It’s your job to drop tin foil, nails, coins and gold in your yard and play with discrimination. 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. A machine with ground balancing detects what type of ground you’re on, and eliminates the unwanted minerals in response. Using maximum sensitivity means ALL metal signals will ring out, including minerals and trash.
But this round of testing was scheduled during wintertime, which meant we were fighting frozen ground, cold temperatures and snow outside of our lab. In the end, our arms were sore and our fingernails were dirty, but we had a clear understanding of which metal detectors worked and which ones didn’t. Some didn’t have any volume control, which meant we dealt with a lot of beeping and other various screeching noises as we tested each one carefully. The screen is easy to read in all kinds of light and is also quite easy for even the newest of hobbyists to figure out. The large LCD screen uses notches to show how far beneath the surface objects are buried, and this device got it right 46 percent of the time.
The only factors you need to consider here is that you get a fully submersible machine with good discrimination — that’s really it. 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. The type of hunting you plan on doing makes a major difference in what machine you buy.
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.
You’ll want it with you when you’re scanning the beach for treasure. Any gold or silver objects, or groups of coins over 300 years old is classed as ‘treasure’ and must be reported under the Treasure Act 1996. Vistus metal detectors are capable of detecting both ferrous and non-ferrous metals and are specifically designed for the food industry.
Minelab’s new 6 inch coil for the Equinox series is ideal for detecting on difficult terrain and restricted spaces. The Safari is Powered by Minelab’s FBS technology, it combines deep accurate detecting. This detector offers all the features an advanced treasure hunter could want but is easy-to-use recommended you read right out of the box. The GOLD MONSTER 1000 turns beginners into experts with fully automatic operation in an easy-to-use, high performance detector. The Minelab GPX-4500 has cutting edge gold finding technology offering features and performance levels that other manufacturers are yet to match.
Even if you were just caught in a rainstorm rather than a full dunking in the sea, it can destroy the control box. Turn down the sensitivity if its stuck on high, check for nearby power lines, radio stations or another detectorist. Move away accordingly. They range from 3 kHz to 70 kHz with gold detectors in the 13-50 kHz range.
At 55 years of age Lee has been searching for treasure for about 35 years now and said his biggest find was a gold in Western Australia. Minelabs innovative W8 distribution system and specialist features allow you to spend more time in the field, detecting with ease. The waterproof 6″ round Double-D coil is very sensitive to small targets, and perfect for finding treasure in high trash areas. Minelab 11″ round DD Smart Coil for the Minelab CTX 3030.
Extreme depth maximum sensitivity, the GPZ 7000 outperforms all gold detectors on the market. Joan Allen Metal Detectors UK have been supplying metal detectors and metal detecting accessories in the UK since 1968.
You’ll also want to avoid a pulse induction machine — or PI for short. Most machines are designed for coin and jewelry hunting — especially those priced under $600 or so.
