Teknetics Alpha review
Took the Alpha to an old ball field for a few hours. The site was on a slope were the old bleachers had been tore down. Iron was everywhere. Important to note, that is why I chose to run the discrimination wide open. If the detector can id iron then there is less chance of masking or iron sounding like a good target.

The detector ran very smooth at full sensitivity with no chatter. I tested the EMI issue under power lines and the field light transformers and no problems at all. Honestly I was very surprised. Early on the Alpha had problems with EMI. But Teknetics fixed this with heavier coil cable. The "56" nickle I doug was actualy showing 5c on the display. 4-5 inches down in the red clay here. I was spot on with the pinpointing also. As I am use to Tesoro's I just X'ed the spot. Although nothing earth shattering was found by me I feel this detector is worth more than it's price. No ron, none no nails or can slaw. And trust me it was everywhere. It likes pulltabs. That is a good thing to me because it will like gold too.

The dime I found was proof that leaving the disc. open helps find good things in iron. I got the low tone before and after the small high tone. I thought I better slow down my swing and listen. Sure enough I could here a hight tone between the two low tones. So I dug and out popped a clad dime. Now I'm impressed. Depth is not an issue either. The last target I dug was a memorial at 7" next to the side walk. Are their any bad things with this detector? Not realy, for 200.00 it can't be beat IMHO. The stock 8" coil is ok but I am getting a 5x10 DD to realy enhance this detector. HH
