Marine SAR Intelligence, Precision in Every Operation.
Engineered for the high-stakes reality of marine search and rescue. Our intelligent app provides the glanceable authority required when seconds decide search outcomes.
Mission Control Interface
Every screen is built for on-water SAR: pattern timers, leg headings, track spacing, and quick calculations at a glance — high contrast, low-light ready, and usable under pressure.
Sector Search
Accurate timing of back to back sector searches with offset coordinates and datum resets.
Mission Preview
app feature demonstration video.
Expanding Search
Cover a large search area with an expanding square search accurately timed with easy heading changes.
Marine-Grade Features
Sector & Expanding Square Search Patterns
Enter your vessel's speed and track spacing — the app calculates every leg, heading, and timing automatically. A built-in timer guides your crew through each circuit so you stay on pattern and cover maximum area with confidence.
Speed, Distance & Time Calculator
Enter any two values and instantly get the third. Eliminate mental arithmetic under pressure — whether you need ETA, required speed, or distance to datum, the answer is one tap away.
Calculate Distance & Bearing to Target Coordinates
Input any latitude and longitude and get an immediate readout of distance and bearing from your current position. Navigate directly to a reported distress location and provide an accurate ETA to mission control.
