World's Most Compact Design
Extremely compact size, weighing only 0.37-0.76kg, easy to integrate into various underwater platforms.

The Impact Subsea ISS360 Series is the world's most compact line of high-performance imaging sonars, comprising two models: the ISS360 (Standard) and the ISS360HD (High-Resolution). This series is renowned for its extremely small size, deep-water capability, and exceptional image quality, fundamentally changing underwater detection and navigation methods.
The ISS360 series utilizes a wideband composite transducer combined with advanced IS³ signal processing technology. Through advanced phase modulation and coding techniques, it delivers excellent signal integrity, timing accuracy, and range resolution. The products are available with depth ratings of 4000 meters and 6000 meters, and optionally integrate a high-precision pitch & roll sensor for attitude-compensated imaging. Its slip-ring-free design ensures reliability with no moving parts. The ISS360HD model further enhances horizontal resolution and maximum range compared to the standard version, making it an ideal choice for applications demanding the utmost image detail.

Extremely compact size, weighing only 0.37-0.76kg, easy to integrate into various underwater platforms.
Supports 360° continuous scanning or adjustable sector scanning, providing complete underwater situational awareness.
ISS360 balances coverage and detail, while ISS360HD offers extreme resolution and longer detection range.
Available in 4000-meter and 6000-meter depth ratings, suitable for various operating environments from shallow water to deep sea.
Integrated pitch and roll measurement with ±0.2° accuracy for attitude-compensated imaging.
