The EdgeTech 4125i uses EdgeTech's Full Spectrum CHIRP technology and operates two frequencies simultaneously from a stainless steel towfish.\n\nTwo frequency sets are available for the EdgeTech 4125i. The 400\u002F900 kHz towfish has an operating range of 150 m at 400 kHz and 75 m at 900 kHz, with across-track resolution of 2.3 cm at 400 kHz and 1.0 cm at 900 kHz. The 600\u002F1600 kHz towfish has an operating range of 120 m at 600 kHz and 35 m at 1600 kHz, with across-track resolution of 1.5 cm at 600 kHz and 0.6 cm at 1600 kHz. Horizontal beam width is 0.46° at 400 kHz, 0.28° at 900 kHz, 0.33° at 600 kHz and 0.20° at 1600 kHz, and vertical beam width is 50°.\n\nThe EdgeTech 4125i towfish is 9.5 cm in diameter and 112 cm long, weighs 20 kg in air and has a max depth rating of 200 m. Heading, pitch, roll and pressure (depth) sensors are standard. The towfish can be used with a coaxial tow cable of up to 600 m max length, which gives a typical operational depth down to 200 m, and the system includes a safety recovery system intended to prevent loss of the towfish if it becomes snagged on an obstacle.\n\nA standard EdgeTech 4125i system comes with the towfish, a portable water-resistant topside processor including a laptop computer and a 50 m Kevlar tow cable, delivered in portable rugged cases. The topside processor runs on 12–24 VDC or 115\u002F230 VAC, 50\u002F60 Hz, connects to the laptop over Ethernet and uses EdgeTech DISCOVER acquisition software on Windows 7 and Windows 10. Options include a splash-proof\u002Fruggedised laptop, keel weight, v-fin depressor wing, pole mount and quick change hull scan bracket. Listed applications are hydrographic surveys, geological surveys, search and recovery, channel\u002Fclearance surveys, bridge\u002Fpier\u002Fharbour wall inspection and hull inspections.",false,[41,42,43,44,45,46],"Choice of 400\u002F900 kHz or 600\u002F1600 kHz towfish","Range 150 m @ 400 kHz, 35 m @ 1600 kHz","Across-track resolution 0.6 cm @ 1600 kHz","Towfish depth rating 200 m","Towfish 20 kg in air, 9.5 cm Ø × 112 cm","Runs on 12–24 VDC or 115\u002F230 VAC","EdgeTech",{"_type":49,"asset":50},"image",{"_ref":51,"_type":34},"image-c4d70150cff245ade6eddca1c550a0406d1cb3e8-904x406-png","Rent an EdgeTech 4125i dual frequency side scan sonar with a 400\u002F900 kHz or 600\u002F1600 kHz CHIRP towfish, up to 150 m range and a 200 m depth rating.","EdgeTech 4125i Side Scan Sonar, 200 m","EdgeTech 4125i dual frequency side scan sonar with a 400\u002F900 kHz or 600\u002F1600 kHz towfish, Full Spectrum CHIRP, up to 150 m range and a 200 m towfish depth rating.",{"_type":56,"current":57},"slug","edgetech-4125i-dual-frequency-side-scan-sonar","Dual Frequency Side Scan Sonar",[60,65,69,73,77,81,85,89,93,97,101,105,109,113,117,121,125,129,133,137,141,145,149],{"_key":61,"_type":62,"label":63,"value":64},"c23583f5e36d","specRow","Frequencies (dual simultaneous)","Choice of either a 400\u002F900 kHz or 600\u002F1600 kHz towfish",{"_key":66,"_type":62,"label":67,"value":68},"221f979a5733","Pulse type","EdgeTech Full Spectrum CHIRP",{"_key":70,"_type":62,"label":71,"value":72},"9502cf7f1a2e","Operating range","150 m @ 400 kHz;
