Advice for a newbie with a gpx5000
« on: October 15, 2016, 20:16 »
G'day guys, most of you know I am not new to detecting but I am new to the gpx5000. I have been keeping an eye on the prices and working weekends waiting to get enough to buy one of these. 5 hour round trip to pick it up and 1 hour round trip to test it out in the bush. I literally know nothing about coils, settings ect so any general advice or info would be greatly appreciated. It was less than $4500 and came with two batteries so I figured it was a gold deal. I'm used to the ATX so this is pretty different. What do you blokes reckon would be the best coil to run around over the patch I found with the ATX?



  • Detector(s) owned/used: Minelab sd2100 (used). I own minelab GT16000, GPX5000, garrett ATX, garrett AT pro, lesche digging tool, garrett pin pointer.
  • Oldest find: Gold, 1906 dog tag, 1866 English penny, 1733 farthing
Don't gain the world and lose your soul, wisdom is better than silver or gold....

2015 gold rings : 22
2016 gold rings : 15
2017 gold total between my mate and myself : over 2000 nuggets, approx 50 species for a total of Approx 20 oz over 9 weeks prospecting.

I reckon I'd give them all a go, best way to learn your new machine.
Be good to have the ATX there as well when you're testing, see how both machines react to the same target?

You really need to determine how deep it is to bedrock. Once you have an idea of tne max depth, then you can choose the most appropriate coil. As a rule of thumb, use the coil with the diameter closest to ground depth.  This will give you the best chace to find the larger deeper nuggets however if the coil is too large, you will miss the smaller nuggets that a small coil will pick up near the surface.

Nowdays you can throw away most of the old style coils. Rare to see anyone using them around the Vic goldfields. I think you have a 14" elite on show which would be ok if you prefer larger coils. A lot of our gold propecting club members are using the 11" coilteck or the 12" nugget finder. They are far better in finding targets and far worse in pinpointing small finds when you get them out of the ground. 3 internal coils make it a bit trickier to work out where the find is. Don't dig the small targets straight away, spend some time trying settings such as tone and target volumes.

Good score Shane
I've had mine for 4 years , just need more time  to use it ....!
Have a swing using factory settings & if you have some various sized Nuggets , take them out with you
& bury at different depths .
     
     The small Sadie coil will pick up tiny targets in all areas , even flogged .
Rwork is right , the 14" camo coil has the new windings based on the 7000 coil & has good ground coverage .

Thanks for the replies fellas, all advice will be taken on board. Jm94 it would be nice to compare machines but I can't be lugging two detectors around haha. Bicter I have found nuggets in the area but haven't hit bedrock yet so I guess the ground is pretty deep though the deepest nugget was 3.5 grams at about 20cm. Thanks rwork I will play with the settings when I locate a target and see what responds better. Ant I will get out Saturday and run with the Sadie for half the day then switch over to the 14" elite. Very helpful information. Thanks heaps

Well yesterday arvo a bloke heard I didn't know how to use it so he came and explained everything to me. I must have learnt three years worth of experience in two hours!! It was handy that he was an electrician so not only did he explain the settings and what they do but he also explained why. Well I catch onto things pretty quickly and I have come to realize it really is a simple machine!! I have great confidence in picking up a piece or two this weekend on some old well flogged ground

Once you set it to your likings you don't need to be adjusting it often. Don't over do the gain as it can lead to signals like burnt tree roots and hot clayballs. If there are any phone lines in the area you will need to adjust the manuel tune. The front button takes too long. Every time you get it out of the car make sure you haven't bumped a switch. The Cancell button can be a real killjoy. If you get a rubber eraser and drill a small hole in it. Cut it to length across the frame and push it over the switch. This will stop it being selected accidentally. Make sure the coil can pivot easily without pulling on the coil lead.
