How it differs from its neighbors

The F22 runs the same 7.69 kHz. It has four modes, Jewelry, Coin, Artifact and Custom, and a 9-inch triangulated elliptical coil. Fisher calls its coil waterproof, with no depth rating. Its weight is given only as just over 2 lb.

The F75 moves up to 13 kHz on an 11-inch BiAxial (DD) elliptical coil. It weighs 3.5 lb and lists 40 h on 4 x AA (not included).

Teknetics' Omega 8500, also made by First Texas Products, runs the same 7.69 kHz and weighs 2.5 lb. Its battery is listed as 1 x 9 V (not included). The F44 warranty runs 2 years.

Questions about the F44

Answered from First Texas Products' product page, read Oct. 16, 2026.

Not by any published rating. First Texas calls it weatherproof but states no rating for the coil or the control box. Keep it out of the water. The Amazon listing calls its DD coil submersible; the maker publishes no rating for that coil.

A second F44 version, also sold as the F44-11DD, with an 11-inch DD coil instead of the 11-inch concentric. That is the version on the listing we link.

The maker lists up to 30 h on 2 x AA batteries.
