The SXCSSN16 is a handheld underwater sonar detection and diver positioning system. Equipped with dual-frequency imaging sonar and a 7-inch color display, it supports underwater search, inspection, navigation, and recovery missions in low-visibility environments.
Key Features
01. Dual-Frequency Imaging Sonar
Uses an M750D imaging sonar with dual-frequency operation at 750 kHz and 1.2 MHz. The lower frequency provides a wider field of view and longer detection range, while the higher frequency delivers detailed short-range imaging. Supports image zoom, rotation, and view-angle switching.
02. 7-Inch Color Display
A 7-inch color screen presents sonar images, navigation information, and system status. Eight physical buttons allow divers to switch between sonar, navigation, and other function screens underwater, with adjustable brightness for varying light conditions.
03. Integrated Navigation Sensors
Built-in pressure, temperature, compass, and battery sensors provide real-time depth, water temperature, attitude, and power status during operation. Sonar data can be recorded, stored, and replayed for later review.
04. Underwater Positioning
Compatible with external underwater positioning equipment, supporting acoustic positioning up to 1,000 meters with stated accuracy of ±0.1 meter and tracking up to 14 beacons. Wired and wireless options allow data transfer to a surface terminal.
05. Portable and Field-Ready
Constructed with buoyant materials for near-neutral buoyancy in water. A replaceable battery compartment supports at least 6 hours of operation, with charging time up to 4 hours. Suitable for underwater inspection, search and rescue, diver navigation, marine research, and archaeology.
