I just bought a Euro Sabre. This is not my first Tesoro I've owned the Vaq, Cibola, Orig. Bandito, Royal S, still own the mighty Compadre now the Euro Sabre. SO I have a good understanding of how these machines work. I detect alot of iron infested sites and own several other machines that work very well. My favorite is the old Compass GSP it will pick through iron with a quickness. When I read about the Euro I thought it might be kinda cool that I could hunt with no disc. and use the three tones as the disc. to try and find a few goodies that were mask by nails. I tested the machine in my badly mineralized depth killing, coin garden and was amazed that it was giving a weak but repeatable high tone on an 8" dime. I thought whoa this is monumental considering the F75 and Etrac don't seem to hit this dime any better. So I'm stoked up to say the least, then yesterday I took the Euro to a nasty iron infested site and tried my idea with the no disc. hunt by tones and found that the machine was audio masking terribly. While I am sure the machine was seeing the conductive targets, I couldn't distinguish them from the constant rolling high/low sounds, no clean or even semi clean conductive high tones. Mind you I was using the 8x9 web coil ( I had not got my 5.75" coil in the mail yet). Now I know this would of had a big masking effect on how the Euro seen the conductive targets in and amongst the iron but I never dug 1 conductive target yesterday. I did however dig a lot of questionable big deep iron that gave some what of a rolling tone but sounded strongest on the high tone. I did find a few 22 cal. hulls on top the ground that also gave rolling tones while laying on the ground but would signal as high tones swung near the coil in the air. HMMM.
I swapped over the the Blank Tone ID and trying to find high tones then verify with the Audio ID but they would all be rolling in this mode. Then I tried to turn the audio ID of and just hunt with the Disc up to just below foil but then got a multitude of solid hits that were bigger approx. 3" nails and small bits of flat iron. These would not disc out or start breaking up until the disc was turned to pull tab range, hello masking I thought. ,
I got the 5.75" on the machine today and again went to the coin garden and the best I could do was 3" on a merc. This was GB dead on sensitivity in overdrive and everything in between, even tried the Supertuning with the threshold that I used on the Vaq. and Cib. nothing I did would cause the machine to detect any coin over 3" in my test garden. This didn't make sense as with the 8x9 web this was by far the deepest Tesoro I've owned to date. Any Ideas - tips - would be appreciated.
