Edgetech 4125 / 4125i: Ultra High Resolution Lightweight, Portable

The Industry Standard for Rapid-Response Search & Recovery and Shallow Water Surveys

Product Overview 

The EdgeTech 4125i is a high-definition, dual-simultaneous side scan sonar system designed for the Search & Recovery (SAR) and shallow water survey communities. It utilizes EdgeTech’s proprietary Full Spectrum® CHIRP technology to deliver images with up to 50% greater range and higher resolution than non-CHIRP systems at the same frequency.

The "i" variant is the current generation, featuring upgraded digital telemetry (replacing legacy xDSL modems) for more robust data transfer and compatibility with modern topside processors. Engineered for "one-person" deployment, the system can be mobilized from small boats of opportunity in minutes, making it the premier choice for law enforcement, harbor security, and hydrographic professionals.

Why Choose the EdgeTech 4125i?

• Ultra-High Resolution Imagery: Provides the crispness required to detect and identify very small targets, such as anchors, cables, or forensic evidence, even in turbid water.
• Portable & Ruggedized: The entire system—including the towfish, 50m cable, and topside processor—is delivered in a series of rugged transit cases, allowing for easy transport by commercial airline or small vehicle.
• Integrated Sensor Suite: Features built-in sensors for Heading, Pitch, Roll, and Pressure (Depth) as standard, ensuring all imagery is accurately georeferenced and corrected for vessel motion.
• Dual Simultaneous Frequencies: Operates two frequencies at once, allowing for a wide search swath and high-resolution target identification in a single pass.
• Versatile Power Options: Can be powered by 12-24 VDC (battery) or 115/230 VAC, making it ideal for open boat operations where a generator may not be available.
