TD-MS400P Multibeam Echo Sounder

Introduction
TD-MS400P is an ultra-miniature and ultra-low-power all-in-one multibeam echo sounder, specially developed for portable and mobile underwater survey applications. It is easy to install and operate, suitable for all kinds of rubber boats, rafts, etc. Its installation can be completed by only one person, and it can be installed anytime as needed, and can be used immediately after installed, as simple as a single beam.

Features
●High performance: Beam angle 1°×2°, number of beams 512, depth resolution 0.75cm, and the measurement results meet IHO super-level standard.
●Low power consumption: The power consumption is as low as 60W, and it can work continuously for more than 8h with a common electric vehicle lithium battery.
●Small size: The size is 288mm×240mm×120mm (length × width × height), a A4 printing paper size, and it can be put into a backpack for carriage.
●Light weight: The whole device weight is 8.3kg and can be easily picked up, quick to install and easy to carry.
