I am not sure if anyone else is doing this (it appears to be a Coiltek sale but no mention on their website), but Chris at AZO is advertising Coiltek coils for the Minelab SDC 2300 at 20% off for the rest of the month or while supplies last.
20% OFF the following premium Coiltek products:
• 10x5 Gold Extreme: WAS $295 - NOW $236
• 11" Gold Extreme: WAS $315 - NOW $252
• 14x9" Gold Extreme: WAS $315 - NOW $252

Been reading a lot about the new Coiltek, Nugget Finder & now Detech coils of late. I haven't had much to do with any of these but have detected a small area immediately after 2 x GPX4500 with the Coiltek Elite 14" mono attached. Although not an exhaustive or scientific test the end result was I got 8 x subgram nuggets from the area with the SDC & the 4500's nothing. 2 of the subgrammers came from adjacent to their scrapings so they knew something was there but was still iffy enough to walk away from. I keep hearing or reading how these coils are transforming GPX's into SDC's or even GPZ's but this short "test", for want of a better word, put some doubts in my mind.
I've got no doubt that there is improvement in the new coils in how they enhance the target information or audio response of the detector through better windings etc. but I'm not entirely convinced it's as substantial as some make out. My thoughts are it may be about 10% performance improvement (every bit does help regardless) & 90% of a placebo effect i.e. you buy a new coil excited by the possibilities of it's performance, you regain some enthusiasm & become more positive in approach even detecting more carefully + with more purpose - then when you find gold of course it's the new coil that done it right?
Another thing that has me scratching my head is how excited people are about them finding very small gold. My smallest bit with a GPX5000, fine gold & standard 11" Minelab Commander mono coil was 0.03 of gram (I think about 0.46 of a grain) so they have always been capable of doing it even with an unfashionable coil (but still a good one).
Like I said I'm not doubting that there are definite performance improvements, much like the introduction of litz wire, but I do believe a lot can also be attributed to a refreshed or reinvigorated enthusiasm too.
New detectors could also have a very similar affect on us. What do the experts reckon?
Just curious how it does on depth and sensitivity. Has anyone tested the Elite with some specimen type gold that the GPX misses but the 7000 screams on? Is anyone even running one over here? Most of the comments I see are in Australia. NF looks to also be coming out with a similar coil. I'm just curious how much and what sorts of improvements they give.
So this Saturday im heading back out to the property that produced 4 nuggets with the GPX 4800 last time, using the 11 inch coiltec elite.
The area we will be focusing on has mainly been known for producing larger nuggets in excess of 5 grams. My question is, is there any advantage to use the 11 inch coil vs the 15x12.
The 15x12 obviously gets more ground coverage but would think the two would be about equal on depth to larger nuggets. The 15x12 is probably less responsive to smaller nuggets compared to the 11 inch.
Which would you use on ground that was just clear cut with targets that will generally be on the order of 5 grams or larger?
Thanks for the help
I was wondering if the aftermarket coils were that much better than the Minelab, i.e Coiltek.
I'm very hesitant to go Coiltek because the GPX was designed to use only Minelab coils?
My fear is i don't want to hurt my GPX 5000 in the long term by putting a coil on it that Minelab doesn't like?
It seems like everyone with a GPX is using a aftermarket coil. I especially like the Coiltek 9" Elite
I'f you were me would you get a Coiltek coil?
