Fisher F22 Review: Weatherproof Is Not Waterproof, and That Is the Whole Review

Coverage across the situations a genuinely new detectorist meets in a first year: parks, yards, fields and light rain, all handled by one machine with no configuration beyond a short menu. Fisher publishes discrimination, sensitivity, notch filtering and pinpoint mode, plus target categories layered onto the 0 to 99 scale so a beginner gets both a number and a rough category read at the same time.

The weight matters more than it looks on a spec sheet. At roughly 2 lb with a padded hand grip and arm cup, this is one of the lighter machines in its price bracket, which shows up on hour three of a session rather than hour one. That combination of light weight and a simple, turn on and go control layout is why this model appears repeatedly in best machines for seniors style roundups across the hobby.

Published figures only. Fisher publishes fewer numeric specifications for the F22 than Minelab publishes for the machines it competes with.

The wording each maker chooses here is not interchangeable, and this table lines the three claims up side by side.

Fisher's own copy for this machine says it can find treasure "on land and shallow water" and that it is weatherproof "for use in the harshest weather and environments." Read those two claims together and the message is consistent: rain, dew, damp sand and brief contact with shallow water are fine. What the listing never states, at any point, is a depth rating for submersion. Compare that with Minelab's explicit 16 foot figure for the Minelab X-Terra Pro or Nokta's explicit 16 foot figure for the Nokta Simplex Ultra, both published in plain numbers. Fisher chooses not to publish an equivalent number for the F22, and a listing's silence on a spec is itself the spec: treat this machine as unrated for submersion and never intentionally put it under water.

Second, single frequency with no multi-frequency claim anywhere in Fisher's listing. That is a fine trade for parks and fields, where the ordinary iron-versus-coin problem is separation rather than salt. It becomes a real limitation the moment salt water or heavily mineralised beach sand is involved, for the reasons the frequency chart sets out. This is a land and light-water machine, not a beach specialist.

Third, Fisher publishes little beyond the headline bullets for this model: no stated coil compatibility list, no published battery runtime figure and no stated waterproof depth in feet. That is common at this price point and it means a buyer relying purely on the spec sheet is relying on a short document. The F22 target ID chart fills part of that gap with ranges rather than a claimed lookup table.

Ease of use and weight dominate published owner reviews of this machine. New detectorists consistently describe getting to a usable hunt within one session, the 4-tone audio as easy to learn, and the light build as comfortable for long park sessions and for users who cannot manage a heavier machine. Several published reviews specifically mention buying it as a first machine for an older relative for exactly that reason.

The recurring complaints track the weatherproof, not waterproof, distinction directly: owners who assumed beach-ready meant submersible report being caught out in the surf, and some report reduced stability on wet salt sand, which is consistent with a single-frequency machine working against conductive ground. Owners also consistently note that their target ID numbers shift with soil moisture, which is why bury-and-check testing against your own machine matters more than any published chart, including this site's own.

Buy it if:

• You want a light, all-round first machine for parks, yards and dry fields.
• You want a genuine 0 to 99 target ID with 4-tone audio at a low price.
• You expect occasional rain and damp ground, not wading or diving.
• Weight matters more to you than a deep feature list.

Skip it if:

• Any part of your plan involves submersion. This machine states weatherproof, never waterproof.
• Salt beaches are your main ground, where a single-frequency machine struggles regardless of coil.
• You want a stated waterproof-in-feet figure in writing, in which case the X-Terra Pro states one.
• You want a larger LCD and more readable display, where the Fisher F44 is built for that specifically.
