Teknetics Delta 4000 - 2 Coil Package Metal Detector

Warranty: Not 2 Years or 3 Years, but a Great 5 Year Warranty!
Why? Because We Make Them Better!

The Teknetics Delta 4000 Metal Detector features a large, crystal clear and easy to read, identification meter. This new design enables even the novice of detectorists to see the treasures they've found before they begin to dig!

Teknetics Gamma 6000 This detector comes brand new, in its original box and with a full manufacturer’s warranty. Purchase includes the ALL NEW Teknetics Delta metal detector, an 8” open-face searchcoil system, and instruction manual.

The Delta metal detector is the latest and greatest from the world-renowned Teknetics metal detector brand. The Delta boasts state-of-the-art detecting features housed in the most modern of detector designs.

The large control housing features push-button controls, numerical depth readout, an intuitive menu system and a running depth indicator. These tools combine to help even the most novice detectorist hunt like a professional! Advanced features include adjustable sensitivity, discrimination by categories, a two-digit numerical target identification system, and two search modes: Discrimination Mode and All Metals Mode.


The Delta transmits a low frequency of 7.8kHz to alert you to literally every type of treasure buried beneath the surface. A pre-set Ground Balancing feature with the bonus of fully static, push-button pinpointing capability will accomplish three things at once.

First: when in the pinpoint mode the detector will automatically center the target.
Second: It will increase the audio tone when you are over the target.
Third: the Delta will indicate the depth from over 0 to over 8 inches.

The Delta comes with a real time “running Depth Indicator” that will show you the depth of all detected targets before you pinpoint.

Two-Digit Numerical Target ID System makes identifying buried target fast and easy! With the Delta, accuracy is improved on all targets and even those older and deeper coins.

There are a total of six discrimination categories that will allow the user to quickly make changes to the factory discrimination patterns. When in the field you simply select the discriminate mode and then use the up or down arrow button to make your change.

Only one 9 Volt battery is required to operate this new, impressive and affordable machine and it won’t just die on you in the field – it features a battery life indicator to make sure you’re prepared to treasure hunt for hours on end!

Very Impressed!

Review by Robert A on May 17, 2013

So...I put together my new Tek 4000, did the bench testing and walked out my front door. Five feet in front of my porch I got a very strong hit showing approximately 8" deep, now what is funny about this, is I had previously MD'd my front yard with three other MD's so I was not expecting to find anything of value, I dug the spot and WOW! a 24K gold Mens 25th Anniversary ring that is engraved on the inside, the date on it Oct 1963. This was the very first thing I dug, excited I kept zig zagging a small area of my front yard and I got another big hit, again 8" down, I dug and pulled a Die cast car made by the Dinky Die cast company in England, this particular car was #243 and was made in the 1950's. review is this thing is awesome, extremely light weight, you can sling this thing around for hours and not get tired from it. the Pin pointer is a little off, mine seems to pin point about a 6" circle area and the Target ID is only accurate 60% of the time, I still dig a lot of trash even when using high discrim modes. But again, this does go deeper than my other previous MD's and with all the bells and whistles this one has, was well worth my money and wait! (that’s another story, but Kellyco made it right!)
