Killer B Thresher Submersible Headphones for Minelab Equinox Series, Manticore, X-TERRA Pro and Elite

The Killer B Thresher Submersible Headphones give Minelab Equinox, Manticore, and X-TERRA owners a wired audio solution rated to 200 feet, putting the headphones well beyond the 16-foot waterproofing limit of the detectors themselves. Built with Minelab-approved Holin connectors and oversized speaker elements, the Thresher connects directly to the detector's headphone jack or through the WM08 module and delivers full, clear audio from a dry beach session to a snorkel or dive hunt. Designed and assembled in the USA and backed by a 2-year manufacturer warranty, the Thresher is one of the few wired submersible headphones purpose-built for this detector family.

What's Included

• Killer B Thresher Submersible Headphones with Minelab-approved Holin connector

Why Equinox and Manticore Owners Reach for the Thresher

• Standard headphones fail in surf. Repeated salt water exposure kills most over-ear headphones within a season. The Thresher's 200-foot submersion rating lets you work wet sand, break zones, and shallow dives without managing your audio gear as a separate fragile item.
• Wired audio has zero latency. Every tone corresponds precisely to your coil position. At trashy beach sites with tight target separation, a half-swing of wireless lag causes mis-located signals; a direct wired connection eliminates that variable entirely.
• Holin connectors seal out water at the plug. Generic aftermarket connectors allow water ingress during submersion. The Minelab-approved Holin connectors on the Thresher hold a sealed connection from machine to driver in the same conditions the Equinox and Manticore are rated for.
• Oversized speaker elements deliver richer tones at lower volume. Lower volume reduces listening fatigue on long sessions, and the Thresher's oversized elements drive faint signals from thin gold and small silver clearly without pushing the detector's audio output to its limit.

Where the Thresher Excels

Surf Zone and Wet Sand Beach Hunting

The Equinox family handles salt water. The Thresher matches that, with a 200-foot submersion rating that covers anything you encounter wading and well past it. Standard headphone wiring and earcup seals fail quickly in surf; the Thresher holds up through full sessions in the wash. On a windy beach, a sealed over-ear headphone also blocks ambient noise more effectively than the speaker, so you catch faint mid-tone signals from thin gold before you've swung past the hole. For settings guidance on the Equinox family at the beach, see our beach detecting guide.

Snorkeling and Shallow Diving

The Manticore and X-TERRA Pro, Elite, and Expedition all handle full submersion. The Thresher's 200-foot rating covers every depth these machines can reach and well beyond. Wired audio is the practical choice here: no wireless module to manage separately, no pairing, and no risk of a module flooding independently. Your audio is live the moment the detector is on.
