GPX 4800 Powerful, Deep Seeking, 3 Detectors-in-One, & Easy To Use! Found More in One Week Than I Found All Last Year!

A recent article by Kevin Hoagland Minelab’s Director of Dealer Developement, made some observations regarding Minelab’s GPX 4800 after hearing almost daily from relic hunters across the country about amazing finds being made, many in areas that were previously hunted out. One new 4800 user who Kevin spoke to said “I am not happy, I am ECSTATIC! I have found more in the last week than I have found in the last year! It is truly like my spot has never been hunted before”. Kevin goes on to say, “relic hunters are seeing finds coming out of the South and East. Areas in Virginia seem to be buzzing about the GPX 4800 as the “must have detector” while we at Kellyco have seen a new interest all across the country from Gold Hunters out west, Relic Hunters in the East and South to Beach Hunters on the east coast, Florida, Texas and California!

Simple to Use

When asked, "After I get the GPX 4800 is it hard to use?" Kevin answered “SIMPLICITY is the word to use!” The new GPX Series of detectors are as simple to use as the manual makes it out to be.

GPX 4800 is a Triple Threat Detector.

Much More Than Just a Gold Detector!
Finds Gold, Rings, Jewelry, Relics, Artifacts, Buried and Lost Treasure.

GPX 4800 Sensitive Smooth
Salt-Coarse(GPX 4800 ONLY)
Great for beach hunting coins, rings, jewelry, and other treasures. Finds large nuggets in salt affected and mineralized ground.
GPX 5000 Enhance
Enhance (Improved)
Runs quietly in most heavily mineralized, variable and "hot rock" infested grounds using a Monoloop coil. It is more sensitive and detects deeper than Sensitive Smooth but can be slightly more affected by severe ground mineralization.
GPX 5000 Normal Mode
Gives great performance on a wide range of soil conditions, and target sizes. It is a good default timing to assess a new area.
GPX 5000 Sensitive Extra
Sensitive Extra
Provides the best signal response on small gold in mild to medium ground mineralization.
GPX 5000 Sharp Mode
Finds a good variety of target sizes in mildly mineralized ground. Similar but more powerful than Normal. It is capable of an improvement in depth, but is also more susceptible to interference and ground noise.
GPX 5000 Coin and Relic
Coin/Relic Detecting
Gives significantly greater depth on medium to large targets in areas with zero to very mild ground mineralization.

GPX 5000 Finds
Guy with GPX 4800 Metal Detectors
GPX 4800 Relic Finds

US field tester "When I first discovered the spot it was easy to dig fifty or more bullets in an afternoon but in time the count had dwindled down to 5 or 6 in an equal amount of time. My trip there with the GPX netted 78 bullets that the other top ranked detectors had missed."

UK field tester "...although this site had been cleared of all targets using the GPX-4000, I still managed to get lots of good strong responses from targets around 10 inches deep."

GPX 4800 Finds Gold Aus. field tester "I counted up all the small gold I have found in this site, so far it is 419 pieces for 210 grams ...and thats in well searched, extreme ground!"
