一、USA 探地成像仪简介
　USA探地成像仪是一种利用探测地球电磁场遇到不同介质而产生的变化来实现三维图象的探地测量仪器。它不需要发射信号到地球，而是利用地球内部已经存在的地球电磁场信号，防止了普通探地雷达的大功率发射信号对人体和环境的影响，同时也不受外部环境的干扰，适用于各种复杂的环境。
　　 USA探地成像仪使用方便，成像清晰，层次分明，立体感强，判断准确，是现在市场可以同时实现金属物体和非金属物体探测的地下成像探测仪。
　　 USA探地成像仪由于其优良的性能价格比，广泛应用与地下金属管线和非金属管线的探测、废旧物和污水池搜寻、道路施工验收、军用未爆破物搜寻、楼房基础探测、水下各种物体和大坝管涌的搜寻和考古研究。除了在平坦的场所应用，而且可以用于山道、水面等区域。
USA探地成像仪的探测速度是其他探测仪无法比拟的，他可以与汽车和快船一起使用。探测质量和数据分析能力也是其他种类的成像探测仪所不及的。

【特点】

USA探地成像仪是现代唯一能同时发现所有金属和非金属物体的探地仪器，其最大探测深度可达30米。它可以通过手持、便携、手推车、车载、船只对各种环境进行地下成像探测，主要应用有：
◆环境监测：探测各种用于偷排放污水的各种地下金属管线和非金属管线，隧道、污水池。
◆市政建设：探测出各种金属和非金属管道和管线，以防止道路施工造成管道的破坏。
◆石油行业的物探：可以同时探测金属管道和PVP管道。
◆矿产探测：各种地下矿藏、堆积砂矿的探测。
◆大坝管涌的探测：大坝管涌是由于大坝内部被掏空而形成，可以采用手持和车载等方式在大坝上快速进行探测，可以很及时地发现将要发生大坝管涌的位置。
◆水下探测：水面下金属和非金属物体、管线走向，矿藏，沉船，污水池和故障点的探测。
◆考古探索：古墓和宝藏与周围环境有明显的不同，可以用用USA探地成像仪对可疑地点进行探测。
◆房屋地基的探测：进行房屋建设前的地基探测，探测出地基下存在的洞穴。
◆军事应用：对演习地和相关地点进行未爆炸物的探测，由于没有发射，不与地面接触，所以十分安全。

See what Gold Prospectors Magazine had to say about our Underground Surveyor Apparatus(USA) products in their Jan/Feb 2006 magazine. Read about 'Testing Accurate Locators A Field Test' by Jim Klein and his use of the USA product line in his search for gold here.Pinpointer Technology Update
 Pinpointer 2.0 ART has been released!
Our new Pinpointer system for all of the USA Systems now has ART Audio Response Targeting for heads up detection making rapid pinpointing of target and depth estimation even easier. Great for pinpointing tunnels, metals, voids, gold veins, lost treasure, utilities and other underground anomalies. Now Available with Runabout and Double Magnum. Read more about the pinpointer here.

'The Challenge of the Hunt'
 The Underground Surveyor Apparatus (USA) Multi-Sensor units are a state of the art Multi-Sensor Array that are capable of extraordinary sampling rates producing detailed yet the most efficient results up to 200 feet! The USA are well suited for both the utility locator as well as the Professional Treasure Hunter. The USA has advanced software which makes operating the units much simpler than other brands available, and the software is included with the purchase at no extra charge.'The Thrill of the Finds'
The Magnum has a double sensor antenna which is designed for the purpose of locating larger items including buried treasures, caves, tunnels and voids. See subsurface objects in real-time with the GeoSurveyor 3-D software and the Runabout, Discovery and Imager units. The Magnum receives a high sampling rate in favorable ground conditions and can detect larger objects and tunnels at 120 feet. The USA comes complete with a pre-configured laptop computer, control unit, sensor housing, extension shaft, battery, charger, all connection cables, custom dual field pack with Camelbak personal water reservoir, carrying case, video, user manual, 2-hour tech support or training by appointment (on-site) and a 1-year limited warranty. The Magnum is the choice of many hobbyists and treasure hunter.'GeoSurveyor' Software
 The GeoSurveyor software was developed exclusively for the USA. The software was built with simplicity of use in mind. The software has functions to show a standard 2-D top view and 3-D at the same time which includes the side scan information. Advanced filtering techniques also enhance the images to better identify targets. The USA Ground Imaging Systems are fully controlled by the GeoSurveyor software developed for the operator to perform scans quickly and easily.The software renders a 3-D image and has user-definable and factory presets to enable quick analysis and target identification. One of the most distinguishing features of the USA Runabout, Discovery and the Imager  is the 'Real-Time Live Mode'. The live mode enables the user to scan in any direction to locate subsurface anomalies. The uniqueness is the speeds that they are capable of traveling, you can run if you like, with astonishing results and full screen viewing.The USA technology has been successfully deployed in various climatic and geological conditions by both professionals and amateurs. Applications include archaeology, geophysics, geology, hydrology and treasure hunting. Surveyed areas include industrial waste sites and waste deposits, building lots, mining areas, street construction sites, military practice sites and other sub-surface investigations.The USA Field Pack was custom-made for the serious professional. Not only  does it come with enough room for your gear, but also for the laptop and control unit plus batteries. The packs are evenly balanced to create comfort with very little body strain. The USA Field Pack comes in an assortment of colors, as well as two sizes depending on the size of the laptop, large or small.The GeoCaddy is available as an accessory for the Discovery, Imager and Runabout to help maintain even scans while the caddy  holds all the gear and extra batteries for longer life in the field.Antenna Case with shoulder strap can accommodate up to 3 antennas for added protection. Available standard with Discovery and Imager packages. Optional for other models.
