Acoustic Pingers/Transponders

Used to mark and relocate equipment and locations underwater, our cost effective acoustic beacons/transponders and receivers/interrogators are available in a wide variety of options to meet any requirement. Our receivers/interrogators can be mounted on subsea vehicles, used from the surface or operated by a diver. With different frequencies, activation methods, and battery life options… we have a solution for any marking and relocation requirement with our pingers/transponders.

RJE International specializes in customization and we can design a pinger/transponder to meet you specific needs. Whether it is an emergency location beacon for your subsea vehicle or towfish, marking equipment moorings, or track divers during training RJE can meet your needs.

SYSTEMS
SEEKER
	Acoustic Subsea Vehicle Relocation System The SEEKER consists of a small but rugged passive pinger receiver used to assist operators of ROVs and AUVs to track acoustic sound sources for 25Khz to 40Khz. In addition, the SEEKER receivers can function as an “acoustic transponder interrogator” and provide accurate range and bearing to targets marked with a line of custom acoustic transponders.

Dive-Trak Pro
	Dive-Trak Pro The next generation of diver marking and relocation equipment, the Dive-Trak Pro provides the operator accurate range and bearing to underwater targets that are marked with a ATT-400 transponder. Dive-Trak Pro Data Sheet (PDF 78K)
ACOUSTIC PINGERS/TRANSPONDERS
ATT-400
	Acoustic Target Transponder The underwater acoustic transponder is small and easy to deploy. When interrogated by the DTI-300, the transponder provides range and bearing up to 750 meters away. With a battery life of up to 6 months, this transponder is ideal for marking equipment and locations in poor visibility. ATT-400 Data Sheet (PDF 78K)
ATT-400/1KM
	Acoustic Target Transponder, 1000M Rated Small and easy to deploy, the ATT-400/1KM provides range and bearing up to 750 meters away when interrogated by the VADR series receives or the DTI-300. With a battery life of up to 6 months, this transponder is ideal for marking equipment and locations. SEEKER Data Sheet (PDF 340K)
ATT-400/6KM
	Acoustic Target Transponder, 6000M Rated Designed for deeper deployments, the ATT-400/1KM provides range and bearing up to 750 meters away when interrogated by the VADR series interrogators. With a battery life of up to 6 months, this transponder is ideal for marking equipment and locations. SEEKER Data Sheet (PDF 340K)
ULB-350
	Low Cost Location Beacon This underwater beacon is a cost effective acoustic pinger used for marking equipment and underwater sites. Ideal for applications where size and weight are an issue. Offers flexible features that allow you to tailor it to your requirement. ULB-350 Data Sheet (PDF 141K)
ULB-362
	Full Ocean Depth Acoustic Location Beacon The ULB-362 is a compact, cost-effective, full ocean depth, underwater emergency location beacon designed for applications where size is critical. Typical applications include use on ROVs, AUVs, ordinance and equipment recoveries. The ULB-362 can be ordered in stainless steel. ULB-362 Data Sheet (PDF 141K)
ULB-362PL
	Underwater Beacon with Power Loss This underwater beacon can be activated by power loss through an external connector. Ideal for ROVs and AUVs. The ULB-362/PL automatically activates when a relay closes on the vehicle due to power loss and can be ordered in stainless steel. ULB-362PL Data Sheet (PDF 141K)
ULB-362TD
	Underwater Beacon with Time Delay This beacon has a time delay option that is custom specified at the time of order. It meets the same standards as the ULB-362 but offers extended operational life with the time delay option. The ULB-362TD can be ordered in stainless steel. ULB-362TD Data Sheet (PDF 141K)
ULB-364
	General Purpose Acoustic Beacon The ULB-364 Series Underwater Location Beacon is a cost-effective acoustic relocation pinger designed for rigorous offshore use. Using off the shelf 9V alkaline or lithium batteries, the ULB-364 is ideal for marking underwater sites or equipment where cost is a factor. ULB-364 Data Sheet (PDF 66K)
ULB-364EL
	Long Life Acoustic Beacon This underwater beacon offers the same features as the ULB-364 with a lower operational life. Longer than the ULB-364, the ULB-364EL can be deployed for up to 18 months. ULB-364EL Data Sheet (PDF 66K)
