I was looking at the photo a bit screwie eyed and then realised you took the Multi Kruzer and put a Racer coil on it haha, nice job anyway. 

Yes I did a similar thing to you Steve, realised I had way too many detectors, so the Impact replaced the Racer 2 and Gold+, and the AU Gold Finder replaced the Gold Racer. But instead of getting rid of everything as a retailer I still need demo units, and my son is rapidly growing up 

Knobs and switches of the Gold Finder is what won me over the Gold Racer, so not sure if the Gold Kruzer will pip first place, but that Micro mode has me intrigued... 

I sell both and have used both. Here's a few points of difference. 

• 705 can be run on different frequencies (with different coils), the Fors Gold+ is locked on 19kHz
• FG+ has an adjustable iSat, the 705 doesn't
• FG+ has a search/night light, the 705 doesn't
• All the FG+ coils are waterproof. The 705 10x5" elliptical and 10.5" round are not, but the others are.
• Both run on 4 x AA's and have great run time
• 705 is a little lighter, but the FG+ is better balanced, particularly with bigger coils
• 705 has target notching ability, FG+ doesn't 
• 705 has a Iron Mask circuit in all-metal mode, whereas the FG+ has an active target ID in its all-metal mode
• Both have very good volume, auto tracking, auto GB/reset/grab, adjustable Audio Tone, Freq shift

Where they differ more is in the Disc modes. The 705 has a single style disc mode, but you can save 4 different "patterns" or levels of discrimination. The Disc mode is a beep mode, and does have various tone options, 4-tone, multi etc. This is what most coin hunters want. 

The FG+ has two different Disc modes Fast & Boost, but both of them are VCO or modulated audio. Both are two-tone modes, i.e. low tone for ferrous, and high tone for non-ferrous, but targets get higher in pitch the bigger/closer they are. This is generally the type of Disc mode preferred by Relic hunters, but I love the modulated audio for searching for shallow modern coins in certain areas, as I can ignore the deeper mellower responses. 

So basically, the 705 gives you more versatility to hunt for coins, especially with 7.5 kHz coil options, and notching.

The Fors Gold+ is more a gold/relic hunter, and for those who like to hunt more so by audio. 

Difficult, General, Patch Locate should handle most mineralised/salty ground with ease. Before the addition of Patch in the latest software update, I only ever encountered 3 spots of extreme mineralisation where I had to use Extra Deep & Difficult, and still found gold. You do lose a fair amount of sensitivity in Extra Deep, but I like to think that the reason I got gold there was that previous machines really struggled in that soil. 

Hi all, 

Merry Christmas! 

Here's a couple links over on Prospecting Australia where you can read some comments / feedback:

I tried the Ultimate on the Sovereign and it was an improvement on the stock coil no doubt and very light, but then I tried the 14x10 and it is even better! 

Good news! Now hopefully they'll expand to other coil styles, and maybe do a 14x10 excelerator for the Impact!

Actually just found this video test between a GPZ and GPX on an undug target using larger coils.

 Hopefully Nenad does not mind me posting his test here on this forum and subject.

There appears to be very little difference between both the GPX and GPZ on this target.

Share away no probs. 

The big difference is that the GPZ in Normal with a slightly lower sensitivity could easily be run in that ground. The GPX would need the Sensitivity dropped to minimum, and you'd need to have good tolerance to noise. If I had a time machine, I would love to go back and try a big DD on the GPX.

“Sharp is similar to Normal but creates a more powerful detection field. It is capable of an improvement in depth, but is more susceptible to interference and will increase the severity of false signals in difficult grounds. This timing is best used in quiet conditions and can work well in combination with Deep Search Mode with a reduced Rx Gain setting. Sharp is an excellent tool for pinpointing faint signals due to the very "sharp" signal response. Sharp will work best with DD coils in most gold field locations.”

 

Have a guess who wrote that? 

"I will have faith in my gear"
 

This should be no. 2 on the list of 10 Commandments for Electronic Prospectors. 

No. 1 is - I will love doing this even on days when I find no gold 

Well done, the next bits will come a lot easier I think.

