Minelab PRO-FIND 40 Waterproof Pinpointer with Black Security Lanyard

The Pro-Find 40 is compatible with all metal detectors regardless of brand or technology. Minelab designed the Pro-Find 40 as a universal pinpointer, so it works with Garrett, Nokta, XP, Fisher, and any other detector you own. The DIF technology built into the Pro-Find 40 reduces interference when the pinpointer is switched off, which is particularly useful when you're running it alongside VLF detectors like the Equinox or Vanquish series. You can clip it to your belt between targets without worrying about phantom signals on your detector.

The Pro-Find 40 is fully waterproof to 10 feet, not just splash-resistant. You can submerge the entire unit in rivers, lakes, and saltwater surf without damaging the electronics. The 10-foot depth rating covers wet-sand hunting, shallow wading, and most freshwater creek sites where coins and jewelry accumulate. The waterproof seal extends the full length of the pinpointer, so you don't need to worry about water entering through the battery compartment or speaker grille. For deeper diving or scuba recovery work beyond 10 feet, you would need a pinpointer rated for greater depths.

Ferrous Tone ID gives the Pro-Find 40 two distinct audio responses based on the target's ferrous content. When you pinpoint a non-ferrous target like a coin, ring, or aluminum pull tab, you hear one tone. When you pinpoint a ferrous target like an iron nail, bottle cap, or steel xxxx , you hear a different tone. This feature helps you decide if to dig or move on before you invest time in a trashy target. The tone distinction is most useful in parks and old homesites where iron contamination is heavy. Keep in mind that Ferrous Tone ID identifies ferrous versus non-ferrous, not specific metals, so aluminum and gold both trigger the non-ferrous tone.

The Pro-Find 40 has five sensitivity levels you adjust by pressing the sensitivity button on the handle. Level one is the lowest sensitivity, useful in trashy sites or highly mineralized ground where you want to reduce false signals. Level five is the highest sensitivity, giving you maximum depth in clean soil or dry sand. You cycle through the levels by pressing the button repeatedly, and the pinpointer indicates the current level with a series of beeps or vibrations. Most detectorists start at level three and adjust up or down based on ground conditions. In wet saltwater sand, dropping to level two or three reduces ground noise without sacrificing much depth.

The lost alarm on the Pro-Find 40 activates automatically after a period of inactivity. If you set the pinpointer down at the edge of a hole or in tall grass and forget it, the unit emits a loud beeping sound to help you locate it. The bright red handgrip also makes the Pro-Find 40 easier to spot visually when you're scanning the ground. The lost alarm is particularly useful in low-light conditions at dawn or dusk, or when you're working a large area and moving between multiple holes. You deactivate the alarm by pressing any button on the pinpointer. The feature runs on the same 9V battery, so it doesn't require a separate power source.

Minelab rates the Pro-Find 40 at 20 hours of nominal battery life on a single 9V alkaline battery. Actual runtime depends on how you use the pinpointer. Running at maximum sensitivity (level five) with both audio and vibration enabled drains the battery faster than running at lower sensitivity with audio only. Cold weather also reduces alkaline battery performance, so you may see shorter runtime in winter conditions. Most detectorists carry a spare 9V battery in their pouch or pack, especially on all-day hunts. The battery compartment is easy to access, and swapping a fresh battery takes less than a minute. For longer runtime, lithium 9V batteries offer better performance in cold weather and extended shelf life.

The Pro-Find 40 does not have a headphone jack, so you cannot connect wired headphones directly to the unit. The pinpointer relies on its built-in speaker and vibration motor for target indication. Most detectorists run pinpointers without headphones because pinpointing happens at close range where the speaker is loud enough to hear clearly. The vibration mode on the Pro-Find 40 serves as a silent alternative to audio when you're hunting in noise-sensitive areas or want to reduce distraction. If you need a pinpointer with headphone capability, other models in the Minelab pinpointer lineup or competing brands offer that feature, though most field users find the Pro-Find 40's speaker and vibration sufficient for target recovery.

Yes, the Pro-Find 40 lets you toggle audio and vibration independently, so you can run audio-only, vibration-only, or both simultaneously. Audio-only mode is quieter in public parks where beeping draws attention, and it conserves battery compared to running both feedback modes. Vibration-only mode works in loud environments like surf breaks or near heavy equipment where audio is difficult to hear, and it's useful for detectorists with hearing impairments. Both modes together provide redundant confirmation in challenging conditions (wind noise, breaking waves, dense brush). The LED tip light operates in all modes, illuminating the hole regardless of your audio and vibration settings.

This bundle includes the Minelab Pro-Find 40 pinpointer, the manufacturer's belt holster, the manufacturer's lanyard, multi-language instructions, and an additional Serious Detecting black security lanyard. The standard Pro-Find 40 package from Minelab includes only the pinpointer, holster, one lanyard, and instructions. The extra Serious Detecting lanyard provides a backup attachment point or a longer tether for surf hunting, where a dropped pinpointer can wash out with the tide. The holster clips to a belt or detector harness for quick access during recovery, and the lanyards attach to a belt loop or vest D-ring to prevent loss in dense cover or moving water.

The Minelab Pro-Find 40 and Garrett Pro-Pointer AT are both waterproof pinpointers, but not to the same depth: Minelab rates the Pro-Find 40 to 10 ft (3 m) and Garrett currently rates the Pro-Pointer AT to 20 ft (6 m) with an IP68 rating. They also differ in tone ID and interference handling. Both have adjustable sensitivity from the button: five levels on the Pro-Find 40, three on the Pro-Pointer AT plus a Fast Retune press. The Pro-Find 40's ferrous tone ID differentiates iron from non-ferrous targets, while the AT has no ferrous tone ID. The Pro-Find 40's DIF technology reduces interference from nearby detectors, a feature the AT lacks. Both include a built-in flashlight, run on a 9 V battery and ship with a holster. Garrett rates the Pro-Pointer AT at about 30 hours on an alkaline 9 V (16 hours carbon-zinc, 8 hours on a rechargeable); Minelab rates the Pro-Find 40 at up to 20 hours on its 9 V without stating the battery type. Detectorists who hunt with Minelab multi-frequency machines benefit most from the Pro-Find 40's DIF and tone ID; anyone who puts the probe under more than a few feet of water should pick the AT.
