Deepest and most capable Gold Detector in the world! Minelab is offering a more versatile, easy to use, gold prospecting detector that has more power and performance than ever!
New Features gpx4500 new features Function LCD Display - The most obvious change to the GPX-4000 is the new LCD display on the rear of the control box. Simply scroll through the various functions of the detector and select the level required. All the variable level controls offer precise numeric settings for more accuracy. Now you can compare the effect of different settings precisely and easily remember your preferred levels, without the risk of settings being accidentally changed during transit or while detecting. All setting changes are saved automatically on Shut Down, and loaded up when you switch the detector on, then at anytime you can restore back to the Factory Preset settings. The Minelab Gold Nugget Detector. FEATURES NEW TIMINGS so the GPX4500 is even more versatile. Users of the GPX-4000 have learned just how valuable it is to have a range of timings to optimize the performance of the detector. In addition to the four timings found on the previous model, the GPX4500 now introduces two new timings, Enhance & Sharp. The new Enhance timing is a powerful feature, similar to the Sensitive Smooth timing, but provides an improvement in the depth and signal response on small and larger targets. The Sharp timing is more suited to quieter soils and can also be used for pin-pointing. NO-FUSS DETECTING WITH PRE-PROGRAMMED SEARCH MODES The GPX4500 offers pre-programmed search modes, for easy switch-on & go detecting. In addition to the General and Deep search modes are four others, Hi Mineral; Hi Trash; Patch and Test A modes. All 6 search modes can also be modified with your favorite settings and renamed. GB (Ground Balance) OFF for neutral soils. When searching in non-mineralized soils, ground balance can be switched off to give increased depth. This setting will be popular for treasure and relic hunters in loam or sandy soils. BACKLIGHT so you can read the LCD menu in any light, day or night. The backlight has adjustable time-out to preserve battery life. STABILIZER for the smoother threshold. The Stabilizer function is a fine tuner that gives the operator full control over the threshold stability. After all other functions are set, you will use the Stabilizer to give fine adjustment for a smoother threshold and the ability to pick up the faintest of signals. TARGET VOLUME ... Target Volume allows you to increase the strength of softer target signals. This is useful for very windy conditions; for people suffering from hearing loss; and to adjust the audio volume when using external speakers. This is a powerful feature, and will work in conjunction with the Stabilizer control, giving you the ultimate in fine tuning ability. IMPROVED DISCRIMINATION gives you access to the worst of trashy ground. When detecting in a high-trash area like a mining site or a campground, the Iron Reject function allows the operator to set the desired level of discrimination, from cautious to aggressive. This will assist detecting in areas that have previously been rejected due to the quantity of Ferrous junk. BUILT - IN AMPLIFIER allows you to hear soft target signals from deeper nuggets, more easily. The newly designed Li-Ion battery pack now has an audio amplifier built in, which boosts target signals, if using an external amplifier. The design of the amplifier and the use of high-quality low noise components ensure the signal response is clear and crisp, without the added background hum of some boosters. SETA Explained The GPX4500  by Minelab Detectors for Gold Prospecting now offers a total of six Timing options to suit different detecting conditions. Previous GP series detectors operated using one universal alignment suitable to all their timings. With so many different timing options packed into the GPX4500, it was no longer possible to rely on a single alignment, and so the Smart Electronic Timing Alignment or SETA concept was born. SETA automatically sets a precise alignment for each Timing option. What this means is that in each timing, noises caused by magnetic interference will be minimized, the threshold will remain more stable, and signals from highly magnetic rocks will be significantly reduced. This allows you to harness all the power of the GPX4500, and operate it more efficiently under different conditions. SETA technology allows each timing to operate independently and much more efficiently so that deep and small hard to hear nuggets become more obvious	GPX-4500 by Minelab Metal Detectors
Pre-Set Search Modes - Patch Finding, General & Deep Detecting - Different search techniques require different settings on your detector to give maximum performance for best results. If out patch finding over virgin ground your priority is to cover more ground at a faster sweep speed, you need a detector with fast target response, sharp clear signal and possibly fast ground tracking. However, carefully chaining an area that has already produced nuggets requires an entirely different set of settings. The GPX-4000 offers three pre-programmed search modes already set up for the three common search techniques - Patch finding; General detecting and Deep slow careful detecting. As you get more familiar with all the new functions of the GPX-4000, you can then program your own preferred settings for each technique, or search mode. The GP series including the 4000 are amazing for gold prospecting.

Functions

• Gain - The Gain function sets the overall performance level of your detector. In areas where the search conditions are mild, you can increase the Gain, and in areas that are more difficult it can be reduced. You'll find using the Gain control in combination with other controls like Timings, Audio and Ground Balance will enhance performance to the ultimate.
• Sensitive / Smooth Timing - The GPX-4000 now has two sensitive options. The all-new Smooth option dramatically reduces signals from hot rocks and false ground noises, yet remains highly responsive to small targets. In mild ground conditions, the Sensitive Timing found on previous GP4000 detectors, now called Extra, is the preferred option as it will provide greater depth.
• Ground Balance Type - In addition to the normal ground balance that we are all familiar with, the GPX-4000 now has an optional "Specific" ground balance, designed specifically for use in very hot ground and especially useful with Mono-loop coils.
• Response - We are all familiar with the standard distinctive target signal we get from small nuggets, it tends to start with a rising tone and then drops to a lower tone. Because we usually find more small nuggets than large ones, this target signal is very familiar to us. The response function allows you to invert the normal target response so that when you're detecting deep ground for large nuggets, the target response from a big nugget is easier to hear, as it will be the familiar target signal you're used to hearing.
• Motion - Different sweep speeds demand different software so that the detector can give the best results. The Motion function allows the operator to indicate their intended sweep speed to provide the best threshold stability and target response for that sweep speed.
• Volume Limit - Improvements have been made to allow potentially loud signals to be reduced without any loss of signal strength on weak soft signals, even on very low settings.
• This Gold Nugget Detectors is one of the finest for Gold Prospecting.

New Lithium Ion Battery

For a mere 870g, Minelab's new lightweight Lithium-Ion Batteries hold their charge at almost full power for hours more than conventional batteries and will operate the GPX-4000 for over 12 hours. The intelligent charging system is self-contained in the robust yet lightweight aluminium housing, offering very rapid recharge times of 3 to 4 hours, from either the 12v vehicle or Mains adaptor. Best of all, the available power of the battery can be tested at any time through the LCD display on the detector.

New Padded Comforter Belt

Included with the GPX-4000 is a new padded waist belt that makes wearing the battery harness all the more comfortable, you won't notice you have it on.
