New Search Coil Tryout

[sounder]

My buddy just ordered a new Super Magnum 10" search coil for his BH, and says that I can try it out on my BH Quick Draw II . I will let everyone know what it does for my machine. Hopefully it will get me a little deeper. sounder

Good luck. You should get more penetration with a 10". I use a 10" on my machine and have dug ferrous metal targets in all metal mode down to 24" easy while still getting a nice strong tone.

Well, my buddy got the new 10" coil for his 202. The first thing we did was to put it on my Quick Draw II. We ran an air test for depth, and found that it didn't do as good on my machine as the stock 8" coil. We put it on his 202, and in the air test it didn"t seem to get him any deeper, however, later in the park he was digging coins up to 8 inches, which he has never done before with the 8 inch coil on his machine, so it did help him, but I don't think that I will buy one. He did say that he thought that he could pinpoint the coins easier with the bigger coil. sounder

Glad to hear it. Anything that can put more finds in the pouch makes it worth it

hello sounder, could you tell me what an air test is?thanks. mark

mark, I hope that I called it the right thing when I called it an air test. What we do is to put a coin, usually a quarter, on the ground(where there isn't already a signal) and run the detector over it. We stand a wooden yard stick out at the edge of the coil, and watch how high up the coil gets before the signal is lost. This should tell you about how deep your detector is going. Personally, I think that the detector will go just a little bit deeper when the coin is buried in the ground, because of the minerals "leaching" the metal in the coin, and creating kind of a halo effect. Thats just my thoughts, and it probably isn't right. Anyway, that is the way that I do an air test. Most of the books that come with your detector will tell you to lay your detector on a table or flat surface, and hold a coin out in front of it, and see how it sounds, and how far away it will detect. What I do is about the same thing, but I find that if I try it in the house, I sometimes get interference from electrical sources inside the house, so I take it outside. I hope this answers your question. sounder
