New Fisher Impulse AQ Ltd pulse induction metal detector

The Fisher Impulse AQ offers excellent depth and superb sensitivity to gold jewelry - the machine is highly optimized for finding gold rings in particular. The most anticipated feature is discrimination better than that currently offered on any other pulse induction metal detector. The discrimination is focused more on high value gold rings than coins, and may actually exclude many coins if enabled. This is not considered a problem for many serious beach hunters as a lot of time is wasted recovering coins under difficult conditions when gold rings are actually the desired target. The compact waterproof design and relatively light weight is also attracting attention. Other Impulse models are expected to be aimed at gold prospectors and possibly even the relic/coin detecting market.
