Thanks for all the responses. Out of curiosity, how does the Teknetics Eurotek Pro compare to something like the , gold bug pro, Tesoro Compadre, or the AT Pro? I've read good things about it the Teknetics and it seems like about what I what. What am I getting by spending more for the AT Pro, or what am I losing by spending less for the gold bug pro or Tesoro Compadre? Is the Teknetics even any good?
There is nothing wrong with Teknetics line and I don't even own one, but if that style detector suited me, I wouldn't hesitate to buy a teknetics. If you can spend up a little bit and are interested in Teknetics, take a look at the Omega. Bart at Big Boys Hobbies or any of the other forum sponsors can give you good pricing and advice with a phone call.
At the lower price end of the spectrum, if that is what your budget allows, consider the Compadre, Silver uMax, Alpha, Delta, F2, F4, Xterra 305, Coinmaster, or Ace series. Any of these lower priced detectors will find you enough to pay for themselves rather quickly if you put a fair amount of time into them and hunt good locations.
Remember that in your budget you need to leave room for headphones and a Pin Pointer. Decent headphones are a must not only because you can hear targets much clearer, but also others can't hear your detector and will be less likely to bother you.
You will get many brand opinions here from loyal users. Read all the reviews you can on the one that interest you. When reading the reviews not all the bad ones are bad. By that I mean if you read some that are bad you can tell the user was clueless and expected to get rich instantly.
All that said- now my recommendation. I would seriously consider a Compadre, good headphones, and a Garrett Pro Pointer. If you can swing a little more I would go for the Silver uMax or Cibola. As you have just guessed I am a bit Tesoro biased, but hey, the work really well for me and have a lifetime warranty.
In the end stick with any of the major brands: Whites, Minelab, Fisher, Teknetics, or Tesoro. Take your pick, do your research, and most important spend the time to know your detector really well. Give it some time to learn it and know what it is telling you.
