PalliPartners Metal Detector for Adults Waterproof-Professio

The Verdict

Let’s be straight with each other: most metal detectors under $150 are toys dressed up in serious-looking plastic. The PalliPartners Metal Detector for Adults sits at a weird and interesting middle point — it’s not a beginner’s gadget, but it’s also not a $700 Deus. After digging through 220 Amazon ratings (4.4 stars average) and cross-referencing user reports, here’s the real story.

What’s actually in the box

PalliPartners sends you the full kit: the detector pre-assembled in two pieces (shaft and coil), a wired headphone set, a 9V battery, and a foldable digging trowel that’s actually usable, not a flimsy afterthought. The shaft extends from 24 inches to 46 inches, so a 5'2" casual hunter and a 6'4" beachcomber can both swing it comfortably.

The standout spec is the 10-inch waterproof search coil — IP68 rated, meaning it’s fully submersible rather than just splash-resistant. That’s unusual at this price point. The control box itself is not waterproof, so you’re wading, not diving.

How it performs in real dirt

The three discrimination modes (All Metal, Disc, and Tone) work as advertised. In All Metal, you’ll hear everything including bottle caps and rusted nails — which is fine when you’re prospecting for anything. Switch to Disc mode and set the notch to reject iron, and you’ll cut dig time dramatically.

Depth performance is honest: on a buried quarter, users consistently report 8-10 inches in average garden soil. On wet beach sand, expect 6-8 inches before the signal fades. That’s respectable for a coil in this class — not a pulse-induction machine, but solid VLF performance.

The three-tone audio is where this detector earns its keep. Low tone for iron, mid for foil and pull tabs, high for coins and silver. One Amazon reviewer put it well: “I dug 14 targets in two hours and only 3 were junk. The tone breaks saved my back.” That selectivity is the difference between a frustrating afternoon and a productive one.

What buyers consistently praise

Across the 220 ratings, recurring themes emerge:

• The waterproof coil gets people out to new spots. Several reviewers specifically mention hunting in creeks and along shorelines without hesitation. One wrote, “Took it in the river up to my knees, no issues at all.”
• Assembly takes under five minutes. No tools needed — the cam locks and twist collar are genuinely tool-free.
• Battery life is excellent. A single 9V lasts 25-30 hours of actual field use. That’s two solid weekends of hunting.

Where it stumbles

The included headphones are the weakest link. They’re the classic wired over-ear style with thin foam padding, and the cord is about three feet too short — it catches on branches and pulls your head down when you bend to dig. Budget $20 for a decent Bluetooth transmitter and wireless pair if you hunt brushy areas.

Manual ground balance is the other tradeoff. In iron-rich red clay or wet salt sand, you’ll need to re-balance every 15-20 minutes or the detector will chatter with false signals. It’s a learned skill, not a set-and-forget feature. If you’re a total novice, budget a couple of practice sessions in your backyard before hitting the beach.

Who should buy this

• The water-curious hobbyist — if you’ve been eyeing creeks, rivers, or shorelines but didn’t want to risk a cheap detector’s non-waterproof coil, this is your entry point.
• The weekend coin shooter — parks, schoolyards, and old homesteads in moderate soil will yield plenty of targets with the Disc mode.
• The gift-giver — for a parent or grandparent who’s mentioned wanting to try the hobby, this is a genuinely capable starter that won’t frustrate them into quitting.

Skip it if you’re hunting heavily mineralized gold country (you need a dedicated gold machine with automatic ground balance) or if you want a fully submersible unit for actual underwater hunting — this one stops at the control box.

FAQ

Can I use it in saltwater? Yes, for wet sand and shallow wading up to the control box. The coil is fully submersible, but keep the electronics dry. Rinse the shaft and coil with fresh water after salt exposure.

Does it differentiate between metals? Yes. Three-tone audio plus a target ID scale (0-99) gives a numeric readout. It won’t tell you “silver dime” precisely, but you’ll learn the ranges — pull tabs read 40-55, coins read 70-85.

How deep does it actually detect? Realistic field depth: 8-10 inches for coin-sized objects in moderate soil, up to 12 inches for larger targets like cans or horseshoes. Don’t believe anyone promising 15+ inches at this price.

The Verdict

Rating: 4.2/5 — The PalliPartners is a rare find: a sub-$200 detector that respects your time with solid discrimination and a genuinely waterproof coil, without pretending to be something it’s not. The headphones and manual ground balance are real annoyances, but they’re fixable or learnable.

Buy it if you want a dependable, water-ready detector for parks, beaches, and shallow water without dropping $400+.

Skip it if you demand auto-ground balancing or plan to hunt in heavy mineralization — step up to a mid-tier machine instead. For everyone else, this is the best bang-for-buck in its class right now.
