Very high sensitivity will pick up small earrings for example, but also iron particles in the soil. 3 tone audio identification can ping out audio tones set to differing metals, so set gold to high for example and listen for the high pitched tones. The Teknetiks PRO has variable iron discrimination that you can adjust from 0-39, and FEtone which allows you to adjust the tones emitted from targets. Stopping every few feet to dig up iron is what makes or breaks this hobby, so it's important to get yourself a detector that can discriminate well.

However, it is recommended that testing is carried out at the start and end of each shift and of each new product run, and should be clearly documented within standard operating procedures. There are no mandatory guidelines on the frequency of tests, unless these have been identified by a retailer code of practice or by requirements from a customer or external agency.

Most of us here are hobbyists and the Garrett ATX would be overkill for anything we wanted, however, due to the ease of access we had to include it. Lightweight – This product is light enough that even children can use it. It comes with 3 buttons and also 3 different detection modes. Pro mode audio feature – allowing you to change the frequency of the noise is great for anybody that struggles to hear higher pitched sounds.

Still, it makes sense to buy an entry-level machine until you are sure this is the hobby for you. The basics haven't changed over time and taking potluck is all part of the game. This detector may look a bit old fashioned but it does the job better than many of its flashy companions.

It can tell us things like depth of the target, what it thinks the target is, where our sensitivity and discrimination are set, battery life and many other things, depending on the detector. One thing you want to make sure of here is that you do not buy a machine with too high frequency – i.e., one designed for gold prospecting (you can read our guide here on the best metal detectors for gold nuggets). We are a Certified dealer in all major brands, with over  20+ years experience and many finds, Whether you are looking at Metal detectors for gold nuggets or treasure hunting we are able to direct you with training and the right equipment. When it comes to choosing a detector to help with hunting for gold, one of the better models happens to be the Garrett ATX.

This is what detectorists are talking about when they complain about ground mineralization. Often troughs and pockets in the ground collect a variety of objects. Always fill the search hole cleanly and remove any mess before moving on, but before you Metaldetectorshub carry on your merry way, take a really slow and close sweep of the surrounding area. If you're relic hunting, take a note of the exact place because a historical record is helpful to archaeologists should that relic prove interesting or unusual.

11″ Bi-Axial Search Coil – A very large scanning area will mean less passes and also lowering your chances of missing something. When using this product we were able to figure out what metal we were digging up way before we even decided if it was worth it. Sensitivity – The 400 comes with a higher frequency than the 150, 250 and 350 coming in at 10kHz. Consider the Garrett Ace 400 the bigger brother to the 250, it is more expensive however you get more features and is the natural next step for any avid detector.

Metal detectors are electronic devices that feature a large coil of wire, or transmit coil, and a second coil of wire, the receive coil, that indicate buried metal via a speaker. The more conductive the ground (eg, wet from rain, salty soils, ferruginous soils) the shallower the detection range. A budget detector is capable of alerting you to a gold ring and may end up paying for itself, but only if you can understand what it's saying to you. This is not an easy task, and if you don't go where gold is known it's nigh on impossible. In this case, you'll need a fully waterproof detector with excellent ground balancing because black sand is highly mineralized, and this can set the detector squealing and popping without a break.
