Hi Guys Ok well this is just MY personal finding Ok.
I was honoured with the presents of PRO Graham Ashton with our testing of the new NF coils. Firstly I heard that Gold search Dunnoly had the first run of the 12 inch mono Evolutions coils so not to miss out as times is short I simply brought one with out testing with the pretence of picking the 12 inch Evolution up and borrowing the 15 x 13 NF test coil which we did last Tuesday. We went an area of mild to high mineralization near Dunnoly and buried a 0.6 grm low porous specimen Nuggets. (one that the GPZ 7000 has difficulty in detecting.
Buried it a 150 cm 6 inches in packed down ground.
Ok all the test where with two separate GPX5000's setting then same at RX 12 Stab 10 audio quiet Special fine gold. Tuning 100 Target volume 12 signal 16.
NF 10 x 5. 6 - 7 inches a clear sharp signal.
NF 12 Inch original minelab 6 1/2 inches clear signal
CX Coiltech Elite 14 inch 8 - 8 1/2 inch clear sharp signal.
New NF 12 Evolution very quiet a clear sharp signal 8 - 8 1/2 inches.
New NF 15 X 13 Evolution at 8 inch the evolution only detected a signal mid coil not from the edge (not like the other coils strange) and it wasn't a sharp clear signal as any of the other coils particular compared to the Coiltech Elite 14 inches or the Newt NF 12 Inch evolution
Personal Summary .
Im very glad I'm purchase the 12 Inch NF evolution it quite and is really impressive; no noise when you bump objects picks ups really small targeted and has the depth on larger ones the is an excellent coils . I'm glad to have added it to my coil arsenal.
Im happy i didn't purchase the NF 15 X 13 Evolution.
The 15 X 13 evolution for me personally and with the supervision and agreement of Graham Ashton woo for the money of $490 this coils is a disappointment. That my opinion. OK
As many of us who have resisted the push to buy the GPZ 7000 we are looking for future improvements in coils technology, at present the big boys coils produces are all bring out their new coils but its really important (if money is an issue) that we test them out for ourselves and find those coil which we personally prefer and perform as we expect.
I presently have the Detech 8 inch mono a great coil for those mulik-heaps a NF 14 x 9 elipical as a really great all rounder the a 12 Inch Minelab but I find its depth slightly less than I would like and its noisy when you bump it again objects a NF 14 inch round mono which is really quite and easy to swing but it doesn't pick up lead shot pellets (maybe a good point) I may replace this with the Coiltech 14 inch Elite but before I do that I'm going to test out the Very new ultimate Detech DD 15 inch from review so far its a very impressive coils but it is heavy at 1.3 Kg. Initial impressions is its very good on small target in Fine gold setting and can be run in Normal on large target at ridiculous depth's (interesting to see how it handles mineralization on normal) and it also runs well in Mono which would be a really benefit particularly for us over here in highly mineralised soil in Victoria.
Another really important point is "Coil Manufacture's Quality Control" this is a major issue to me as it should be for everyone. In my professional life I am involved in the airline industry so I'm very familiar with quality control and value for money as I'm an Airline Captain.
I have personally had two NF coils replaced due to poor performance compared with other people similar coils a NF 14 X 9 elliptical and 14 Inch Mono returned and replaced due to poor quality.
Therefore if you do get the opportunity to test a new coil and you decide to purchase one; after you purchase it do re-test your new coils performance agains the test coils; after all it your money!
Good Hunting.
