The SKYWATCH® GEOS N°11 is specially designed for intensive use in harsh environments.
Multi-purpose, accurate and equipped with large memory capacities with the ability of real time data transfer, the Geos 11 and its accessories are particularly well adapted for numerous activities, for example:
• Agriculture; control of wind speed and direction before using sprayed chemicals.
• Agri-foodstuff; control of storage environment (temperature, humidity).
• Automobile; high-performance engine mechanics (density altitude).
• Aviation; reading of the Flight Level, height, finesse, pressure, altitude, altitude variation, etc..
• Rappelling; check the height when rappelling down.
• HVAC; air flows and temperature measurements.
• Sporting events; control of weather conditions during meetings, contests validation.
• Trekking; recording of extreme conditions (mountains, deserts, polar spots), warning of sudden weather changes, wind chill indication.
• Civil engineering; security on sites, labor working conditions.
• Geology; altitude and stratum measurement.
• Military; heat stroke prevention, long range shooters, skydiving, artillery, weather conditions checking in case of chemical attacks.
• Firefighters; managing the risk of forest fire propagation (wind speed and direction).
• Reptiles; control and maintenance of livable conditions (temperature and humidity).
• Rescue teams; evaluation of weather conditions for rescue and survival operations (coast guards, air rescue, etc.).
• Science; meteorology, environment, aerodynamic, etc.
• Sports and leisure; mountain bikes, climbing, alpinism, hiking, bow shooting, fishing, golf, scale models, kites, etc..
• Free flight; hang gliding, paragliding, skydiving, balloon, base jump, wing flight.
• Volcanology; crater height measurement, risk evaluation of gas emanation, etc.
