Description
The Equinox and the Manticore are waterproof machines. The question is whether your ears can follow them in. The DetectorPro Gray Ghost Amphibian II for Minelab Manticore and Equinox is one set of full over-ear headphones for both jobs: 100% waterproof, submersible to 200 ft (61 m), and wired for the waterproof headphone connector these machines share, so land, wading, and full submersion are all the same hunt.
At a glance
The Gray Ghost Amphibian II (Manticore and Equinox version) is a wired, fully submersible over-ear headphone built in the USA by DetectorPro. It fits the Minelab Manticore and the Equinox series (600, 700, 800, and 900), blocks up to 24 dB of ambient noise, runs a heavy-duty 48 in (122 cm) coiled cable with waterproof plug, and folds for the gear bag. No batteries, no pairing, no charge anxiety.
Why this version, stated plainly
DetectorPro's own product page covers BOTH the Manticore and the Equinox with this one version, yet many dealer listings bury the Manticore in a parenthetical or sell every connector version from a single page where the wrong pick is one dropdown away. This listing is one machine family, one connector, no ambiguity. The other Amphibian II versions are wired differently, so buy by machine: CTX 3030, XP DEUS II, and Nokta Legend/Simplex/Kruzer/Anfibio. Note: some dealers also list X-Terra or Score compatibility for this version; DetectorPro's page names the Manticore and Equinox, so that is what we will promise.
What the spec sheet means in the water
| 100% waterproof, submersible to 200 ft (61 m) | Well past the machines' own depth ratings. The headphones will never be the limit. |
| Sound-blocking muffs, up to 24 dB | Cuts wind and surf noise so the Manticore's faint deep tones survive the beach. |
| Heavy-duty 48 in (122 cm) coiled cable, waterproof plug | Slack to swing, recoils out of the digging zone. |
| Solid-state speakers, louder second-gen internals | DetectorPro redesigned the Amphibian II internals for louder volume than the original. |
| No screws, no wire frame, no rust | Salt water is the design brief, not the enemy. |
| Thick polymer cushions, full-ear surround | All-day comfort with a real acoustic seal. |
| Foldable, built in the USA | Collapses for compact carry and storage. |
| Warranty | 2-year limited warranty against defects in materials and workmanship |
Wired on purpose
Bluetooth does not work underwater, and a headphone battery that dies at hour six ends the hunt early. The Amphibian II is a sealed, passive, wired design: nothing to charge, nothing to pair, nothing to flood. Plug into the waterproof connector and detect. When a target is located in the wet stuff, the DetectorPro Land or Sea pinpointer is the same-brand recovery partner, waterproof to 20 ft (6 m).
