Gladius Mini S Underwater Drone

Exploring the underwater world becomes much easier and more professional with this advanced ROV. Designed with a compact body and powerful performance, it is built to go deep, capture high-quality visuals, and deliver stable operation in challenging conditions. Whether you are into underwater photography, inspections, or marine research, this ROV provides a perfect blend of durability, technology, and convenience, making it a reliable companion for every dive.

1. Compact and Lightweight Design

With a size of 400 × 226 × 145 mm and a weight of just 2.7 kg, this ROV is designed for portability without compromising on durability. Its compact frame makes it easy to transport, deploy, and operate, while still being tough enough to handle underwater tasks at significant depths. This balance of size and strength ensures convenience for both professional and recreational users.

The ROV is powered by dual 4800 mAh batteries, providing a reliable runtime of up to 4 hours depending on usage conditions. This extended operation time allows users to conduct longer inspections, surveys, or filming sessions without frequent interruptions. The dependable battery capacity ensures you can focus more on your underwater mission and less on recharging.

Equipped with a 1/2.3 CMOS sensor and F2.8 lens, the camera delivers sharp 12MP photos and vibrant underwater videos. The wide 150° field of view ensures expansive coverage, while the focus range from 0.3 m to infinity captures details at every distance. It supports photo formats like JPEG and DNG, giving flexibility for professional editing and creative workflows.

This ROV is not just about photos — it excels in video recording too. It supports 4K video at 25/30fps and 1080P at frame rates up to 120fps for smooth playback. For creative projects, users can take advantage of 4X and 8X slow-motion recording, as well as 4K and 1080P time-lapse. With a 60M video stream and MP4 format support, the ROV is built to meet the needs of professionals who demand both quality and versatility.

Underwater visibility is enhanced with two powerful 1200-lumen LED lights, combining for a total brightness of 2400 lumens. Operating at a color temperature of 5000K – 5500K, these lights simulate natural daylight, delivering true-to-life colors. With a CRI of 85, they enhance color accuracy, and the three-step brightness adjustment ensures flexibility in different underwater conditions, from shallow dives to darker depths.

The ROV comes equipped with advanced sensors that ensure accurate data and stable operation. Its three-axis gyroscope, accelerometer, and compass provide smooth navigation and orientation control. The depth sensor delivers precision within ±0.25 m, while the temperature sensor is accurate within ±2 °C. These technologies guarantee dependable performance in varying underwater environments.

To maintain secure communication and control, the ROV is connected via a durable tether cable. The standard 100 m cable weighs 1.8 kg, while an optional 200 m cable is available for extended range operations. Designed to withstand underwater challenges, the tether ensures uninterrupted signal and data transfer, making it suitable for both shallow and deep-water tasks.

The remote controller measures 160 × 155 × 125 mm and weighs 685 g, offering a lightweight yet sturdy design. With a built-in 2500 mAh battery, it provides up to 26 hours of runtime, allowing extended use without frequent recharging. It supports Wi-Fi connectivity, HDMI output, and multiple wired ports including Lightning, Micro USB, and USB-C. The handle spring can hold devices up to 10 inches, providing flexibility and convenience for real-time viewing.

Keeping downtime minimal, the ROV features a powerful 3A / 12.6V charger. It takes around 3.5 hours to fully charge the ROV and just 2 hours to recharge the remote controller. This fast and efficient charging ensures that both the ROV and controller are ready for extended underwater operations with minimal waiting time.

Built to withstand demanding conditions, the ROV operates efficiently within a temperature range of -10°C to 45°C. This ensures reliability whether used in colder freshwater environments or warmer coastal waters. Combined with its ability to dive up to 100 meters, it is designed for versatile use across a wide variety of underwater applications.
