Minelab Excalibur II Metal Detector: The Standard in Underwater Searching and Tactical Demining
In coastal zones, swampy areas and the need for complete immersion under water, conventional detectors lose their effectiveness. Minelab Excalibur II is a legendary underwater metal detector that has remained the standard for professionals for decades. Thanks to unique multi-frequency BBS technology, it effectively works where others are “blinded” by high ground mineralization or salt water.
BBS Technology: 17 Frequencies for Uncompromising Accuracy
The main advantage of Excalibur II is the use of Broad Band Spectrum (BBS) technology. The device simultaneously transmits, receives and analyzes 17 operating frequencies in the range from 1.5 kHz to 25.5 kHz. This allows the detector to automatically ignore false signals from salt water and highly mineralized sand, focusing exclusively on metal objects.
- Depth and stability: The BBS system provides maximum detection depth even for small targets (detonators, fragments).
- Automatic elimination of salt influence: A special mode allows searching in seawater without constantly readjusting the ground balance.
- Tone identification: Different types of metal have different sound responses, which is critical when there is no display in conditions of zero visibility underwater.

Tactical application and operational reliability
Despite its popularity among treasure hunters, the technical potential of Minelab Excalibur II makes it indispensable for special tasks:
- Coastal mine clearance: Effective detection of explosive objects in the surf zone and in shallow water.
- Searching in silted waters: High sensitivity allows you to find Objects hidden under a significant layer of bottom sediment.
- Work in "radio silence": The absence of a display eliminates unmasking glow at night, and the standard headphones ensure the secrecy of sound indication.
Expert opinion: The absence of a display in the Excalibur II is a thoughtful engineering solution. In murky water or during a night dive, you rely solely on your hearing. Mechanical controls allow you to adjust the device "blind" and with tactical gloves, which makes it the ideal tool for a professional.
Why choose the Minelab Excalibur II?
The detector body is made of impact-resistant plastic, resistant to the aggressive effects of sea salt and pressure changes. The discrimination system effectively filters out iron trash, focusing on objects made of non-ferrous metals (gold, copper, brass, special alloys).
Frequently Asked Questions about the Minelab Excalibur II Underwater Metal Detector
Can the Excalibur II be used on land?
Yes, it works effectively on land, but it is heavier than conventional detectors due to its waterproof housing.The lack of a screen requires experience - you must learn to distinguish targets solely by sound (multi-tone indication).
What is the maximum depth it can dive to?
The device is certified for dives up to 20 meters. It is great for both shallow water searching and full-fledged technical diving.
How does it react to salt water?
Thanks to BBS technology, the Excalibur II ignores the electrical conductivity of salt. While other devices "emit" At sea, this detector maintains stability and high detection depth of useful targets.
What headphones are included?
The device comes with built-in Koss underwater headphones. They are non-removable, which ensures maximum reliability and tightness of the system at great depths.
What power does this detector use?
A rechargeable NiMH battery is used. The charge lasts for 14-19 hours of active searching, which covers the needs of even the longest trip.
Does it see small gold chains?
The device is sensitive to small gold, but chains are a difficult target for any detector. The device “picks up” Rings, coins, and other solid jewelry.
This detector maintains stability and high detection depth of useful targets.
