivity until you experience instability. The HF2 can run hot, but stability trumps raw sensitivity every time. You’ll recover more targets by maintaining a consistent threshold than by pushing for maximum depth and dealing with chatter.
Use the Iron Volume feature generously. With the HF2’s enhanced sensitivity, you’ll hear more iron grunts and falsing. Setting iron volume to around 3-5 helps you focus on the good targets while still getting iron feedback.
Consider using the Fast program or creating a custom program with recovery speed set to maximum. The HF2’s smaller size means you can run faster recovery speeds without sacrificing depth on good targets.
Ground balance becomes even more critical with high-frequency coils. Take the extra time to properly ground balance, especially in mineralized soil. The HF2 will reward your patience with cleaner audio and better target separation.
Weight and Balance Considerations
At just 200 grams, the HF2 adds minimal weight to your setup. But, the smaller size does change the balance characteristics of your Deus II. Some users prefer the stock coil protector for added weight and protection, while others appreciate the lighter feel.
If you’re doing extended detecting sessions, consider how the weight distribution feels with your chosen shaft configuration. The HF2 works excellently with both the standard and remote control configurations, but you might need to adjust your arm cuff position for optimal comfort.
Battery Life and Performance
The HF2’s higher operating frequency does impact battery consumption. Expect roughly 20-25% shorter runtime compared to using larger coils. This isn’t a deal-breaker – just factor it into your detecting plans and carry a spare battery or power bank for all-day sessions.
Weather and Environmental Factors
The HF2 is fully waterproof to 20 meters, making it suitable for shallow water detecting. But, high-frequency performance can be affected by saltwater conditions. In beach detecting, you’ll want to reduce sensitivity and potentially use a lower frequency program if you experience excessive chatter.
Cold weather can also affect high-frequency coil performance. In freezing conditions, you might notice reduced sensitivity or increased falsing. This is normal behavior for high-frequency coils and doesn’t indicate a problem with your equipment.
Comparing to Other Deus II Coils
The HF2 fills a specific niche that the stock coils don’t address as effectively. While the 11-inch coil offers excellent all-around performance and the 9-inch coil provides good balance between coverage and sensitivity, neither matches the HF2’s performance on tiny targets.
Think of it this way: if your Deus II is a Swiss Army knife, the HF2 is the precision tweezers. You don’t use tweezers for everything, but when you need them, nothing else will do.
Is the HF2 Worth the Investment?
At around $200-250, the HF2 represents a significant investment. But, if your detecting focuses on finding small targets, the coil will pay for itself through additional recoveries. I’ve found several gold items and numerous small artifacts with the HF2 that I’m confident I would have missed with larger coils.
For casual detectorists who primarily hunt coins and larger relics, the HF2 might be overkill. But if you’re passionate about recovering every possible target, especially the tiny ones that others leave behind, this coil belongs in your arsenal.
Final Thoughts
The XP Deus II HF2 coil isn’t just an accessory – it’s a specialized tool that expands what’s possible with your detector. It won’t replace your larger coils for general searching, but it will open up new detecting opportunities and help you recover targets that were previously undetectable.
Whether you’re chasing gold, hunting micro-relics, or just want to maximize your recovery rate, the HF2 delivers exceptional performance in a compact, well-designed package. Give it a try on your next detecting outing, and you might be surprised at what you’ve been missing.
