The most powerful boat towed metal detector for ferrous metals.
A high performance, micro-processor driven system, the Proton 4 is the ultimate detector for ferrous metals such as iron and steel. The Proton 4 is in use by military, law enforcement, commercial, and salvage divers world wide. It's extremely large detection area make this detector ideal for both commercial operations and professional treasure hunters.
The claim-to-fame of this marine magnetometer is it's rugged construction, ease of operation and the number of available options. The Proton 4 has one gamma sensitivity, the maximum practical sensitivity for a towed magnetometer. It's maximum range capability of 1500 feet on each side (3000 feet total swath for a very large target) let's you cover a wide area quickly and completely. The detection range is unaffected by the medium between the metal detector and the metal target. Performance does not change whether detecting through air, water, silt, sand, or solid coral.
The Proton 4 system includes tow fish with 150 feet of cable, and a top-side control unit. The control unit features easy to read LCD display, audio alarm, and variable sensitivity switch (for pinpointing targets). An optional built-in printer is available which gives hard copy of mag readouts and Loran or GPS position. Options include 300 foot tow cable, UA-2 altimeter, RS232 data output, data collection and storage software, 500 and 1000' depth rated versions. The system is powered by a 12 volt battery with a total power consumption of only 40 watts.
Key Features of the Proton 4:
Commercial grade construction, one gamma sensitivity, extremely large detection area, faster towing speeds than Pulse systems, and ability to make permanent record of readings.