The thing I wanted to know was am I wasting my time detecting areas that were known for deep gold as newer detectors aren't really punching any deeper than the older ones, (sd2000) especially the detectors that were made or modified to get around the government emission laws. I think Reg has answered my question.

Of course, there's the chance in those areas nobody got it all, but I think my time is better spent in areas of less attention as I just haven't had much success in the flogged areas running a large coil.

Last week I was in the exact spot that the prototypes found good gold. Detected all around that immediate area for nothing. Got me thinking maybe there's no gold left, maybe my detecting skills are poor or maybe this gpz4500 just doesn't go as deep as their detectors did. When you don't have years of experience under your belt all you can do is ask, hence the reason for the original post. 

Jin, it can be a bit of a combination of factors which vary between spots. 

The 4500 is well up to the task to find big deep lumps, it's just that people don't really set them up to target big gold. 

In milder/medium mineralisation I'd be using the biggest DD you can get your hands on and Sharp timing.

In hotter soils I'd be using Enhance and a big mono, 19" Evo or 20" NFA or 22" Gold Stalker. 

Yeah the old concentric coil on the GM's were prone to becoming very touch sensitive. I rebuilt mine and it ran a lot better. Anyone buying a really old one would probably want a new coil for it. For me personally, out of the Whites I'd go a V/sat or a GM3 over a GMT.

Are these MarsMD coils any good?

My Impact stock coil cable failed on me this week which is very disappointing when the cable is protected in the shaft. I think it's been like that for a while because the machine would go silent and then come back. 

It's still a brilliant machine and I wouldn't swap it for anything but I need the coil replacing.  

Make sure the cable connection inside the shaft is nice and snug. Mine lost audio, then I noticed Check Coil message on the screen. Tighten up the connection and all good. 

So looks like maybe no Mosca for a while.

But this interests me a lot more:

Do they mean a gold coloured F75 or an F75 Gold operating on 71 kHz 

Don't know about the F75 but on the Makro Gold Racer and Nokta Gold Finder comparing 5" to the 7.5x4", the elliptical has a sharper response, a clear depth improvement (although small), but bangs a bit harder on hot rocks. 

Yeah exactly. Also for me, small coil equals less EMI, equals greater sensitivity levels and/or less Smoothing required

Funny how all the manufacturers are now starting to use the same dramatic music, teaser videos, your old product will be redundant etc etc. 

They're the exact 4 controls I'd want on a v2 SDC2300  ....and maybe tone as well.

I think the Eldorado's were about 8 kHz, same as the Goldseekers. 

You can still download the Goldseekers manual here: http://www.minelab.com/__files/f/4108/Inst Manual Goldseeker 15000 Website.pdf

Always interested to read your opinions on this Steve, so thanks for keeping it updated. As far as I know the GPX4800 has been discontinued. http://www.minelab.com/customer-care/product-notices/discontinued-products/gpx-4800

Also, any reason why the Au Gold Finder isn't on the list? It's about as dedicated prospecting machine as they come. It's like a modern day hybrid of the Gold Bug 2 and Gold Racer. 

RRP in oz $1299

Thanks Steve, have you seen the weights of these coils anywhere? 

Not sure why they'd do the sniper, it is virtually identical to the Nokta 9x5". 

I wish someone would do a 9" round in a solid version for rocky terrains, but seems spoked coils are all the rage these days. 

I do use pin-pointers when it is a deep target, particularly in hard ground, where you really don't want to open it up too much. Saves a tonne of time! 

Pin-pointers simply don't have the sensitivity to small targets like a gold detector does, so trying to find a tiny target with a pin-pointer is pretty tricky. Much quicker using a scoop. 

I would think they are talking about the SDC2300, i.e. it's an old article that is being recycled, as it says Minelab are at Torrensville, which they haven't been now for some years. 

Detech's largest flat/spiral wound mono is a 14". There is an 18" round and 18" elliptical in the product line-up but these are both a traditional wound coil. I haven't used both side by side, but I'd say the 18' Elite would have more sensitivity to small gold, but the Detech would likely run quieter in high mineralisation (due to less near-coil sensitivity). 

Detech have a new 15" round coming out which will be interesting to see how it compares to the current 14" Ultra, as well as the 15" Evo which is a brilliant coil.  

Here's some Gold Racer gold:
