Thanks for the excellent reply.. The operating frequency of this fake is about 10KHz... If I did add more windings of say 30 gauge wire, I could probably get it down to 6-7KHz which would add sensitivity because of longer wave lengths AND reduce the interference it from my Simplex. The Simplex is at 12KHz. My Vanquish 440 does not affect the probe at all. Performance on tiny gold, earrings and chains are spotty any way.. Its the coin detection I want to play with. Naturally a genuine Garrett AT or Pro-pointer are unaffected by the machines being nearby. Since I have this knock-off and it doesn't work that well any way, I figured it'll go to the operating room and see what's what... Thanks again, SF

Oh I HAVE a total idea to what I'm doing, hence the lone question: If I add more enameled copper windings, will it increase the depth field? I don't care what happens to this unit during / after testing or modding, I have my real equipment with a backup of the same.. Thanks for the reply, but not what I implied or asked...

Hello All, I bought a Garrett Pro Pointer off of eBay. It was a fake. I reached out to the seller who promptly refunded the money and told me to keep the probe. What I want to do is try to increase its depth, but not with the oscillator or frequency. The fake comes apart just like the real one, so removing the components is easy. If I add MORE copper windings to the internals, will that increase its detecting field? Thanks in advance, SF

Hello Steve, Been reading your commentary here and there for a few years prior to joining. Just for clarity, The Compass I meant was my mothers Gold Star 1000 that is 6.8Khz, not the 77B. I reread my post and can see how is can be misunderstood. There is no mystique about the 77B, IT CAN and DOES target mask. The 77B was used in hunts for its speed. I honestly never liked the Yukon series with the exception of the Coin Hustler 1, though basic in every way, it works GREAT at the beach in saltwater and has no trouble finding gold. I saw them work consistently for several years. My dad sold a lot of them because one guy on the beach was "knocking them dead"... I got the Simplex and had to tone it down to stop the excessive chatter. Ordered the SP22 Coil and will see how that goes. Frank

From what I gather from info and years of past experience is that: The lower frequency, the BETTER at finding silver coinage and better depth too. Couple that with today's machines capabilities and you get Teknetics Alpha 2000, Teknetics Patriot and the Simplex+. All are single frequency with the advanced features of target id. The fact that you can threshold and ground balance these guys takes you back to the 80's with advanced electronics. I just scored a Simplex for $150 from someone who received as a gift, but just couldn't make it work. It'll be here on Tuesday the 7th. It's 12khz as opposed to 6.8-7.7 of the Compass. I had my mothers Gold Star 1000 out against my sons Vanquish 440. He got 32 coins with 1 silver, 1 wheat and 1 silver ring. I got 19 coins with 1 silver, 8 wheats, and a boy scout buckle... No doubt he can cover more territory, but I believe I got the deeper stuff... The firmware released last year for the Simplex makes it an entirely different machine than what was marketed prior. Have a friend in both Florida and the City that use it and make a killing in "fished out areas".

Hi, I'm new to viewing forum posts, but NOT new as to detecting with 43 years under my belt. I started at 14 with a Bounty Hunter 840. Strange machine, because it went deeper than others of its kind. Turns out that the coil was the reason. How loosely or tightly and how much wire was used can determine some depth differences. A couple of years later, I got the DE-280 Outlaw. It didn't go as deep as my 840. I put the 840's coil on it as they were interchangeable. Boom, it went even deeper. Yes, I had to dig everything, but I was accustomed to the light tone change deep coins would emit. My parents were Compass dealers in NY in the 70s and 80's. My mother had one of the first 5 Coin Magnums produced. It was such a new beast, that even the designers at Compass were unsure of all its capabilities. She MASTERED the machine and often fielded calls from Compass or reported back with updates. In regard to the 77B... This machine was highly desired by enthusiasts that frequented hunts as its speed was unequaled. It can Iron Mask like others rarely could at that time. At get-togethers, owners would show off its speed by throwing a coin as hard as they could past the loop only to hear it blip.. Its 100khz single frequency, but can be tuned to find good stuff in less trashy fields. I'm actually setting up a 77B right now and forgot if it took 3x 9v or 3x AA-4 packs.. That's how I stumbled on this thread. It takes 12 AA's... If you want a 77B for primary shooting, I would say NO, unless it was used in low trashy conditions or if you were nugget hunting. I would HIGHLY recommend the Minelab Vanquish 440. Its a coin vacuum and the target ID is top-rate at a reasonable cost. Happy Hunting...
