Details on the use of metal detectors to look for archaeological objects and frequently asked questions on what to do with finds. Another thing that you may want to consider when you shop for metal detectors online is the frequency range.
All visitors, patients and employees (whether off or on duty) must pass through the Metal Detectors Hub each and every time they enter the building through the Main Lobby entrance and or Emergency Room entrance. The original T style handle and shaft provide you the best detecting experience.
There’s also a handy depth indicator so you’ll know how far to dig, and the multi-tone audio will let you know what you’ve found without consulting the screen, which is handy in bright daylight. The ACE400 is a solid all-round detector you’ll love to play with. You also get volume control headphones and a cover to protect the non-waterproof control box. Their new Ace 400 detector sits pretty at the top of the beginner range while being solid enough for experienced hunters. The 400 is an upgrade on the excellent ACE 350 which is now discontinued.
However, you need written permission from our Head of Parks and Open Spaces to use metal detectors in any open spaces owned or managed by us.

The AuditCheck function tests and documents detection in an automated process.
The major benefit to PI machines is their superior depth in highly mineralized areas like salt water beaches. Frequency and depth have an inverse relationship, so the higher you get, the less depth you’ll get on coin-sized targets.
As you increase discrimination the machine will ignore other metals like tin foil, can tabs, nails, and coins. Low discrimination means all metal including soil minerals, are picked up. It’s usually a button or dial on the control box that you need to settle on before venturing forth. The machine does the hard work, adjusting itself as you move around.
Another example is when people try to use an entry level detector in areas like the pacific northwest where the soil is extremely mineralized. A perfect example of this is when people say the AT Pro is awesome in salt water. Remember, the ‘right’ detector depends on factors like skill, budget, use, location, etc.
Walking over rough ground is hard work and you’re likely to be out there a while. A pinpointer also means you don’t need to shove a trowel into the ground. Carrying a detector for hours can tire you out before you’re ready to head home. Headphones reduce outside noise from wind, waves, and traffic helping you concentrate on target tones, but in my opinion, the best reason to get headphones is so the general public doesn’t get involved in the search. Dip and drag in through sand and water to grab a target before it drifts out to sea.
Joan Allen Coinshooter Junior Metal Detector with Discrimination and Sensitivity Control. Minelab’s new15 inch coil for the Equinox series is ideal for detecting on large areas where ground coverage and depth are required. The Fisher F44 Metal Detector with 11 x 7″ DD Biaxial coil is the top machine in the latest F Series from Fisher Research Labs. The Whites Surfmaster PI Pro Dual Field metal detector combines turn-on-and-go ease and unbeatable depth and sensitivity.
A pulse induction machine finds deeper, smaller objects than VLF detectors and they’re programmed to ignore ground minerals. If you want to buy only one machine, and intend to hunt on land and dry sands, choose multi-frequency as it will have a better discrimination range. Depending on your machine, it may narrow the search area down to a foot or two.
Modern top models are fully computerized, using integrated circuit technology to allow the user to set sensitivity, discrimination, track speed, threshold volume, notch filters, etc., and hold these parameters in memory for future use. Whether you’re a metal-detecting expert or novice, we keep it simple. And, by the way, my 7 year old son Juanito found a nickel yesterday when he took his detector out for the first time!
