Applied Acoustics - Model Dura-Spark L80 -Sound Source, Sparker
The Dura-Spark L80 has been designed to provide a lightweight stable, repeatable sound source for sub-bottom geophysical surveys. The long-life, durable electrodes produce a consistent pulse signature and keep operational maintenance to a minimum. This provides increased survey efficiency and equipment reliability as the sparker tips rarely need replacement.
- Long life, durable electrodes
- Pulse stability
- High resolution sub-bottom data, up to 15cms
- Compact, lightweight.
- Single low loss cable
- High and Ultra-High Resolution coastal, river, canal or estuary geophysical surveys
- Hydrographic sediment investigation
- Cable and pipeline route survey
- Single and multi-channel acquisition
- Water depths of 5m to 200m
