Sov GT Super Slow Recovery

[Critterhunter]

The only thing that concerns me about shortening the coil length being of no advantage is what I learned in my electronics courses. The laws of physics are that the longer the wire the more resistance and thus the less voltage available at the load (coil). What concerns me is when you are talking about this machine using so little power (is it 50 millamps?) any small amount of resistance might be something that could alter performance.

I say "could" because that's all speculation on my part as I'm sure coil makers know more about this than I do but it's an added potential benefit if anything. I also wonder if they are taking into consideration the other factor....the longer the wire the more electrical noise, resulting in a lower sensitivity setting and less depth. I wonder if they are they testing that in the lab too? I plan to shorten my cables for looks and to save a little weight. I can at least believe it's also going to help the depth by picking up less electrical noise and also making more voltage available at the coil, along with the four leaf clover I carry in my pocket...

Thinking about your shielding you may want to use aluminum foil tape on cardboard, this way it would be safer and stay in place. It comes up to 3mm or thicker I think. Just an idea.

Did you come up with this yourself or what?

In my soil, red iron bearing clay. I can hardly ever keep a threshold unless I set to auto sensitivity. If I turn it W-A-Y down I can keep a bit but I don't like running at 4:00. I usually run between 11:00 and 1:00 and get a threshold occasionally. I still seem to hear a signal if I pass over it. Sometimes I just set the threshold where I can barely hear it and flip over to silent search.

I am going to try your idea tomorrow. I am just interested in knowing more about it. Why it works, how you came about it, anything you know... i'd love to hear it.

Thanks,

Julien

Get some shielding material from a luthier supply company like Stew-mac: http://www.stewmac.com/shop/Electronics,_pickups/Supplies:_Shielding/Conductive_Copper_Tape.html?actn=100101&xst=3&xsr=158

or Warmoth: http://www.warmoth.com/Copper-Shielding-C214.aspx

or you may can pick up some at Guitar Center (but i'd call 1st): http://www.guitarcenter.com/DiMarzio-Copper-Shielding-Tape-364741-i1130577.gc

I can't imagine how a little epoxy on the bottom of a coil could possibly have any effect on a warranty. I mena. I cna see where someone might try to make it an issue but if done properly I cannot see where they wouldn't look foolish trying to void a warranty over it. Yeah, if you get it all on the connector or something but on the bottom of the coil... shouldn't be an issue and if it did cause a problem, then there was a problem with the coil anyway if somehow the epoxy got in it and messed it up.

I wouldn't worry about it. No company wants the sort of bad PR that would come from voiding a warranty over a user taking care of the product.

I think I read in the beach forum that some guy had sanded down the bottom of his 10x12 or 12x15 coil to drop a bunch of weight. If I remember right I think it dropped it to 16 ounces but need to dig that post up. I think some coil companies, rather than putting two halfs together, flip it upside down and fill the entire thing with epoxy so there's no bottom cover on it. If that's true then there is your reason why some of these things are so darn heavy. Coils need to be glued in place but you don't need to fill the whole thing with epoxy if you do it right. I think that's why some coils are called waterproof (entirely filled with epoxy to prevent leakage) where as others are somewhat hollow and any pin hole in the plastic case could fill it with water. Anybody have any thoughts on this?
