Silva Compass 4 Militaire - 6400/360

Silva Expedition 4 Militaire Compass (6400/360)

The Silva Expedition 4 Militaire is a high‑performance navigation instrument designed for military, tactical and outdoor use. Its compact size, durable construction and dual graduation system make it an ideal companion for field operations, long‑range scouting missions, and advanced map reading.

Key Features

• Dual Graduation: The compass offers a 360° degree scale alongside a 6400 mils (mil) scale. This dual system allows users to switch seamlessly between the metric and imperial systems, facilitating rapid alignment with maps that use either measurement.
• High‑Precision Needle: A lightweight yet robust needle provides clear, stable readings even in windy or uneven terrain. The needle is calibrated for minimal drift, ensuring accurate bearings over long distances.
• Transparent Baseplate: The baseplate is made from a durable, transparent material that allows the user to read the map directly beneath the compass without obstruction. This feature enhances speed and accuracy during rapid navigation tasks.
• Integrated Lanyard: A built‑in lanyard attachment point keeps the compass secure on the user's belt or pack, preventing loss in high‑mobility situations.
• Weather‑Resistant Construction: The device is engineered to withstand harsh environmental conditions. Its sealed housing protects against moisture, dust, and temperature extremes commonly encountered in field operations.

Design & Build Quality

The Silva Expedition 4 Militaire boasts a lightweight yet robust design. Its body is constructed from high‑strength polymer that resists impact and abrasion. The baseplate’s transparent surface is scratch‑resistant, ensuring long‑term clarity for map reading. The overall dimensions are compact enough to fit comfortably in a tactical pouch while still providing ample space for the dual scales.

Operational Use Cases

• Military Navigation: Ideal for army units, special forces, and reconnaissance teams that require rapid bearing calculations on the field. The mil scale aligns with standard military maps (1:25k, 1:40k, 1:50k), enabling precise navigation over varied terrain.
• Tactical Scouting: Scouts can quickly determine bearings to objectives or waypoints using the 360° degree scale, which is familiar to most field personnel.
• Advanced Map Reading: The transparent baseplate allows for direct overlay of the compass on topographic maps, facilitating detailed contour analysis and route planning.
• Outdoor Exploration & Hiking: While designed for military use, the compass’s durability and dual scales make it a reliable tool for seasoned hikers, mountaineers, and adventure travelers who need dependable navigation aids.
