Fisher F44

The Fisher F44 sits at the top of the weatherproof F-series and gives experienced hobbyists more control than the F22. It keeps the 7.69 kHz frequency but adds a true All Metal mode, computerised Ground Grab with manual ground balance, and a larger 11-inch triangulated concentric elliptical coil for extra ground coverage. It is the best choice in the F-series for users who want to tune the machine themselves.

Five modes – Jewelry, Coin, Artifact, Custom and All Metal – let you switch between discriminating trash and hearing every metal target. A backlit display with 1–99 target ID and nine segments, four-tone audio and Fe-Tone iron volume help you read signals, while fast recovery speed helps separate targets lying close together. Settings such as sensitivity and volume can each be adjusted across twenty separate levels.

The IP54 weatherproof control box, waterproof coil and 2.3 lb weight make it practical for long days outside, running on two AA batteries. Kellyco lists it as made in the USA with a five-year limited warranty. In Pakistan the F44 suits hobbyists hunting fields, beaches and old sites who want ground-balance control for mineralised soils. Its larger coil gives better ground coverage when searching big open fields or long beaches.
