Quick Answer: The best lightweight metal detector in 2026 is the XP Deus II WS6 Master (~$799) — a fully wireless, multi-frequency machine that weighs just 750 grams (1.65 lb) with its 9-inch coil, over 30% lighter than most competing machines, per XP. On a budget, the Fisher F22 (about $229, 2.3 lb / 1.04 kg) is the lightest detector under $250, and the Garrett ACE 200 ($179.95, 2.75 lb / 1.25 kg) is the lightest machine with a numeric target ID. If waterproofing matters as much as weight, the Nokta Simplex Ultra (about $299, 1.2 kg / 2.6 lb) holds an IP68 5 m (16 ft) rating in a sealed one-piece build with nothing extra to carry.

A metal detector’s weight on paper is almost never the number that matters. What matters is how it feels after two hours held out in front of you, arm extended, sweeping side to side — and that’s where a few hundred extra grams gets magnified by simple leverage into real wrist, shoulder, and lower-back fatigue by the end of a session. This guide ranks machines specifically for that problem: lowest swing weight, best weight distribution, and the shaft designs that take load off your joints rather than raw spec-sheet numbers that don’t reflect how a detector actually feels in hand.

1. XP Deus II WS6 Master — Lightest Overall, Fully Wireless

XP Deus II WS6 Master

Lightest overall, fully wireless · ~$799
  • 750 grams (1.65 lb) with its 9-inch coil — XP's own published weight, marketed as the lightest metal detector in the world.
  • Fully wireless: coil, control puck, and headphones all talk over XP's radio protocol, so there's no cable and no hip-mounted control box to carry.
  • FMF simultaneous multi-frequency detection with the fastest recovery speed in XP's lineup.
  • Waterproof to 20 m — doubles as a serious diving detector, not just a splash-resistant one.

The Deus II earns the top spot here on a genuinely engineering-driven number, not a rounding trick: removing the control-box-and-cable architecture that every wired detector carries is worth far more than trimming plastic from a housing. At 750 g it weighs almost half what most flagship-tier detectors do, and unlike most lightweight machines it doesn’t trade away performance to get there — its multi-frequency recovery speed is among the fastest XP has built. The tradeoff is price and a menu system with real depth to learn. If $799 is out of reach but you still want XP’s wireless weight advantage, see pick #2 below. (Curious how the Deus II stacks up against XP’s own lineup and Garrett or Minelab’s flagships? Our best XP guide and the Garrett vs Minelab comparison cover the rest of that field.)

2. XP ORX — Lightest Wireless on a Mid-Tier Budget

XP ORX

Lightest wireless on a mid-tier budget · ~$599-799
  • 1 lb 14 oz (0.85 kg) — light enough to cut real fatigue on long prospecting hikes, per XP's published weight.
  • Shares the Deus II's wireless architecture and coil ecosystem at roughly a third less cost.
  • Single selectable frequency instead of simultaneous multi-frequency — the main spec you give up for the price.
  • Coil waterproof to 6 m, but the remote carries no published waterproof rating of its own.

The ORX is the detector to buy if the Deus II’s weight advantage is what sold you, but its price didn’t. It keeps XP’s defining feature — no cable, no control box, hot-swappable coils shared with the Deus II — and still comes in well under a kilogram. You trade simultaneous multi-frequency for a single selectable frequency, which matters more to gold prospectors chasing tiny low-conductivity targets than to a park-and-field coin hunter. For most buyers choosing this guide for arm fatigue specifically, that’s a trade worth making. Read our full XP ORX review for current pricing and the remote’s real waterproofing gap — this table previously listed the control box as “splash-proof,” which overstated a rating XP never actually published for it.

3. Fisher F22 — Lightest Detector Under $250

Fisher F22

Lightest detector under $250 · ~$229
  • About 2.3 lb (1.04 kg) — the lightest wired, boxed detector in this lineup.
  • 7.69 kHz single frequency with auto ground balance, four search modes, and Fe-Tone adjustable iron audio.
  • Weatherproof build (IP54) with a 9-inch coil, five-year limited warranty.

