The DetectorPro Pirate Metal Detector is a water pulse induction
metal detector. It is specialized. It is usually used in salt water.
It has no discrimination at all.
The Laser Hawkeye is an OK machine. I am not sure if it is worth
the extra money for the display though. It is a good jewelry finding
machine and a good relic machine. I like the Vaquero better. It has
no display, but it does have ground balance. I am wearing mine out.
The Tesoro Tejon is the only one you listed that has ground balance.
That may, or may not end up being very important. If you have any
issues with reactive ground conditions, it will be important. The Tejon
is a real good relic machine. It would even do pretty good looking for
gold nuggets. It's sensitive and deep. It may be a bit of a beast for
a newbee.
The Garrett Ace 350 Metal Detector is the coin hunter machine out
of those listed. It is like the 250, but it has a Double D coil and it has
some iron handleing settings that the 250 doesn't have. I would rather
have the 250 and two coils for about the same price, maybe. It is not
hard to tell iron with the 250 when you learn it.
I would like to buy a Tejon.
Happy Huntin,
