Enhance Your Treasure Hunting with the UniProbe by DetectorPro: A Comprehensive Review
For treasure hunters and metal detectorists, having the right equipment is essential for success in the field. Experienced detectorists, metal detection specialists (like Ring Finders), treasure hunters, and gold prospectors know that not every hunt or terrain is suitable for a conventional metal detector or pinpointer. Crevices, cliffs, and steep hills can make it difficult—or even impossible—to maneuver a standard detector, even with a small coil.
Fortunately, there’s a solution that enhances any detectorist’s toolkit: the UniProbe by DetectorPro—a pulse induction probe integrated with high-quality headphones.
Versatile Compatibility: The UniProbe can be used as a stand-alone probe or connected to most major metal detectors with a ¼” headphone plug. It is also compatible with specific adapter cords for:
- Garrett AT Series
- Minelab Equinox Series
- Minelab CTX 3030
- Minelab Manticore
- Nokta Detectors
- XP Deus I/II
Audio Switching for Between Detector and Probe: When connected to your metal detector, the UniProbe enables audio switching between your detector and probe—no buttons to press, no activation delay, and no need to adjust your headphones. Simply flip the toggle switch on your headset to switch seamlessly between your detector and probe.
Doubles as a Handheld Pinpointer: Using the UniProbe eliminates the need for a separate handheld pinpointer. Personally, I secure the UniProbe by tucking it into my belt loop, attaching it to my belt, or placing it in my finds pouch for quick and easy access.
Privacy and Enhanced Focus with Headphones The built-in headphones keep the probe’s audio signals private, ensuring a distraction-free experience. The direct signal transmission allows for isolated listening, effectively blocking out wind, traffic, and other ambient noise. This feature makes it easier to hear faint signals, which is especially helpful when detecting small targets such as gold stud earrings or fine gold small nuggets.
Traditional pinpointers that use open-air audio project sound into the environment, leading to potential interference and privacy issues. The UniProbe’s headphone-based system ensures clarity, focus, and less missed signals in noisy conditions.
Durable Probe Tip: Most handheld pinpointers eventually wear out due to their plastic composite tips. The UniProbe features a more rugged construction, making the probe tip more durable and resistant to wear during prolonged use.
Key Features of the DetectorPro UniProbe
Dual Functionality: The UniProbe combines the roles of a metal detector probe and a pinpointer. With integrated headphones and compatibility with most detectors, it offers seamless transitioning between locating and pinpointing.
Pulse Induction Technology: Built with pulse induction (PI) technology, the UniProbe provides impressive depth and sensitivity. PI detectors excel in mineralized soil, making the UniProbe ideal for tough environments like gold prospecting areas.
Built-in High-Quality Headphones: The high-quality headphones deliver crisp, isolated audio. They’re designed for comfort, supporting long detecting sessions while minimizing distractions from external noise.
Adjustable Sensitivity: The sensitivity can be adjusted, allowing users to fine-tune the UniProbe for maximum performance in varied soil conditions.
Water-Resistant Design: While not fully submersible, the probe and cable are water-resistant and safe for use in damp environments or light rain. However, the headphones are not waterproof and should be kept dry.
Lightweight and Portable Compact and easy to carry, the UniProbe is perfect for detectorists who travel light or explore difficult terrain. It fits easily in backpacks or can be clipped to a belt.
Who Should Use the UniProbe? The UniProbe is ideal for any detectorist, archeologist, metal detection service providers looking for improved precision and depth. Its pulse induction capabilities make it especially effective in mineralized soils, while the dual functionality and built-in headphones cater to both hobbyists and professionals.
Using the UniProbe as a Stand-Alone Detector I particularly enjoy using the UniProbe on its own in environments like tailing piles and rock crevices. Its narrow profile outperforms standard pinpointers in confined areas, especially when working around vegetation, rocks, or archaeological features.
Waterproofing Details The probe and cable are waterproof and suitable for freshwater and saltwater use. However, the headphones are not waterproof and must remain dry during wet weather or underwater use.
Power Source Powered by a standard 9-volt alkaline battery, the Uni Probe provides up to 6 hours of continuous use. The battery is conveniently housed in the non-control earcup, making it easy to access using a coin and replace. During testing, the battery proved to have impressive longevity, with a new 9-volt alkaline battery providing up to 6 hours of continuous use.
My Experience with the UniProbe: I find the UniProbe particularly effective as a stand-alone detector. It offers a lightweight alternative to swinging a full-sized detector, which is especially valuable when exploring remote or rugged terrain. In Southern California’s intense summer heat, its compact size and portability are a significant advantage. There are times I only take the Uni Probe and leave my full size metal detector at home because of how convenient it is.
On my first outing with the UniProbe, I located a small rivet within minutes while scanning tailing piles at an archaeological dig site that had already been searched with conventional detectors and sifted by hand. The UniProbe helped me recover several small artifacts that had been missed by both detectors and sifters.
During another hunt, I used the UniProbe to explore around a large Beavertail Pricklypear Cactus at a late 1800s to early 1900s dump site. A traditional detector couldn’t be swung safely or effectively in that space, but the UniProbe allowed me to search thoroughly without damaging the cactus or injuring myself. Its slim design lets it access narrow crevices that are too tight for standard pinpointers.
I’ve also used the UniProbe with both the Minelab Manticore and the Nokta Legend, keeping it tucked in my belt or finds pouch for convenience. It connects via the headphone port securely.
Pros:
- Combines pinpointer and probe functionality
- Good depth and sensitivity via PI technology
- Quality, built headphones
- Adjustable sensitivity for different environments
- Compact, lightweight, and highly portable
- Excellent getting into tight spaces, where a conventional metal detector can’t fit
- Due to it being PI technology, it works great in highly mineralized soil
Cons:
- Headphones are not waterproof
- Slightly more complex than standard pinpointers
Distinguishing Old vs. New Versions
Identifying the version is easy: older models feature off-white headphones labeled “UniProbe Detector Probe,” while newer versions come with black headphones labeled “Grey Ghost.” See an example of the older model HERE on Friendly Metal Detecting Forum
DetectorPro Customer Support
DetectorPro deserves an A+ for their customer service. Before a trip, I lent the UniProbe to a gold prospector, I wanted them to test it for this article in the gold field. Being curious, they opened the connector where the probe connects to the headphones, and found a white wire that wasn’t connected to anything. Worried and embarrassed they had damaged the unit, they wanting to fix it before they use it or return it, and contacted DetectorPro when they couldn’t find the answer elsewhere online . The DetectorPro responded quickly, assuring them the white wire was intentionally unused. Their fast, professional, and helpful support stood out.
Since both he and I noticed that others had the same question in metal detecting forums, I decided to include this clarification in the review—for anyone else wondering about the purpose of the white wire. See the email to support and response below.