The F22 wins the budget-lightweight spot by a clear margin: at roughly 1.04 kg it undercuts the Garrett ACE 200 by about 200 g while costing $50 more, and it’s the lightest machine here that still runs on a conventional shaft-and-control-box layout rather than XP’s wireless design. Fisher’s own 5-year warranty — longer than Garrett’s or Nokta’s 3-year terms — is worth factoring in if you plan to keep this as a long-term light-duty machine rather than a stepping stone. See our full Fisher F22 review for the real waterproofing breakdown — the coil is submersible, the control box is not. For buyers weighing the whole Fisher range by role rather than weight alone, our best Fisher metal detectors guide ranks the F22 against the F44 and F75.

4. Nokta Simplex Ultra — Lightest Fully Waterproof Sealed Build

Nokta Simplex Ultra

Lightest fully waterproof sealed build · ~$299
  • 1.2 kg (2.6 lb) in a one-piece sealed housing — no separate control box bolted to the shaft.
  • IP68 submersible to 5 m (16 ft), the same rating Nokta puts on its $999 flagship Legend 2.
  • 11 kHz single frequency, 99-segment target ID, built-in low-latency Bluetooth headphone support.

If you want light weight and full submersible waterproofing in the same machine, the Simplex Ultra is the pick — its sealed one-piece design means there’s no separate hip-mounted box adding weight or a loose cable to snag, and at 1.2 kg it’s still lighter than most competing detectors with a 5 m rating. It gives up the Deus II’s and ORX’s wireless-only architecture (it has one cable-free build already, so there’s nothing to add), but it undercuts both on price by a wide margin. Our full Nokta Simplex Ultra review covers the rest of its spec sheet in detail.

5. Garrett ACE 200 — Lightest With a Numeric Target ID

Garrett ACE 200

Lightest with a numeric target ID · ~$179.95
  • 2.75 lb (1.25 kg) — the lightest detector in this guide that still reads a 0-99 numeric target ID.
  • 6.5 kHz fixed frequency, three preset search modes, submersible coil.
  • Breaks into three pieces for transport, four AA batteries, 3-year parts-and-labour warranty.

The ACE 200 is roughly 200 g heavier than the F22, but for a lot of buyers that’s a fair trade for a numeric target ID, Garrett’s three-year warranty, and the biggest support community in the hobby. It’s also the cheapest machine in this guide by a wide margin. If budget is the deciding factor ahead of the last few hundred grams, our best cheap metal detector guide covers the full field under $200, and our best metal detectors for beginners guide covers the $250-$400 tier if you decide the extra weight of a mid-range machine is worth the depth and waterproofing it adds.

Why weight matters more than the spec sheet suggests

A metal detector is held out and away from your body for hours at a time — unlike most tools, the weight isn’t resting against you, it’s suspended at the end of a lever arm formed by your extended arm and the shaft. That leverage is why a detector that’s a few hundred grams heavier doesn’t just feel “a little heavier”; it multiplies the strain on your wrist, shoulder, and lower back by the end of a long session. A 2023 IEEE Access study on handheld mine-detector ergonomics — a different application, but the same physical act of sweeping a handheld detector for hours — found that adding forearm support cut upper-arm muscle exertion (measured via EMG) by as much as 66% during extended sweeping, which is the same physics at work whether the detector is finding mines or coins. XP built its entire lineup around the other half of that equation: its own published figures put the Deus II at 750 g, over 30% lighter than typical competing detectors, by removing the cable-and-control-box architecture rather than by trimming plastic.

How to choose a lightweight detector

The bottom line

For most buyers who care about weight above all else, the XP Deus II WS6 Master at ~$799 is the lightest serious detector you can buy at 750 g, and it doesn’t trade away performance to get there. If that price is out of reach, the XP ORX keeps the same wireless weight advantage for less, the Fisher F22 is the lightest machine under $250, and the Garrett ACE 200 is the lightest option that still gives you a numeric target ID at the lowest price in this guide. Whichever you pick, our metal detector settings guide and ground balance guide help you get the most from a lighter, simpler machine once it’s in your hands.
