RONS DETECTORS MINELAB

I used to do land boundary survey work and had to go to the county surveyor to look up the most recent plat maps. These maps usually got us in the right places to start looking.
 

Note: On ground markers our what are legally binding unless tampered with.
Don’t count on ONX maps or county google map locations as they can be off a little bit or in some cases I have found them off by a 1/4 mile.

Caltopo map is a good source for looking the area over for mining areas and then seeing the nad 27 topo overlays.

It’s going to be expensive to fix from all the quotes I gotten on board and end cap repairs/replacements. 
 

Since you’re in Oz. You might contact the mod guys there or Minelab’s non warranty service department.

Ebay had some end caps a while back for a decent price.

I have been playing around with the 10x5” DD Commander coil and it seems to have 2 to 3” inches lost in depth versus a 10x5” Coiltek mono on an under four gram target. This was using normal timings with the DD and Fine Gold with the mono.

 I have only done a little testing of it so will need to try some other settings.

This must be Minelab’s way of dealing with the competition, about 30% off of their top multi-freq. detector is quite rare of a sale for sure. 

Manticore $1199 about 30% off plus another 15% military off for those who served for a total of 45% off.

Equinox $999 and also the veterans if you qualify.

Free shipping and Oregon is a no tax state.

Please support your local small dealers as we are going to be going to the wayside pretty soon with most companies going direct sales.

With that being said I will always remember when Gerry, Doc’s and Rob were always the ones to ask technical questions as they usually had the answers.

Thank for sharing Simon, looks like a Winner for sure especially If it can beat the Coiltek 10x5” Joey.

Was this a semi-spiral or bundle wound version?

Now the Algoforce is out it seems like the market is going to be strong for this size coil for sure. I’d buy one right now.

The Sp01 in filter 2 does a good job at clearing up the sounds.

The machine also came with  2 coiltek batteries which are 7 volts from memory and an audio booster. 

If you have the Coiltek li-ion system it takes the voltage down to 7.3 volts for the SD series. Batteries are actually 8.4 volts fully charged.

I also have a 12x6" Semi spiral, this coil is too out of spec to calibrate, works great on the GPX but the Algo won't calibrate with it in its current form,  Algoforce have looked at the coil and established why it won't calibrate and what would need changed with the design for it to do so.  I shouldn't say it doesn't work, it works, it just doesn't calibrate.

If this 12x6” Semi spiral coil has more performance than the Sadie or 12x8” Evo it would be a hit for sure.

It's fun how quickly things get pigeonholed.

My apologies for stereotyping it into only a small gold detector as that’s more dependent on the ground conditions and timings used.

The owner manual says the following:

NOTE: The strength of the E1500 lies in its sensitivity to small nuggets. Therefore, we have only tested the E1500 with small to medium coils. The largest coil we tested is the NF 14”x9” Evo. Although, in theory, larger coils will work with the E1500 without any problem, the shaft could rotate slightly and become wobbly when extra-large and heavy coils are used.

. I was torn between choosing: NF12 evo ? NF14*9 ? NF12*8 ? NF 15” coil

Since this is not a deep large gold detector IMO.

I would recommend using a smaller 9x14” Evo as a good all rounder coil if I owned just one coil, but if I could have two Evo coils for this detector it would be a 12x8” and a 12” Evo.
 

Not sure how the ergonomics would be with a larger coil than these on this detector though, maybe someone with experience with using it can chime in.

Can you buy these Algoforce E1500’s and have them shipped outside of Australia or do you have to have a friend or family member buy it and send it to you?

Northern Nevada does have some of the best specimen’s. This was found north of Rye Patch.

I would return it if you can. They have a high rate of unstableness unless you turn the sensitivity way down. 
 

Here’s a good comparison video though

40 to 7 ratio is a good day for sure.

That would be a lot of up and downs, who needs a gym membership when you can bring home some AU with a smile and a sore back. 😃

Thanks Aureous for the additional information.

Do you know how wide and high the 11” and under coil windings are? Are they always two high and  however wide?

Thanks for the reply and detailed response Simon, great info!

I hope there’s a revival of these smaller coils with these winding configurations, would be a great idea and a top seller.

I would like to get a 7x12” or a 10x5” like the Exceed and Goldhawk offerings for the  5 pin detectors.

Thanks Simon,

Did you ever get a chance to try one out, curious to know what kind of performance it had working on the 4500/5000 timings. 
Interesting that they discontinued it, seems like it would offer a good balance between a bundle and full spiral.

