The EdgeTech 3400-OTS uses a flat multi-channel hydrophone array to image sub-bottom stratigraphy in oceans, lakes and rivers. The receiver array is segmented for standard sub-bottom profiling or a pipeline mode for locating and imaging buried pipelines or cables.\n\nThe EdgeTech 3400-OTS is available in a 4–24 kHz and a 2–16 kHz version. The 3400-OTS Ultra-Light operates at 4–24 kHz with one transmitter and 4–8 cm vertical resolution, gives typical penetration of 2 m in sand and 40 m in clay, measures 77 × 33 × 34 cm and weighs 21.4 kg in air. The 3400-OTS Light operates at 2–16 kHz with one transmitter and 6–10 cm vertical resolution, gives typical penetration of 6 m in sand and 80 m in clay, measures 77 × 33 × 34 cm and weighs 26.3 kg in air. Both versions use a 200 W power amplifier and a 20 m deck cable (50 m max).\n\nThe EdgeTech 3400-OTS provides real-time reflection coefficient measurements for measuring sediment reflection and determining sediment type, and its discrete transmit and receive channels allow continuous data collection. Other listed features are a digital receiver with Ethernet telemetry and power, real-time pitch, roll, heave and depth sensors, surface echo attenuation and a pulse library for different survey applications. The topside interface is a rugged, portable splash-proof enclosure (or rackmounted) with 120\u002F220 VAC auto-sensing power input, Ethernet input\u002Foutput, native JSF, SEG-Y and XTF file formats and Windows 10 as the recommended operating system; a splash-resistant semi-rugged laptop display is optional.\n\nThe EdgeTech 3400-OTS comes as a complete package with EdgeTech DISCOVER sub-bottom acquisition and processing software and can also be interfaced to third-party software. Listed applications include geological surveys, environmental site investigations, sediment classification, buried pipeline and cable surveys, archaeological surveys, mining\u002Fdredging surveys and mapping, measuring and classifying sediment layers within the seafloor.",[239,240,241,242,243,244],"Ultra-Light: 4–24 kHz, 4–8 cm vertical resolution","Light: 2–16 kHz, 6–10 cm vertical resolution","Typical penetration in clay: 40 m (4–24 kHz), 80 m (2–16 kHz)","Weight in air 21.4 kg (4–24 kHz), 26.3 kg (2–16 kHz)","Pipeline mode; pitch, roll, heave and depth sensors","20 m deck cable (50 m max)","EdgeTech",{"_type":247,"asset":248},"image",{"_ref":249,"_type":233},"image-92a05104339d43a8beab3bd89add5f46455f5209-887x450-png","Rent an EdgeTech 3400-OTS over-the-side sub-bottom profiler with CHIRP, in 4–24 kHz or 2–16 kHz versions with up to 80 m typical penetration in clay.","EdgeTech 3400-OTS Sub-Bottom Profiler","EdgeTech 3400-OTS over-the-side pole mount sub-bottom profiler with Full Spectrum CHIRP, available as a 4–24 kHz Ultra-Light or 2–16 kHz Light version with up to 80 m typical penetration in clay.",{"_type":254,"current":255},"slug","edgetech-3400-ots-sub-bottom-profiler","Over-the-Side Pole Mount Sub-Bottom Profiler",[258,263,267,271,275,279,283,287,291,295,299,303,307,311,315,319,323,327,331,335,339,343,347,350],{"_key":259,"_type":260,"label":261,"value":262},"c12f99038bf5","specRow","System type","Over-the-side pole mount sub-bottom profiler",{"_key":264,"_type":260,"label":265,"value":266},"e44bc1c143e5","Versions covered","3400-OTS Ultra-Light (4–24 kHz); 3400-OTS Light (2–16 kHz)",{"_key":268,"_type":260,"label":269,"value":270},"b2d8a37e7a55","Frequency range","4–24 kHz (Ultra-Light); 2–16 kHz (Light)",{"_key":272,"_type":260,"label":273,"value":274},"8484d575b712","Number of transmitters","1 (Ultra-Light); 1 (Light)",{"_key":276,"_type":260,"label":277,"value":278},"a18a356297d2","Vertical resolution","4–8 cm (Ultra-Light); 6–10 cm (Light)",{"_key":280,"_type":260,"label":281,"value":282},"edda3e8a6801","Penetration in sand (typical)","2 m (Ultra-Light); 6 m (Light)",{"_key":284,"_type":260,"label":285,"value":286},"f9b1953dc18d","Penetration in clay (typical)","40 m (Ultra-Light); 80 m (Light)",{"_key":288,"_type":260,"label":289,"value":290},"d5fea0bf8dca","Transmission type","Full Spectrum FM signal (CHIRP)",{"_key":292,"_type":260,"label":293,"value":294},"3d53287171e3","Dimensions (L × W × H)","77 × 33 × 34 cm (Ultra-Light); 77 × 33 × 34 cm (Light)",{"_key":296,"_type":260,"label":297,"value":298},"829a84e93c14","Weight in air","21.4 kg (Ultra-Light); 26.3 kg (Light)",{"_key":300,"_type":260,"label":301,"value":302},"21c9217dd06f","Deck cable length","20 m (50 m max)",{"_key":304,"_type":260,"label":305,"value":306},"2b4689612af6","Power amplifier","200 W (Ultra-Light); 200 W (Light)",{"_key":308,"_type":260,"label":309,"value":310},"c5615e3dc9c0","Receive array","Flat multi-channel hydrophone array, segmented for standard or pipeline mode",{"_key":312,"_type":260,"label":313,"value":314},"aa4dacd9bcc6","Receiver","Digital receiver with Ethernet telemetry and power",{"_key":316,"_type":260,"label":317,"value":318},"e273080cd92b","Sensors","Real-time pitch, roll, heave and depth",{"_key":320,"_type":260,"label":321,"value":322},"75f40093a16c","Other features","Real-time reflection coefficient measurement; surface echo attenuation; pulse library for different survey applications; discrete transmit and receive channels",{"_key":324,"_type":260,"label":325,"value":326},"3f1d58f92a58","Topside hardware","Rugged, portable splash-proof enclosure (or rackmounted)",{"_key":328,"_type":260,"label":329,"value":330},"d78275cb51b0","Recommended operating system","Windows 10",{"_key":332,"_type":260,"label":333,"value":334},"f401744ee244","Display","Splash-resistant semi-rugged laptop (optional)",{"_key":336,"_type":260,"label":337,"value":338},"a23bf0f67318","File format","Native JSF, SEG-Y & XTF",{"_key":340,"_type":260,"label":341,"value":342},"6ace6f8ed21d","Input\u002Foutput","Ethernet",{"_key":344,"_type":260,"label":345,"value":346},"371325d491f4","Power input","120\u002F220 VAC auto sensing",{"_key":348,"_type":260,"label":67,"value":349},"b5faa74d15af","EdgeTech DISCOVER sub-bottom acquisition & processing; can be interfaced to third-party software",{"_key":351,"_type":260,"label":352,"value":353},"02162c3d2ea8","Applications","Geological surveys, environmental site investigations, sediment classification, buried pipeline & cable surveys, archaeological surveys, mining\u002Fdredging surveys, mapping and classifying sediment layers"]
