Creation worth its weight in Gold!

The GPX-4500 is the ultimate gold finding detector with the new added features that makes it stronger and more versatile than ever before.

Incorporating new SETA technology, it is quieter and more immune to interference, so that it is a real pleasure to use.

No matter if you've never picked up a detector before, the GPX-4500 has automatic functions and pre-set Search Modes that make you an expert in a matters of moments. Quieter threshold, louder target signals, improved discrimination, and more versatile, the GPX-4500 is the gold detector that gives the best results.

New GPX-4500 Features

NEW TIMINGS so the GPX-4500 is even more
versatile. Users of the GPX-4000 have learnt just how valuable it is to have a range of timings
available, to optimise the performance of the detector in various conditions. The GPX-4500 introduces two new timings, Enhance & Sharp, in addition to the four found on the previous model. 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 large targets alike.

The Sharp timing is more suited to the quieter soils and provides the most powerful detection field of all the Soil/Timing options. The Sharp timing can also be used as an aid to pin-pointing faint signals. Increase in Audio Gain. The design of the amplifier and the use of the high-quality low noise components ensure the signal response is clear and crisp, without the added background hum of some boosters.

NO-FUSS DETECTING WITH PRE-PROGRAMMED SEARCH MODES

The GPX-4500 offers a number of pre-programmed search models which allows you to start detecting right away! In addition to the General and Deep search modes is the Custom mode, which gives you access to four other search modes specially selected for specific techniques. These are Hi Mineral; Hi Trash; Patch and Test A modes. All 6 search modes can be modified with your favourite settings, and the Custom modes allow you to select your own mode name.

New Functions

GB OFF for neutral soils.
In addition to Normal and Specific ground balance options, a third option is now available. In GB Off the ground balance circuit is by-passed to give extra deep detection. This is a useful feature in very benign low mineralised, or salt saturated soils. This setting will also work well for treasure or 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 smoothers threshold.
The stabilizer function is a fine tuner that gives the operator full control over the threshold stability. It is tied in with the audio processing circuit, so should be used in conjunction with the four Audio Type options. In quiet conditions, increase the Stabilizer control and faint target signals will be more obvious. Turing it down will provide you with a smoother threshold, improving your ability to pick up the faintest of signals.

TARGET VOLUME
In addition to the Volume Limit control, which prevents signals from being too loud, the new 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. The Target Volume can also be used as an audio boost in mild soils, and can be used to reduce or smooth out ground noise signals in highly mineralised soils. This is a powerful feature, and will work in conjunction with the Stabilizer control, giving you the ultimate in fine tuning ability.

IMPROVED DISCRIMINATION that 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 combined with the specially programmed Hi Trash search mode makes areas of extreme junk well worth a search. Also great for the specialist Relic and Jewellery hunter who demands the best, and wants to recover the smallest and deepest targets invisible to most treasure detectors.

BUILT-IN AMPLIFIER so you can hear soft target signals from deeper nuggets, more easily.The newly designed Li-lon battery pack now has an audio amplifier built in, allowing you to use an external speaker, without the need for any external booster. Its uses smart circuitry, which automatically senses a correctly wired speaker, and applies an increase in Audio Gain. 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 Technology gives precision timings

The GPX-4500 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 GPX-4500, 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 minimised, 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 GPX-4500, and operate it more efficiently under different conditions.

A bonus of SETA technology is that the ground balance setting of each timing is also saved, so if you are switching between timings when investigating a suspected target signal, you wont have to continually re-ground balance the detector.

New Lithium-Ion Battery

For a mere 768g, Minelab's newest lightweight Lithium-Ion Batteries hold their charge at almost full power for hours more than conventional batteries and will operate the GPX-4500 for up to 12 hours. The intelligent charging system is self-contained in the robust yet lightweight aluminium housing, offering very rapid recharge times of 4 to 5 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.

Improved Battery Harness

Included with the GPX-4500 is a new and improved battery harness, now with thicker straps and a reinforced padded belt, for improved support and a more comfortable fit.

Modified Endcaps

The GPX-4500 with Modified Endcaps, now allows for full control box adjustability, to improve balance when using smaller or larger coils.

Heavy Duty Power Cable

Designed to handle the rigours of the goldfields, the GPX-4500 is supplied with a longer power cable, a thicker outer sheath and over-moulded plugs.