I was looking through several different coil manufacturers websites and trying to see if any of them offered stacked spiral coils outside of the GPX-6000 coils. There coil descriptions are usually pretty vague and I could not find anything mentioning stacked spiral windings.

From what I have been told the stacked spiral or also called semi-spiral coils for the 6000 our stacked 6 wide and 5 high. This windings type gives the 6000 great depth on small bits.

Has anyone heard of or used this stacked type of coil windings on any non GPX -6000 coils. 

I also am extremely interested in what Minelab could offer to the table after 9 years of working on it.

I am also trying to think of what Minelab could do to add a ZVT upgrade that would not take away from the sales of their other models but would indeed excel at performance even if they only added the CC and Spiral coil options.  I hope there not trying to clean out the warehouses of all the 7000 prior to a new release because that could be another ten years at the rate they now sell. 😓

Oh! Problem solved as I remember Minelab will offer the new ZVT replacement at such a high price that everyone would still prefer buying their older models due to their personal budget constraints. Only fever stricken people like myself would buy the new model and possibly never make a return on the purchase though. 🤐

Another option I am considering is to purchase an older Minelab PI and combine it with the best coil for depth, so that I can use it to go over patches (that I have cleaned out using the 6k) to find larger (3-5g and larger) nuggets at depths deeper than the 6k is capable of.  So just to be clear I want a machine that is dedicated/configured for increased (at least 3+ inches deeper than 6k) depth on larger gold, has a stable threshold and the ability to handle ground mineralization and hot rocks better than the 6k.

Hi Ceril,

Here's a video with some comparisons of the 5000 in Extra Sensitive with 12" & 15" Evo and the 6000 with 11" & 17" coils.

Minelab GPX 5000 12 & 15" Nugget Finder EVO Sen Extra Vs 6000 with 11” and 17”

If you have more difficult ground than this then Fine Gold would be needed and probably have different results from this comparison though.

Keeps getting better 😎

A pulse induction detector or similar technology for handling the ground saturation problems will probably be needed there for the iron issues.

You might consider the gold sizes you might find there and the price range you’re planning to spend on one.
A GPX-4500/4800/5000 are all great detectors for a variety of gold types for a good price.

Everything else goes up in price from there or at least until the Algoforce arrives in the US.

Personally the tests I have done for Extra Sensivity coins have always been deeper than Sharp

Hi Luis,

Yes, Sensitive Extra works exceptionally well on the mid-sized targets. I should have said the Sharp timing has a 20% more power increase to the transmit field over the normal timings. So if were talking about depth on larger deeper targets this would be a powerhouse with a larger mono coil in mild ground conditions, but also this timing is very receptive to ground saturation and cannot be used in lots of situations.

The sharp timing was added to the GPX series to bring back what the SD series offered with the higher regulated coil voltage for increased depths on larger targets though.

I have have also used no threshold around high EMI environments to help better hear through all the noise chatter, just keep in mind that you are still missing the fainter signals with no threshold on kinda a double edged sword though.

DD coils really do not have the ability to get the performance in comparison to the Spiral wound coils. So the older detectors SD/GP’s that needed to run DD’s to handle the more mineralized ground are not going to help out in your situation with moderate to heavy ground mineralization.
 

Smooth timings are the way to go in heavy mineralized environments and the mods also do gain even more depth but these are expensive options to get the depth you’re looking for.

If you’re in less mineralization and can run normal or sensitive timings with a mono 15” Evo coil or equivalent then you could do will getting the depth that you have described wanting with the older models.
This is mainly due to the coil size being bigger than what is currently offered on the 6000 and if you went with the 5000 and ran Sharp it’s even 20% deeper yet but only in low mineralized conditions. 😳

I do a lot of comparisons videos and can send anyone a link if wanting to see different coils compared.

Are Lithium battery packs, either commercial or home made, adaptable to this machine? 

I have had good success using lithium battery systems on all SD/GP/GPX series detectors. I use a step up boost converter on the SD’s to get the 7.3 ish volts to the coil. Only thing with lithium battery systems with an audio amplifier is that you really should have a bypass switch to reduce the distortion when using a Bluetooth transmitter or headphones.

Detacc brand & Jonathan Porter’s B&Z boosters had a bypass switch for a good reason. Detacc don’t sell them anymore though.
