The NYC Toy fair 2008 there was only one metal detector maker and that was Bounty Metal detectors - they have an entire line from simple ones (inexpensive) up to beefier ones that ... They are compact and lightweight and usually require no initial calibration. Not to bad with the very low Humidity. However one should take note that the optimum depth for detection is not more than one meter. use the local library or the internet to find sites that were used in the past. Multifrequency detectors are considerably more expensive but offer the best of both worlds and are quieter and more resistant to interference. We added something new to our metal detecting accessories a couple of weeks ago. doesn't hurt to dream.
