How it differs from its neighbors

First Texas sells the F22 in two versions. Its stock version has a triangulated elliptical waterproof coil of 9 in; the F22-11DD has an 11-inch coil. The listing we link is the second.

The F44 keeps the 7.69 kHz and a weatherproof housing, with 5 modes including Custom and a 9-segment target ID with 4-tone audio. Fisher lists it at 2.3 lb, and an F44-11DD version exists too.

The F75 moves to 13 kHz on an 11-inch BiAxial (DD) elliptical coil, and weighs 3.5 lb. All three carry a warranty of 2 years.
