- NAVIGATION & SURVEYING
+Offline maps show the surrounding terrain. GNSS diagnostics help assess positioning quality; track recording preserves your path. KML routes provide elevation and waypoint context.
+COMMUNICATION & COORDINATION
+Choose a network, keep your contacts and check message delivery. Pair a team nearby using ESP-NOW, then share positions, assembly points and messages over LoRa.
+FIELD TOOLS & CONNECTIONS
+Browse Reticulum Micron services through Nomad Network. Use MQTT when a gateway is available, and prepare map regions and routes with Trail Mate Center.
+Communication
-- Write messages on the device, retry failed sends from the message bubble, and keep team conversations - separate from ordinary channel traffic. -

- BEFORE DEPARTURE
+Choose the exact board and radio variant, flash its firmware and check the available peripherals. Pager SX1262 and LR1121 use separate builds.
Load your map region, import KML routes and install the language packs you need. Prepare map regions and route corridors with Trail Mate Center.
Trail Mate Center ↗Choose a protocol and compatible radio settings. Check contacts and GNSS, pair the team nearby, and exchange a test message before departure.
Setup guide: file paths, hardware controls and device-specific instructions ↗
+Field Utilities
-- Use signal scanning, SSTV receive, USB data exchange, and track views when you need to inspect the - environment or recover data. -

- WHY A SCIENTIFIC CALCULATOR?
+The scientific calculator supports outdoor surveying: estimate height differences, convert slope distances to horizontal distances, and calculate slope angles or gradients from your measurements.
+At a horizontal distance of 30 m and an elevation angle of 35°, the height above the observation level is 30 × tan(35°) ≈ 21.01 m.
For tree height, add instrument height when the tree base and your footing are level; otherwise account for the ground elevation difference.
A straight 100 m segment at 20° has a horizontal distance of 100 × cos(20°) ≈ 93.97 m and a rise of 100 × sin(20°) ≈ 34.20 m.
Calculate curved routes or changing slopes segment by segment.
A 12 m rise over a 40 m horizontal run gives atan(12 ÷ 40) ≈ 16.70°, or a 30% grade. Degrees and percent grade are different units.
Supports sin, cos, tan, inverse trigonometric functions, powers, roots and logarithms, with DEG/RAD modes. Enter measured angles and distances; the calculator does not measure them.
