It’s Small, But Purposefully So

The S1 Pro is designed with portability in mind. Weighing just 2.5 kg and measuring under 12 inches in length, it’s one of the most compact underwater scooters available. This makes it easy to transport, store, and use—even when traveling by air, thanks to its airline-compliant 97.68 Wh battery.

That size does come with trade-offs. It’s not built for maximum thrust or extended endurance. If you’re after high power or long-range dives, this might not be your tool of choice. But for short to moderate excursions, it’s more than capable.

Modularity Sets It Apart

A defining feature of the S1 Pro is its modular design. The scooter can be handheld or mounted to a scuba tank, paddleboard, or even your legs—depending on how you want to use it. With the right accessories, it can transition between solo use and dual-scooter setups for added thrust and control.

The modularity does require some investment. Accessories such as mounting kits, rail systems, and dual-unit kits add to the total cost.

This is worth considering if you're looking to unlock its full range of configurations.

Performance Is Balanced, Not Extreme

In terms of power, the S1 Pro delivers up to 8 kgf of thrust and reaches a top speed of approximately 1.8 m/s on a single unit—or up to 2.3 m/s when using a dual configuration. That’s plenty for casual diving, snorkeling, and surface propulsion, but it’s not built for fast currents or commercial use.

Battery life ranges from 35 to 70 minutes, depending on the power setting and usage. Swapping batteries is quick, and extra units are available, but runtime remains a limitation for longer dives.

‎

Price is Mid-Range Choice, and It Shows

Priced at around $699 USD, the S1 Pro falls into a competitive mid-range bracket. It’s not as powerful or silent as premium models like the LEFEET P1, but it offers a balanced mix of portability, build quality, and customization potential.

The frame is built from durable aluminum alloy with a carbon-fiber propeller, giving it resilience in saltwater conditions. Noise levels are noticeable but acceptable for recreational use.

‎

Who It’s For

The S1 Pro is a solid fit for:

Casual divers or snorkelers looking for added range without bulk
Frequent travelers needing airline-compliant gear
Users who value modular, adaptable gear for multiple water activities

It may not be ideal for:

Technical or professional divers requiring extended thrust or depth
Those seeking out-of-the-box maximum performance

Final Thoughts

The LEFEET S1 Pro doesn’t overpromise—and that’s part of its appeal.

It’s a compact, well-made underwater scooter for those who need a reliable, flexible propulsion tool without stepping into ultra-premium territory. If your underwater excursions prioritize ease, mobility, and modularity, it deserves serious consideration.
