Sparkers

Geo-Source 800

Maintenance free negative discharge sparker especially designed for water depths up to 5,000 m.

Description


INNOVATIVE PRESERVING ELECTRODE MODE

The Geo-Source 800 is designed for operation with the Geo-Spark 6kJ or the 2kJ Pulsed Power Supply with extension using the “Preserving Electrode Mode”. This patented concept consists of using a NEGATIVE electric discharge pulse, instead of a positive electric discharge pulse.

Note that working with a negative pulse is NOT the same thing as reversing the polarity of an antique power supply, which is generating a positive pulse.

MAINTENANCE FREE ELECTRODES 5 YEAR GUARANTEE

The Preserving Electrode Mode reduces the tip wear to practically zero. You can shoot day after day, week after week, month after month with practically NO tip maintenance.

OPTIMUM ACOUSTIC REPEATABILITY

Zero tip wear is essential for the repeatability of the acoustic pulse, which depends largely on a constant, unaltered electrode surface.

CONTROL OF THE SPARKER PARAMETERS

The electrode modules are evenly spaced in a planar array of 1.00 m x 2.00 m. This geometry not only enhances the downward projection of the acoustic energy, but also reduces the primary pulse length, since all tips are perfectly in phase electrode. Each tip has an exposed tip surface of 1.4 mm, suitable for maximum 10 J/tip. Four individually powered electrode modules of 200 tips each allow to distribute the energy over 200, 400, 600 or 800 tips.
