Portable Magnetic Survey Control Box
The DBL15 Portable Magnetic Survey Control Box is an IP67-rated measurement case weighing 1.7 kilograms with dimensions of 215 x 275 x 110 millimeters. The unit operates FGM400/38 tension band probes featuring ±30,000 nanotesla displayed measurement range across nine selectable sensitivity ranges. Internal lithium-ion battery provides approximately 40 hours continuous operation between charges. Probe cables extend to 150 meters length, accommodating deep diving operations and vessel-based deployments at significant distances from support craft.
The FGM400/38 probe measures 35mm housing diameter with 400mm sensor element spacing and operates across ±75,000 nanotesla range with 0.2 nanotesla resolution. Noise performance remains below 40 picotesla per root hertz at 1Hz frequency. The analog pointer instrument displays readings across ±10 scale divisions with 0.075 nanotesla resolution in the 3 nanotesla measurement range. Temperature drift stays below 0.3 nanotesla per Kelvin with ±4 nanotesla linearity specification. Operating temperature spans -20°C to +50°C.
Commercial diving teams deploy the DBL15 Portable Magnetic Survey Control Box for subsea unexploded ordnance location during offshore construction preparatory surveys. Underwater salvage operations use it to detect ferrous components within shipwreck debris fields before recovery equipment deployment. Harbor maintenance divers employ the system for locating lost tools, anchor chains, and metallic infrastructure beneath vessel berthing areas. Geotechnical investigation firms utilize it for borehole magnetic measurements during marine foundation site characterization studies.
Tactical Supply Pakistan provides specialized underwater detection equipment for diving professionals conducting subsurface magnetic anomaly surveys in marine and inland water environments.
Why does the 150-meter cable length capability matter for vessel-based diving operations?
Extended cable reach allows divers to operate beyond vessel magnetic interference zones created by steel hulls, engines, and onboard equipment. Large support vessels generate significant magnetic signatures extending 50-100 meters from the hull centerline. The 150-meter cable permits measurements in magnetically clean water while maintaining hardwired communication and power connections to surface control systems.
