Greensea demonstrates Bayonet 250 surf-zone UXO survey
Greensea demonstrated a Bayonet 250 carrying a White River Technology APEX sensor sled and using OPENSEA to survey buried munitions in the surf zone.
Why it matters
The test provides exact Bayonet 250 configuration and operating-condition evidence across a measured surf-zone survey, with the APEX sensor and OPENSEA roles kept explicit.

Evidence notes
- The eight-day survey covered 18 square kilometres in water up to 10 feet deep and waves of four to six feet.
- Bayonet 250 towed a sled carrying White River Technology's marine APEX electromagnetic-classification array integrated with OPENSEA.
- The configuration identified buried targets by depth and signal signature, with detection reported to depths of up to three metres depending on material.
