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

Wicked Bang For The Buck!
I received my Ace 150 as a birthday gift this summer. I must admit it does take a little to get used to, but once you have figured out all the features and signal sounds you will be on your way to digging up a bottomless pit of goodies! As for the pin pointing complaint I have no problem with it. I do the "X" pattern over the signal and can come within 1-3 inches of the target. I find that some of the newer Canadian coins do not fall into the coin range but actually into the iron segment. But who really cares! I am sure most detectorists aren't interested in digging up 2007 quarters anyway!

As for the good stuff like silver, copper, and brass items they sound nice strong signals in the coin range that you can be about 90% sure with some practice you will be digging a worthy target.

Pennies and silver coins sound a repeating bell tone when you position the coil directly over the top of the target. I hear a lot of novices complain that it can't find gold alone but it falls into the pulltab range. This is true but one thing to remember is that even a $1000+ detector will give you the same signal! Just keep digging up those pull tabs and you will find gold! This detector is one heck of a deal for the price so don't be deterred by some of the negative comments you may have heard. Just be patient and learn what the machine is telling you.

Remember that the detector is just a tool to find the metal, and you are the real detector! I hope this review is of help to anyone interested! Thanks for reading!
