Description
The DF-6908 8-inch Digital Echo Sounder is a robust and versatile sonar depth-sounder engineered for inland-water vessels and shallow-water navigation.
DF-6908 is an independent dual-channel (200KHz / 200KHz) digital echo sounder. It is suitable for inland navigation vessels. It supports 0.2m depth water measurement and features functions such as shallow water alarm and depth water alarm.
◆ High-contrast 8-inch color LCD display, 1024 x 600 high resolution.
◆ Adopt high-precision digital signal processing technology(DSP).
◆ Detect 0.2m ultra-low water level.
◆ Built in large capacity memory, with the function of storing and replaying water depth data; The echo data can be adjusted during playback (range, gain, color can be adjusted).
◆ Multiple protection: over voltage protection, over current protection, reverse connection protection.
◆ Built in WiFi module.
◆ Automatic function permits unattended adjustment of range. The range scale automatically change to display the bottom.
