Description
Building on the strengths of the Geode, the world's most popular engineering seismograph, the GeodeFlex delivers a modernized 24-channel acquisition platform engineered for the way field crews work today.
Control the system from any device through the browser-based GeodeFlex Web App (Core bundle), or use the GeodeFlex Web App on a connected laptop (Economy bundle) on a modernized acquisition software suite. The GeodeFlex runs on two integrated field-swappable batteries, with USB-C PD charging. Capture cleaner data with a modern 24-bit, sigma-delta acquisition path delivering up to 32 kHz sampling per channel and up to 13.8 kHz bandwidth.
For passive or monitoring surveys, the Core bundle's integrated Linux controller records continuous GPS-disciplined data autonomously. For active-source work, hardwired triggering keeps the system simple and reliable on day one.
Both bundles are compatible with the same legacy spread and trigger cables as the Geode.

Features & Benefits
Built for modern field crews
Use any screen you wantControl the system from any modern device, PC, tablet, or phone, using the GeodeFlex Web App and Wi-Fi connection.
Fewer cablesInternal batteries and a Wi-Fi connection to the controller mean fewer cables to carry and higher reliability.
Internal batteries with USB chargingUSB-C PD charging of internal batteries using chargers or external batteries you already own. No more 12V batteries in the field.
Geometrics quality data24-bit simultaneous sampling up to 32 kHz, 13.8 kHz bandwidth at -3 dB, and high dynamic range.
Legacy compatible24 analog channels, fully compatible with standard legacy Geode spread cables and triggers.
Integrated timingBuilt-in GPS provides microsecond time sync, eliminating external synchronization boxes.
Stand-alone autonomous recordingAn integrated Linux controller enables GPS time-synchronized recording without external devices for passive and monitoring surveys.
Rugged housingEngineered for extreme field conditions. Shock resistant, IP-55+ weatherproof rating for dust and water ingress.
Software includedModernized acquisition software with improved QC features and SeisImager/2D Lite included.
Proven reliabilityIncludes the 3-year warranty that made the Geode the industry standard.
