The Fisher Impulse Gold is a new ground balancing pulse induction (GBPI) metal detector with probable availability in 2021. The new Fisher Impulse Gold is a gold prospecting model being developed alongside the Fisher Impulse AQ model, which is intended for beach and water hunting. The Impulse Gold is expected to offer excellent depth and superb sensitivity to small gold nuggets due to an very low pulse delay capability. The compact design and light weight is also attracting a lot of attention.

A major design difference from the AQ model will be the inclusion of a ground balance control to deal with mineralized ground conditions. There may or may not be any ferrous discrimination features as are offered in the Fisher Impulse AQ due to the almost infinite range of target id numbers spanned by naturally occurring gold nuggets. It is likely that this model will also find applications with relic hunters, as has been the case with previous pulse induction gold prospecting metal detectors.

Production of the AQ Limited ceased in December 2020. According to this post, the final Impulse AQ will be released by July 2021, and it will sell for between $2800 and $3500. How this relates to the Impulse Gold model is unknown at this time.

The photo below shows the Fisher Impulse AQ prototype - the Fisher Impulse AU is probably of similar design although testing has been mentioned with a smaller coil.

New information will be added here when available. All information here is very preliminary and subject to change, especially pricing and final specifications. Everything is really just guesses based on the Fisher Impulse AQ plus a couple things mentioned on the forums, such as the coil size.
