    Is there such thing

    Oh and to further this, his phone still rings right? Well most phones last about 1 to 2 days tops without recharge, so he is obviously still maintaining his phone, alive and well, near electricity, but not close enough! Try ringing him from another phone/public phone but make sure there is a...

    Is there such thing

    Hey Next1m8, Sorry to hear of your current troubles. For me there are several things that have my alarm bells ringing. Not returning calls or messages. Not turning up to work for 3 weeks. His GF blocking you on FB <<< This is the biggest alarm bell. If all is well, then why has she blocked you...

    Minelab SD2100 tips, settings, questions

    The ground balance control is a 10 turn potentiometer and yes it should stop when it gets to either extreme. If needed they can still be purchased and replaced, though I don't know if Minelab would be willing to do the repair. AuMan

    GPX 4500 with B Z Boster test

    Thanks Nenad and Golddigg@, I think this explains it in this case. The one you have used is very flat and has a good surface area, whereas the ones I have are very round little balls. Might have to deface one and see if that makes an improvement. I guess my expectations might have been too high...

    GPX 4500 with B Z Boster test

    Thanks guys, I had it running in fine gold, gain up about 18, stabiliser around 6, deep, threshold just on edge, fixed. Search mode does not matter, as this just saves the settings you set in it such as tone and a few other settings. It should be labelled saved settings, 1, 2 & 3. Volume set so...

    GPX 4500 with B Z Boster test

    Hi Golddigg@, Just wondering what timing, gain etc you are using in your tests. Would be interested to know as I can't get my 5k to pick up a 0.03 bit at all with either the 11" mono or NF sadie. It has me a bit puzzled. I'd be holding on to that 4500 if I were you! Cheers! AuMan

    3.8oz GPZ Find

    Excellent find Jay! The reason for the funny sounding response to me sounds like the nugget was picked up with a good response in more than 1 channel. Notice as you first swing toward it you start getting a rising response which then quickly swaps to a dropping response as the signal amplitude...

    Best Coil for an F1A/ GP 3500 in WA

    Don't know about them, never tried one and it is not high on my priority list. Nuggetfinder is my first choice for coils, they will bolt straight up to a standard f1 lower stem, but make sure you use some sort of a spacer to go between the coil ears so it tightens up properly and doesn't just...

    MINELAB F1A4 ex military metal detectors - tips, settings, questions

    HI P924, In the absolute most power hungry settings(Big, large, 8.4v) The detector should run for around 8 hrs. However you will probably find that the big timing is better in STD or small for more average sized nuggets. Running in Fine, Tiny the battery should last around 24hrs. There will be...

    3500 v F1A4 Jack Lange stage 2

    HI Daz, After going for a good detect over the Easter break, I can say that it(level 3) is certainly more sensitive to tiddlers than the 5000. I spent about 70% of my detecting time with the 5k, 11" mono, gain about 16~18, stabilizer 7~8, deep audio, fine gold and found 1 nugget about .2g. I...

    MINELAB F1A4 ex military metal detectors - tips, settings, questions

    Kman, This one makes for a very versatile machine, you can set up for small gold and go find it, or set up for bigger chunks. Also having done away with the battery carrier, you get rid of about 750g(with batteries) and don't have to worry about what happens if the battery carrier dies one day...

    MINELAB F1A4 ex military metal detectors - tips, settings, questions

    Hi Guys, The level 3 detector has the following feature list: Tone, threshold, volume and a new gain control allowing much more gain. Has 4 timings, the extra timing being the power hungry timing. 5 frequency selections 2 lower than standard for better depth with bigger coils and 2 higher than...

    3500 v F1A4 Jack Lange stage 2

    G'day John, Well if you are using a small coil, the best setting to have it on for finding small gold that the gpx's have missed(and won't even see) is the "fine" timing and "tiny" on the frequency switch. Start out with the gain at the fp setting and get a gauge for the ground conditions. In...

    Best Coil for an F1A/ GP 3500 in WA

    There were a few cheapies floating around on ebay a few weeks ago, but it seems now that everything has gone back to the normal prices. Good luck! AuMan

    Best Coil for an F1A/ GP 3500 in WA

    Round coil for sure! The reason they are better it when a target is at the extreme of the coils depth, the response is received by the whole coil. The target has to be in the centre of the coil. With an elliptical, a target at depth will only induce a response into parts of the coil, so a lot of...

    Best Coil for an F1A/ GP 3500 in WA

    Geez, you make it tough! Probably the 14" would be the best all rounder, though you should really get into the habit of changing coils. Deeper ground to the bedrock use a larger coil, shallow ground, use a small coil. AuMan

    3500 v F1A4 Jack Lange stage 2

    Hmmmm, well not quite, to copy it would be to reverse engineer it then from that reverse engineering, produce a "clone". The reverse engineering is purely so I can fully understand every aspect of the circuit and ensure that just about anything can be repaired and make sure that the mods have no...

    Best Coil for an F1A/ GP 3500 in WA

    How long is a piece of string? All coils are good and have a purpose. I quite like the 18" NF coil, still nice and light and goes deeper on those bigger bits that get missed by all those that don't venture beyond the standard 11" coil that came with their detectors. Round coils will always...

    Minelab X-terra 705 General Tips, Advice, Questions

    The headphone plug has contacts on it that need to close to make the speaker work. If you often use headphones, the contacts can loose their springyness and then they don't contact properly when the headphone plug is removed. If your tricky, you can bend them a little to make the contact better...

    Minelab GP3000 tips, settings, questions

    Hey mate, have you checked the power lead? And tried a different pair of headphones? Can you be sure that the camcorder battery is delivering voltage to the machine when it is switched on? Sometimes with these batteries, without load, they may appear to be alright, but when a load is applied the...