Subject: Swingy Thingy

Hello Doc,

One of my hunting partners has a bad/weak elbow, She's been using a lighter machine and always wanted to use my Explorer for long periods of time. Only her bad elbow kept here from using my Explorer.

Today, We hunted the beach and she used my Explorer fitted with the swingy thingy. First time she was able to search for several hours wihout stopping for a rest. Also, First time she dug coins so deep :) Big difference wih using my Explorer and her not so deep light machine.

People can now upgrade to a heavier machine with the use of the Swingy thingy, It makes a big difference.

Thanks Doc,
Paul (Ca)

I have not used the Excellerator coil but I have used the WOT extensively. I was one of the first to drag that coil into the parks where lots of people said you could not use it but you can. I have found a ton of deep coins with the WOT, it locks on silver very hard and is quite sensitive to small items. I found some really tiny silver items and a few half dimes for example. Get DOC's swingy thingy though, without it my shoulder gives out in about 90 minutes. With one you can swing it all day long no problem.

Hey Doc! My Explorer just lost 4 LBS!!

That's one heckuva detector diet plan you're selling there! I received my Swingy Thingy yesterday and thank you for the very speedy ship. My first impression is extremely positive. It's pretty slick that it's quickly and fully adjustable from being a "negative weight" (need a couple ounces downward effort) up to the the operator carrying the full weight of the detector like normal. Very nice! As you probably know our weather has been one storm after another so I haven't been able to really put some serious time into it yet, but early this coming week the weather is supposed to break for several days and I'll get a more involved opinion back to ya then.

For Those of You That Think That The Explorer is Too Heavy... Check This Out!!

Got to try out Doc's swingy thingy today and heres my 2 wheaties worth!!! It is a very simple design and well built. You can tell a detectorist designed and built it. I have really never had any problem swinging the explorer myself but this really takes the load off, I was swinging today with literally 1 finger. The only thing I did notice was it limited the width of my sweep from side to side. You guys that don't like the weight of the explorer Doc's got your prescription!!

Todays results of using the Swingy thingy...Wow!

Hello,

Received my Swingy Thingy yesterday "Harness for Explorer" to lighten/balance and help provide longer hours of detecting. Doc asked for 10 volunteers to use and provide test results of the Swingy thingy harness. I'm one of the ten volunteers and just finished up three straight hours of using the harness. Before I go forward to share my results with the forum, I would like to take the time to say "Thanks Doc" for creating and providing us with a must needed tool "Swingy thingy harness" to help us enjoy our hobby even more. Those of you looking for a tool to help enhance the balance of the Explorer please pay special attention to what I have to share with the forum.

The first feature of the harness that stands out is the quality of fine workmanship put into the harness, Well made and easily sets up for quick use. When I first hooked up the harness, I realized all this time some of us have been taking things off of the Explorer or going to lighter coils to help us detect for long periods of time. Now with the Swingy thingy harness, You can go back to using your larger coils and need not worry about weight being an issue as before.

I've enclosed a couple of pictures of today's test results of using the Swingy thingy, The first photo is a self-pic wearing the comfortable harness while the second pic shows a close-up shot of the bungee cord attached to my Explorer upper shaft running under my meter housing up to my chest/shoulder harness. For those of you already using the harness or intend to add one to the Explorer please take note of how the bungee cord runs below my meter housing connecting to the upper shaft, This set-up allows you to have an even swing throughout the full motion of the swing. The coil and the Explorer feels like it's gliding on air with your hand used only to control the motion of the swing. If the bungee cord is placed against the outer meter housing the swing will not be equally smooth throughout the swing due to drag from pressure on the outer swing.

I can see how the Swingy Thingy will work well for those of you that beach hunt with larger coils for long periods or those of you wanting to go back to using the larger coils, With using the Swingy Thingy harness weight is not an issue anymore.

Thanks for taking the time to review my report.
HH, Paul (Cs)

First day out with Doc's Swingy Thingy!!!!

Today I had the pleasure of using the Swingy Thingy at a grass covered park and I have to say that it is one of the best after market accessories for the Explorer since the x-1 probe.

I found it was much easier to attach the clip to the back of my utility belt before putting the belt on. Once I had the harness all hooked up, I did some experimenting with adjusting the tension on the bungee. If I held my ExII in my normal hunting position and adjusted the bungee to just let the coil touch the ground without having to push the detector down, I could swing it effortlessly.

