How it differs from its neighbors
Teknetics' T2, from the same maker, runs at 13 kHz too, with a 1 to 99 target ID on a large LCD. Its T2 page gives no weight, coil size or battery; the F75 page lists all three.
Fisher's Gold Bug Pro sits at 19 kHz with a smaller 5-inch DD, at 2.5 lb. The F22 sits lower, at 7.69 kHz, with a weatherproof control housing and 2 x AA for power.
Fisher also sells the F75 LTD, which adds Boost and Cache modes and a 5-inch coil. All four models here carry the same warranty of 2 years.

Questions about the F75
Answered from First Texas Products' product page, read Oct. 16, 2026.
The coil is. First Texas gives two answers for the control box: not weatherproof and not IP rated on the spec sheet, weather-resistant construction on the product page.
The maker says the F75 LTD adds Boost and Cache modes and a 5-inch coil.
Up to 40 hours on 4 x AA (not included), by First Texas's rating. That is longer than the 25-30 h it lists for the F22.
