Geode Exploration Seismograph,
- Configurations: 8, 12, 16, or 24 channels in weatherproof field- deployable Geode module. Geode is operated from either Windows XP/7-based laptop or by Geometrics’ ruggedized StrataVisor NZ field computer/seismograph. Basic operating software controls one Geode. It can also be optionally expanded to control multiple Geodes, as well as do marine surveying, continuous recording, GPS synchronization, and seismic surveillance.
