• Fastest sampling at high sensitivity means even small targets can be detected

• Cesium vapor technology provides furthest detection range. highest sensitivity at 0.004 nT/aHz

• New streamlined design improves safety, less chance of snagging on rocks or debris

• Convertable nose or CG tow mechanism, lets you choose survey style, gets fish deeper.

• Flash memory stores all parameters, eliminates need for oh-board reprogramming

• New echo sounder and altimeter shows height above sea bottom and depth in water column in real time

• 2700 m (9000') depth rating lets you use one mag for all surveys

• Easy portability and handling - no winch required- single man operation, 44 lbs with 200 ft cable (without weights or depressor wing), new carrying handle

• Combine two systems for increased coverage– Internal CM-221 Mini-Counter provides multi-sensor data concatenation allowing side by side coverage which maximizes detection of small targets and reduced noise

• We back up our reliability with a TWO YEAR

Overview:

Very high resolution Cesium Vapor performance is now available in a low cost, small size system for professional surveys in shallow or deep water. High sensitivity and sample rates are maintained for all applications. The well proven Cesium sensor is combined with a unique new CM-221 Larmor counter and ruggedly packaged for small or large boat operation. Use your computer and standard printer with our MagLog Lite™ software to log, display and print GPS position and magnetic field data. The  G–882 is the lowest priced high performance full range marine magnetometer system ever offered.

Configurations:

he G-882 is flexible for operation in small boat, shallow water surveys as well as deep tow applications (4,000 psi rating, telemetry over steel coax available to 10Km). Being small and lightweight (40 lbs net, no extra weights) it is easily deployed and operated by one person.   But add several streamlined weight collars and the system can quickly weigh more than 100 lbs. Power may be supplied from a 24 to 30 VDC battery power or the included 110/220 VAC power supply. The tow cable employes high strength Kevlar with a standard length of 200 ft (61 m) and optional cable length up to 500m (no telemetry required). A rugged fiber-wound fiberglass housing provides selectable orientation of the sensor and therefore maintains operations throughout the world with only small limitations as to direction of survey in equatorial regions. The shipboard end of the tow cable is attached to an included  junction box or optional on-board cable for quick and simple hookup to power and output of data into any Windows 98, ME, NT, 2000 or XP computer equipped with RS-232 serial ports.

The G-882 Cesium magnetometer provides the same  operating sensitivity and sample rates as the larger deep tow model G-880. MagLogLite™ Logging Software is offered with each magnetometer and allows recording and display of data and position with Automatic Anomaly Detection!   Additional options include: MagMap2000 plotting and contouring software and post acquisition processing software MagPick™ (free from our website.)
 

The G-882 system is particularly well suited for the detection and mapping of all sizes of ferrous objects. This includes anchors, chains, cables, pipelines, ballast stone and other scattered shipwreck debris, munitions of all sizes (UXO), aircraft, engines and any other object with magnetic expression. Objects as small as a 5 inch screwdriver are readily detected provided that the sensor is close to the seafloor and within practical detection range.

The design of this high sensitivity G-882 marine unit is directed toward the largest number of user needs. It is  intended to meet all marine requirements such as shalllow survey, deep tow through long cables, integration with Side Scan Sonar systems and  monitoring of fish depth and altitude.
