You know Badger, seeing your comments on the Silver uMax, I'm mighty tempted to go get one, with the large coil, and give it a whirl. Nothin to lose. A little off the topic, but have you ever tried the Vaquero?
Jim.
The Silver uMax machines do differ in depth so I'd get a new one or buy used from some honest person. And make sure it's the newer Silver uMax. The older Silver Sabres, Conquistadors, Banditos, etc., aren't nearly as good. I used all of them and the Silver uMax is the one to get.
Here's another thing I've learned. My Tejon got very unstable if I didn't keep it ground balanced. I often had to turn the sensitivity way down and GB just to keep it running right. The same was true of the Nautilus IIB. The Silver usually runs smooth as silk at full sensitivity and I only need turn it down occasionally to maybe 9.
The biggie is the Silver with 12x10 is finding lots of deeper/smaller copper and silver items the Tejon, Nautilus, and even my GT totally missed.
One thing I didn't write in my story on finding the ancient coins was I had hunted those exact spots many times with all my other machines. I never got a beep. The Silver with the 12x10 gave a very solid signal on all.
Jim there's no question that in our soil here the Silver is the better coin machine. But in extremely trashy sites I'll still use the GT (for now anyway).
But too I've found the 12x10 separates targets extremely well. I dug a 22 shot yesterday at a good 8 inches. It will do BB's at 4-5 inches. It's a myth that bigger coils can't detect small targets.
Jim you've been around the block and you know coil size and depth are directly related. Only so much power out requires a bigger antenna for greater depth (Nexus). I read these fables of greater depth using a smaller coil. Smaller coils can mean less masking but I've discovered that's not the big problem. Most old coins and trash run about 4+ inches deep at old sites and at that depth almost all coils are smaller coils.
And too, the 12x10 coil will give a good/bad signal with extreme masking. I simply check the targets from differ directions and raise the coil a little and bingo! The Tesoro coil separates without losing depth with a dinky coil.
When I pull coins from 8 inches with my 12x10 concentric my actual coil size down there is maybe 4x3 inches? At 8 inches a 5 inch coil won't even see the target.
Jim, there are finds out there deeper than we used to think they were in the old days. I found this out when some grounds were damaged my a careless heavy equipment operator. I checked a deep ditch and found a very nice old heart pendant 7+ inches lower than the trench! I later found lots more goodies this way.
The THing in the future will be digging all the deep stuff this generation missed because we thought it wasn't there. Some new type of machines in the future will open up a whole new movement in coinshooting.
I'm trying to get Tesoro to make a round 15 inch concentric uMax web coil but I doubt they'll do it. The reason being they can't put a bigger concentric coil of their "hot" machines because they get very unstable (yes, they've tried it). The uMax is a better system than the "hot" series and the big coils work with them. But this would make the low cost Silver so obviously deeper than the expensive models that this could prove bad news for sales. Tesoro needs to sell some expensive machines or raise the price of the Silver. But, with competition the way it is, raising the price of the Silver would be very risky for them.
WOW! What a machine a Silver uMax would be with a 15 to 20 inch concentric coil!
Try thinking rings/cobs at the beach at 20 inches!
They've been trying to sell us all this banana oil about PI being the perfect future system. Georgie of Nexus showed us what is needed is a better coil for the VLF.
You can get the 12x10 concentric (for uMax) used. Many people bought these a few years ago and never used them. I've bought 3 so far (2 went to others). I got one from a dealer someone had returned. It was mint for $80 delivered. $80 shipped is the going rate for a used 12x10 in excellent condition. If it's beat-up about $50.
My present Silver cost me $170 shipped. It was mint used condition.
So for a total of $250 I have a deeper machine than a Nautilus IIB (maybe deeper than the GT). And, it's lighter and a million times more fun to use!
If I ever come on a $1 gold piece this machine will easily see it.
No, I never tried the Vaquero. I always went with the Tejon.
Best,
Badger
..I'm not here to argue and want, I'M to Busy..I just know I like my F75..Because it works for me thats all....If I had a whites,Tesoro,Minlab...It would be cool, I am no way shape or form Brand Loyal If Its Junk its Junk..My unit Aint It acually works great from salt Beaches to Hi-Mineral grounds..As a matter of fact I am thinking hard of getting a good used Tesoro silver-Umaxx for quicky park hunts there lifetime warranty is awesome.. I went and looked at the Whites DFX and MXT today... WOW There Built with quality they look Great I see the Differance..They may be a tick heavier But I agree there Built like a tank...and look Great!!!!
The F75 wasn't it. Yes the build quality of the F75 is very poor.
