Small, stable and ready in minutes
The M2 S is the easy-to-carry member of the CHASING M2 family - a compact underwater drone that one person can launch from a dock, boat or bank and have eyes on a subject in minutes. Eight vectored thrusters with anti-stuck C-Motor 3.0 keep it steady and responsive on every axis, while depth, heading and attitude lock hold a clean shot hands-free.

Why the M2 S is the one you reach for
A first look underwater shouldn't be a production. The M2 S makes quick checks genuinely quick.
01Truly Portable
Light enough to carry to the water's edge and launch solo - no crane, no crew.
02Stable Control
Eight vectored thrusters keep the vehicle steady and easy to fly on every axis.
03Hands-Free Hold
Depth, heading and attitude lock hold position so you can focus on the footage.
04Clean 4K
4K UHD with EIS produces smooth, sharp records even in moving water.
Eight Vectored Thrusters · True 360° Control
A symmetrical eight-thruster vectored layout, driven by Apex anti-stuck C-Motor 3.0, delivers stable, responsive movement on every axis - and full 360° omnidirectional manoeuvring.
Steady where it counts
Eight symmetrically arranged vectored thrusters give the M2 S true 360° omnidirectional control - drive forward, strafe, climb, descend, pitch and turn with fine, predictable response. Apex anti-stuck C-Motor 3.0 resists fouling from weeds and debris, while the lock modes keep the vehicle parked on target without constant stick input.
- Eight thrusters for 360° omnidirectional movement
- Apex anti-stuck C-Motor 3.0 - debris-resistant drive
- Depth, heading and attitude lock for hands-free hover
4K UHD · Electronically Stabilised
A 4K Sony-sensor camera with EIS and twin 2,000 lm LEDs (4,000 lm total) captures clean, usable footage for inspection and documentation - streamed live to your device.
Sharp, steady footage you can rely on
A Sony CMOS sensor with an F2.8 aperture and ~150° wide field of view records 4K UHD video with electronic image stabilisation, so footage stays smooth as the vehicle moves through the water. CHASING's Aquavision image algorithm restores natural colour underwater, twin 2,000 lm LEDs (4,000 lm total) open up low-visibility scenes, and the live feed streams to your device for instant review.
- 4K UHD video · 12 MP stills · Sony CMOS · F2.8 · ~150° FOV
- Electronic Image Stabilisation (EIS) + Aquavision colour algorithm
- Twin 2,000 lm LEDs (4,000 lm total) · three brightness levels
- Live view and capture to your phone or tablet

4K UHD Capture
Sony CMOS sensor, F2.8 aperture and ~150° FOV record sharp 4K video and 12 MP stills.
EIS + Aquavision
Electronic stabilisation plus CHASING's Aquavision algorithm - smooth video with true underwater colour.
4,000 lm Lighting
Twin 2,000 lm LEDs deliver 4,000 lm combined, with three brightness levels to light up murky or deep scenes.
Live View & Capture
Stream the live feed to your phone or tablet and review captures on the spot.
Lock Modes
Depth, heading and attitude lock keep the camera steady on the subject hands-free.
Accessory-Ready
Compatible with CHASING add-ons to extend the M2 S for specific tasks.
The M2 S at Work
Compact enough for anywhere there's water - quick to deploy for a first look, a routine check or a recorded survey.
Adapt it to the task
The M2 S works with a range of CHASING add-ons so you can tailor it to the job - from grabbers for light retrieval to extra lighting and mounting options. Tell us what you need to do underwater and we'll specify the right accessory set.
- Intervention: Grabber Claw A, Grabber Arm 2, circular and salvage circular claws
- Sampling & search: sediment sampler, underwater metal detector
- Measurement: laser scaler for contact-free sizing, distance-lock sonar
- Lighting: Floodlight 2 or the higher-output underwater LED video light
- Tether handling: manual reel, E-Reel, or reels pre-spooled to 300 m / 400 m
- Endurance: 200 Wh spare battery and a 50 W car/boat charger for field turnarounds
- Control: Remote Controller 3, or the WSRC waterproof screen controller for open decks
Choose Your Set
CHASING builds the M2 S in three sets. The difference is not the vehicle - it is how much tether handling, lighting and intervention capability comes in the box.
Lite
The vehicle and a 100 m tether with no reel, paid out and recovered by hand. Shallow, close-in work from a bank or small boat.
- CHASING M2 S ROV
- Remote controller
- 100 m tether (no reel)
Standard Set
Adds the reel, double the tether, spare motors and a second light - the practical daily-use build.
- CHASING M2 S ROV
- Remote controller
- Reel with 200 m tether
- 2 × spare motors
- Floodlight 2
Advanced Set
Everything in the Standard Set, plus intervention, transport and a longer working day:
- Grabber Claw A
- 200 Wh battery
- Carrying case
Buying the Lite set and adding the reel and Floodlight 2 later already costs more than starting at Standard, before the 200 m tether and spare motors. Tell us the depth, the current and how far offshore and we will say which set is actually the cheapest way to do the job.