Some of the benefits that I already have found are:

1.I can concentrate on finding targets for longer periods without having to take breaks to rest my arm.

2. In heavier grass it seems to slide right over it instead of being dragged thru it.

3. When I want to take a closer look at something I just dug,I have to put on my glasses, and that means I have to use two hands. Before the Swingy Thingy, I would lean the detector against my hip to free my other hand, but once in awhile the detector would slip off and fall to the ground ripping off my headphones at the same time. Now I can take my hand off the detector and it stays at my side just like a well trained dog !

Tomorrow I will go to the beach to give the Swingy Thingy a test run with the Wot. I could never use the Wot for more than an hour before switching back to a smaller loop.

Doc's Swingy Thingy... Used it for a couple hours yesterday...

I strapped it on and after a while figured out what needed to be adjusted and got to where I was happy with it. Make sure you get the (right handers) strap on the left side of your body snug enough to keep it on your shoulder. Once you have that exactly where you want it the thing works flawlessly. Definitely a big plus for keep your arm from being worn out.

I only hunt when I can get away from the kiddies and that seems to only be once or twice a month of late and when I get away I try to last the whole day. Just doing that you're asking for trouble with an arm not used to swinging a coil all day.

It works... I will continue to use it and if you find your arm getting sore from your detecting habits you have a fix right here...

Good hunting... Guvner..

Swingy Thingy Review

I finally got out yesterday between rains to use the Swingy Thingy. The load is reduces to almost nothing. This works best on flat ground. I have been using another brand of harness and the response on the Explorer is the same. Because of the bungee system employed, there is stress to swing the machine to the right, then the bungee pulls the machine back to the left. This results in an uneven swing and cramping of the thumb. When trying to pinpoint you must pull the machine to the ground. After using the Swingy Thingy for 4 1/2 hours I unhooked the Swingy Thingy and the Explorer felt like a ton! I could barely move it around.

Negatives: A feeling of loss of control of the Explorer. Employing different muscle groups.

Positives: Much less expensive than systems promoted to reduce "some" of the weight. Almost total weight reduction resulting in many more hours of possible hunt time. Arms of equal size...HA!!!

Thank you for the opportunity to try and review the Swingy Thingy.

I haven't been able to get on line for a about a week and a half due to my computer crashing. Now that I have my new computer up and running I will give the rest of my report and report the finding for the two other guys that don't have computers.

In my first report I stated how great it was using the S.T. for land hunting. This time I took it to the beach and used it with the WOT. I can honestly say that it worked great. I used the WOT for 4 hours and never got tired.

Cliff had a shoulder replacement done on Feb. 14th and went to the beach on several occasions since getting the S.T. and said that he was able to use his ExII for as much as five hours at a time without having to stop and rest his arm. He loves his Swingy Thingy and said that he doesn't have to use a hip mount conversion anymore.

Bob had his shoulder operated on in April and was told by his doctor that his shoulder wouldn't be strong enough to use a metal detector for at least 3 months. He has been going out metal detecting at least 3 times a week since getting his S.T. and the only problem he is having is where the strap goes over his shoulder it is a little tender, so he is going to buy some type of padding to put on his strap.
Doc, we want to thank you for letting us test the Swingy Thingy, and all three of us will not go out metal detecting without it !!!!!!
Thanks Again,

Ed,Cliff,& Bob

I purchased a "swing thing" from Doc. It is a simple accessory designed to make the Explorer or any detector which might be using a larger coil, virtually weightless.

I found it simple to set up and it did exactly as advertised.

It did not get in the way or hamper my digging a hole or detecting in the park or the wood's setting.

I recommend anyone who feels that he/she wants to be able to hunt longer to look into this new product.

Have a great day!

I got back from the bush on Tuesday and one of Doc's bungee cords was waiting for me. Its only had a backyard test so far but it is going to make adjustments while on the move so easy. No more messing around with changing knots in shock cord and still not getting it right. Thanks Doc.

I just received the nifty "Quick Adjust" Bungee that you sent to me Doc, and it works just as good as you said that it would!

I have been using your bungee Doc, and it works just great! I especially like the feature that allows me to make quick adjustments when going up or down a hill!
