Seamap GunLink 1000

GunLink - 1000 is the entry level GunLink solution. With all the improvements GunLink brings of increased sample rates and Enhanced QC software, the GunLink 1000 is targeting smaller configurations and operations on a reduced budget. 		SEAMAP_gunlink1000

Seamap GunLink 2000

The GunLink - 2000 is the Seamap On-Board Gun Controller and Hydrophone Acquisition System. It is expandable to control up to 256 guns and acquire data from up to 512 Near Field Hydrophones with 24 bit resolution at 0.1mS sampling

Seamap GunLink 3000

The GunLink 3000 is the second phase of Seamap's range of new generation hydrophone monitoring and gun control systems. The system provides in-water firing control and sensor timing monitoring of up to 256 standard uns (128 GI guns) and is capable of receiving hydrophone data from up to 512 near field phones. The GunLink 3000 moves the system electronics in to the water allowing it to be mounted close to the gun array, thus reducing umbilical diameters, increasing umbilical lengths and allowing shorter offsets.
