One step down the Prizm lineup from the Prizm IV comes the Prizm III. Here's the White's page on the Prizm III where they say "Coins, rings, nails, pulltabs! Hear and see your target as you hunt. Push a button and pinpoint the exact location, then readout target depth!" White's also has great product pages so be sure to stop by to also see info on the Prizm III's warranty, recommended accessories, and some pictures of the Prizm III.

Well as of this writing there is very little information on the web about the Whites Prizm III, maybe that will eventually change. Is the metal detector that unmentionable, or is it the King of treasure hunting and everybody's keeping the secret to themselves? Well there are at least three opinions right now over at Metal Detector Reviews. But even there the reviews are lackluster not offering much in the way of advice or tips on the Prizm III.
