XP MI-6 and MI-4 Pinpointer Flat Rubber Washer Replacement Part

The XP MI-6 and MI-4 pinpointer flat rubber washer is a replacement seal component designed to maintain waterproof integrity on XP's MI-series pinpointers. MI-6 and MI-4 owners working wet ground, surf zones, or muddy farm fields need reliable seals to prevent moisture intrusion at the battery compartment. This rubber washer sits between the end cap and housing, forming a compression seal that keeps water out during submersion. Replacing worn or compressed washers before a hunt prevents field failures and extends pinpointer service life.

What's Included with the XP Flat Rubber Washer

• One flat rubber washer for XP MI-6 and MI-4 pinpointers

Why XP MI-6 and MI-4 Owners Keep Spare Washers

• Prevents moisture intrusion: a fresh seal maintains waterproof integrity after hundreds of beach or creek hunts where sand and grit compress the original washer.
• Field-replaceable: swap the washer in minutes with no tools beyond the end cap threads, restoring factory seal performance without sending the unit for service.
• Extends pinpointer lifespan: replacing the washer before it fails prevents corrosion damage to internal electronics, a common failure mode on heavily used MI-series units.
• Low-cost insurance: keeping spares in your dig pouch prevents a hunt-ending seal failure mid-session. Our metal detector parts & accessories catalog carries other MI-series consumables for field maintenance.
• Maintains peak field-readiness for tracking probes evaluated in our comprehensive guide to the best pinpointers for metal detecting.

Seal Maintenance for Waterproof Pinpointers

Rubber seals on waterproof pinpointers compress over time from repeated battery changes and exposure to saltwater, sand, and temperature swings. The MI-6 and MI-4 use a flat washer design where the end cap threads down against the rubber to form a watertight seal. When the washer loses elasticity, water seeps past the threads during submersion. We inspect the washer periodically or after any hunt where the pinpointer took a hard impact. A compressed washer shows permanent deformation and won't spring back when removed. Replacing it before the next wet hunt takes two minutes and helps prevent a costly corrosion failure.
