Didn't woof used to post here. I've seen Alper posts from Nokta. If Sven is not an electrical engineer he is close enough. If there are not engineers or designers here, I would wonder why.
I live in Colorado but do not see what difference that makes.
I don't know why you say I don't want actual field recoveries. I would welcome them if the person making the discovery use both types of detector. If they used both before recovering, that would be the most significant to me.
I have seen and read about "actual field recoveries" by experienced detectorists. Some use smf, some sf, some ssf. Some of the time, they say "this new one allowed me to find all kinds of things I couldn't find before". Is this the reason why; the technology is better? I love to see "actual field recoveries made by experienced detectorists", but I know that they use all the different technologies and they all seem to work. I don't know why some use smf technologies., I don't own one. I know why we do not use BFO detectors in spite of being able to detect coins underneath nails. I don't know why people use simultaneous frequency machines because I do not own one. If there is a logical reason why I should have one I want to know. How does watching Gary from XP detectors make finds help me know why the one he is using better than say a Minelab? How does reading about finds from a person who uses a Minelab help me know why Minelab is better. If it finds silver better, and some think it does, is it because of the slower recovery time, the more understandable signals, the smf, or some other reason? Simply put, does watching or reading really tell me why one is better than the other? I want to know the advantages of both from people who actually use both and I know they exist. I have seen some who have switched and belittled their old ones. This is not what I am searching for. It seem more meaningful if the detectorists still use both technologies.
Picket, soil is different no matter where you go, so you need to adjust to your environmen but that’s besides your point.
Maybe you should contact those scientific/engineers directly, better yet called and let us know what they tell you.
I owned a CZ 7 and loved it for a few years. That dam thing made me dig more dimes because of the tightness of the screen vdi.
I dug dimes I didn’t think we’re good but out came barbers that were worn very thin. My problem with the CZ7 was ground balance; I always struggled with it and never knew if it was good or off. But still a good coin shooting machine.
When minelab came out with FBS machine I didn’t bite right away, I waited for folks to review in New Jersey dirt or sand.
After awhile results came in and man those guys were kicking my pants With recoveries, (this is my experience from observing finds displayed at metal detecting meetings).
You should do the same - go to some meetings and see what is being found and with which machines, that way you have a good idea of what works in your area and with your own detecting knowledge.
I have been detecting since 1991, no expert but have many hours of field and or asking the same question as you…..why? Which is the best?
After using my ExpII for over ten years I bought the NOX. I loved the knew technology and for me it was an easy crossover (being a minelab hunter for some time).
You going from a CZ to a Minelab will have a learning curve. But there are books and how to online. Not the stuff where a guy finds a merc, the ones that explain how too Or how it works.
Now for me a Multi frequency is exciting because they made a change to the existing software of the FBS. Full Ban Spectrums sent out many frequencies at the same time, like my EXPII did. Now the NOX sends out similar frequencies but in a different pattern, so to speak.
Is it better than a CZ, well that depends on the user not the machine. I enjoy minelab and try real hard to understand what it’s telling me but that’s me thinking out of the box.
Now, you need a test garden and a friend who has a NOX, then you both test your machines over those targets and compare. There is one guy who lives in the south and compares his test garden to many machines and puts that stuff on YouTube his name online is calabash digger. His soil is mild so understand yours is probably more mineralized, I would think but could be wrong. They used to mine in Colorado like lead, gold and stuff.
This might help and might not, I hope others can chime in to assist you in the same questions we all have.
Best of luck, get out and enjoy this crazy hobby!
