Fisher F75 Review
Fisher F75 remains a fast, information-rich 13 kHz relic detector with FastGrab/manual ground balance, all-metal modes, mineralization display and a light balanced chassis. It is technically capable but now competes with waterproof SMF machines.
Bottom line
Still excellent inland; difficult to justify near modern SMF pricing
Buy F75 for dry-land relic sites where its audio speed, ground information, process selection and 11-inch DD coil matter. Skip it for submersion, regular wet salt or users who want simple presets. Its control box is not waterproof, and its deep menu of processes rewards experience rather than casual use.
Decision table
Fisher F75 specifications that matter
| Decision factor | Documented position | Practical consequence |
|---|---|---|
| Frequency | 13 kHz single-frequency VLF | Determines how the machine approaches targets and changing ground. |
| Water protection | waterproof coil; control box not submersible | Separate housing protection from wet-salt stability. |
| Best user | experienced relic and inland hunters | A poor match wastes features or creates avoidable limitations. |
| Strongest feature | fast response, boost/process choices and ergonomic balance | The primary reason to choose this model. |
| Main caveat | older EMI-sensitive platform | The compromise to accept before ordering. |

Decision analysis
What actually changes the purchase
F75 provides Discrimination, Motion All Metal and Static All Metal operation, 0–99 ID, FastGrab automatic ground balance with manual override and an Fe3O4 mineralization bar.
The 13 kHz frequency is a practical relic/coin compromise. DST reduces background noise at high sensitivity, while frequency shift helps EMI. Neither feature turns it into simultaneous multi-frequency.
Four AA batteries can exceed 40 hours under documented conditions. The roughly 3.5 lb chassis is well balanced, but the non-waterproof housing is the decisive limitation against newer sealed platforms.
