Fisher F22 settings
Fisher F22 settings for wet salt sand on the tide line
Quick answer
Detecting on wet salt sand on the tide line, the Fisher F22 wants low sensitivity, slow to medium recovery speed and the stock 9 inch coil. Poor fit for this ground. A single-frequency machine like the Fisher F22 fights wet salt sand on the tide line.
A single-frequency machine like the Fisher F22 fights wet salt sand on the tide line. Salt water is conductive, and a single-frequency VLF machine reads that conductivity as one huge overlapping signal. You can make the Fisher F22 run quietly by dropping sensitivity a long way, but what you are really doing is throwing away the depth you came for. This is the one situation where the machine, not the operator, is the limit.

What is wet salt sand on the tide line actually like to detect?
The ground that separates machines. Wet salt sand is conductive, and a single-frequency VLF machine reads that conductivity as one enormous target, which is exactly what simultaneous multi-frequency exists to cancel.
The targets you are realistically there for are gold rings, chains and coins moved by the tide. That, plus how mineralised the ground is, is what decides every setting below.
What should I set my Fisher F22 to on wet salt sand on the tide line?
On wet salt sand on the tide line the Fisher F22 wants low sensitivity, slow to medium recovery speed and the stock 9 inch coil.
| Setting | Starting point | Why |
|---|---|---|
| Sensitivity | Low, roughly the bottom third of the range | Running hot in difficult ground produces noise, and noise hides the faint deep signals you are there for. |
| Discrimination | Minimal, salt beaches hold very little ferrous trash | Rejecting more than you need to costs you targets you would have wanted. |
| Recovery speed | Slow to medium, which buys back depth | Slower processing buys depth where there is nothing crowding the target. |
| Ground balance | Use the machine's beach or salt routine rather than a soil balance | Balanced ground is quieter ground, which makes a faint signal audible. |
| Audio | Multi-tone with a clear iron tone | Tone information is how you judge a target before you commit to digging it. |
| Coil | Stock 9 inch is the right starting point | Coil choice is a coverage and separation trade, matched to the ground. |
| Water | Coil in the water only. The Fisher F22 is weather resistant only, so keep the control box dry | This is the one specification on the page that is absolute. No setting works around it. |
These are starting points, not specifications. Your machine's manual is the authority on what each control does and what range it offers, and the numbers that matter are the ones you get in your own soil. Settings also move between firmware versions.
What can the Fisher F22 realistically do here?
Ground on wet salt sand on the tide line is moderately mineralised, which means depth on a coin-sized target sits in the middle of whatever this machine manages in ideal conditions.
| Target | How it behaves here | What to do about it |
|---|---|---|
| Coin-sized non-ferrous | Reads clearly at moderate depth, less stably deeper | Check it from two directions before digging. A signal that holds from both is worth the hole. |
| Small gold and thin chains | Marginal, and easy to walk over entirely | A smaller coil and less discrimination is how you stop missing these. |
| Large relics and iron-backed targets | Loud, sometimes masked by nearby iron | Usually straightforward. |
| Aluminium trash | Occasional | Easy to live with. |
No manufacturer publishes a depth figure in inches for these machines, and anyone printing one has invented it. Depth varies with target size, orientation, corrosion, moisture and mineralisation, so the only figure worth having is the one you measure yourself.
How to calibrate this to your own ground
- Bury known targets. Bury a coin, a small piece of gold or a thin chain, and a pull tab at measured depths in the ground you actually hunt, and leave them for a few weeks so the soil settles.
- Walk the test bed. Sweep it with the Fisher F22 at the settings above and write down what you get: the reading, how stable it is, and at what depth it disappears.
- Change one thing. Move a single setting, walk the bed again, and record the difference. Changing several at once tells you nothing about which one mattered.
- Write it on the machine. Keep the settings that worked on a card in your pouch. A setup you can reproduce is worth more than one you found once and cannot remember.
What to use on wet salt sand on the tide line instead
If this is ground you hunt often, these machines are built for it. That is not a reason to replace a detector you are otherwise happy with, but it is the honest answer to whether the Fisher F22 belongs here.

We did not test these machines in person and we publish no find claims. Picks are researched from manufacturer specifications and owner manuals, published listing features, waterproof ratings and warranty terms, and the recurring themes in verified owner reviews. We favour the established detector brands because coils, shafts and control boxes have to stay available years after a model is discontinued, and we place every pick in the tier where its price and capability honestly belong.

Frequently asked questions
What sensitivity should I run on the Fisher F22 on wet salt sand on the tide line?
Start at low, roughly the bottom third of the range and work from there. The rule that matters more than the number is that a machine running so hot it chatters is a machine that is hiding faint deep signals in its own noise. Turn it up until it becomes unstable, then come back down a step, and re-check whenever the ground changes.
Can I use the Fisher F22 on wet salt sand on the tide line at all?
Salt water is conductive, and a single-frequency VLF machine reads that conductivity as one huge overlapping signal. You can make the Fisher F22 run quietly by dropping sensitivity a long way, but what you are really doing is throwing away the depth you came for. This is the one situation where the machine, not the operator, is the limit. If this is ground you hunt regularly, the machines listed above are built for it. If it is an occasional trip, work within the limitation and know what you are giving up rather than assuming a setting will fix it.
What coil should I use on wet salt sand on the tide line?
Stock 9 inch is the right starting point. Coil choice changes target separation more than any menu setting, so it is the first thing to reconsider when a site is not producing. Coils are machine-specific and often series-specific, so check the compatibility chart for your own detector before ordering, because a coil that does not fit is an expensive mistake.
Can the Fisher F22 get wet on wet salt sand on the tide line?
Coil in the water only. The Fisher F22 is weather resistant only, so keep the control box dry. This is the one specification on the page that is absolute: sensitivity and discrimination are preferences you can experiment with, and a waterproof rating is not. A waterproof searchcoil and a fully submersible machine are different things, and confusing them is how control boxes die.
Do I need permission to detect on wet salt sand on the tide line?
Almost certainly, and you should assume yes. Get the landowner's permission before detecting on any ground you do not own, in writing where you can. Many public parks and recreation grounds prohibit detecting outright, national parks and protected archaeological sites are off limits in most jurisdictions, and the rules vary by country, state, county and individual parcel. Check before you go.
