The Gecko Blast is a compact all-in-one triaxial (East-West, North-South, Up-Down) velocity sensor and data logger. The internal 4.5Hz geophones allow recording of peak amplitudes of almost 700mm/s, and frequencies up to 1600Hz.
Data reports and analysis can be processed from the SD card on any PC. Installation is simple: bolt it down to rock or concrete using an anchored rod using the hole through the middle of the body, or replace the levelling feet with spikes to push it into soil. Record for days, weeks, or months – never miss a thing. Alarm outputs can activate an optional local beacon, or transmit data in real time to a remote computer via Ethernet, WiFi or cellular modem.
The standard LCD and keypad offers full configuration without the need for a PC in the field. The Gecko Blast draws around 1W of power, so a lead-acid battery of similar size to a car battery will provide about a month of backup power.
