MANTA 2 Sea Scooter Guide: Safety, Speed, and Care

If you’re new to underwater scooters, the MANTA 2 is designed to make snorkeling and recreational diving feel easier, smoother, and more fun without a steep learning curve. 

This guide walks you through what the MANTA 2 is, how its speed modes work in real life, how to start and stop safely, and how to care for it after each session so it stays reliable for the long run.

What the MANTA 2

The MANTA 2 is a compact sea scooter built for underwater propulsion in activities like snorkeling, freediving, and recreational scuba. It’s sized to be easy to carry and handle while still delivering strong thrust and multiple speed options for different comfort levels and conditions.

It’s recommended for users age 14 and up, and it’s best for swimmers who are comfortable in open water and understand basic water safety. If you’re not a confident swimmer, use it only with proper supervision and flotation support.

Key Specs

Specs are helpful, but what matters most is how they translate to actual use.

Speed and Modes: What “3 Levels” Really Means

The MANTA 2 has three speed levels, which lets you choose a slower, more relaxed pace or a faster pace for short bursts.

• Level 1: Built for comfort and longer exploration.

• Level 2: A balanced everyday mode for covering more distance.

• Level 3: Maximum speed for short, high-power runs.

In the user manual, the speed and runtime ranges are listed as:

• Level 1: 0.6 m/s, up to 90 minutes

• Level 2: 2.0 m/s, up to 30 minutes

• Level 3: 2.5 m/s, up to 13 minutes

That big swing is normal: higher speed requires more power, so you’ll get less time at the top setting.

Depth Rating: What It Means

The MANTA 2 is rated up to 40 m / 130 ft. That’s the maximum depth rating, not a recommendation for every user. For most recreational use snorkeling and casual dives you’ll be operating much shallower.

Weight and Handling

At 4.5 kg / 9.9 lb, it’s manageable for carrying to the water and for controlling underwater. That balance of portability and thrust is a big part of what makes it friendly for newer users.

The Quick Safety Setup

A few minutes of preparation can prevent most problems.

Use the Right Safety Gear

For snorkeling or surface use, wearing a PFD (personal flotation device) is strongly recommended. It helps reduce fatigue and improves safety if conditions change.

Choose a Safe Area

Avoid areas with boat traffic, crowded swim zones, or obstacles. Underwater scooters can cover distance quickly, so it’s easy to drift farther than you expect if you’re not paying attention.

Keep Fingers and Objects Away From the Propeller Guard

Never put fingers, hair, straps, or debris near the propeller area. Even with a protective design, it’s not a place you want anything to get pulled into.

Keep Electrical Connectors Dry

The manual emphasizes keeping battery connectors dry. Water in connectors can lead to corrosion, poor contact, or electrical issues over time. If you’re swapping batteries or handling charging gear, do it in a clean, dry place.

Installing the Battery

Battery handling is one of the biggest “make it last” habits.

1. Insert the battery into the unit until it seats properly.

2. Secure the internal latch so it locks in place.

3. Confirm the battery is fully positioned and stable.

Important rule: Do not replace the battery underwater, and don’t place the battery pack in water. The manual also warns to keep the connector dry during changes, especially after saltwater use.

Start and Stop

The MANTA 2 uses a simple two-trigger control system designed to reduce accidental activation.

Starting

1. Place the scooter in the water.

2. Unlock the switch lock (this is your safety lock).

3. Press and hold both triggers to start propulsion.

Stopping

• Release either trigger to stop.

• When you’re out of the water, lock the switch lock again.

This “two-trigger” approach is a good habit for safety and control—especially if you’re handing the scooter to someone else or adjusting your mask.

How to Change Speed Levels

Speed changes are done with a combination of trigger hold + double press.

To Increase Speed

• Hold the left trigger, then double-press the right trigger.

To Decrease Speed

• Hold the right trigger, then double-press the left trigger.

A practical tip: always start in Level 1 your first few minutes in the water. It gives you time to settle your breathing, adjust your buoyancy, and get a feel for steering before you speed up.

Getting the Best Performance Underwater

Use Level 1 to Learn Control

Most “this feels hard to steer” feedback comes from going too fast too soon. Level 1 is great for practicing:

• straight-line tracking

• gentle turns

• body position and buoyancy

Avoid Fighting the Scooter

Let the scooter do the work. Keep your body streamlined, and don’t try to force sharp turns at high speed—smooth arcs feel better and reduce strain on your arms.

Plan Your Session Around Mode Usage

If you want longer exploration time, treat Level 2 and Level 3 as “tools,” not default settings. Many users get the best overall experience by cruising in Level 1 or Level 2 and using Level 3 briefly when needed.

Charging

The manual lists a charging time of about 4–5 hours, and it also includes important safeguards.

Keep Everything Dry

Never connect the charger if the plug, socket, or charging area is wet. This is basic electrical safety, but it’s especially important around pools, docks, and boats.

Temperature Matters

If the battery temperature is above 48°C / 118°F, charging will not proceed. If the battery has been in direct sun or a hot car, let it cool down before charging.

Understand the Battery Indicator

If the indicator light is rapidly flashing, the battery is below 20%, and it’s time to recharge soon.

Cleaning and Maintenance

If you use the MANTA 2 in saltwater or sandy areas, cleaning is not optional—it’s what keeps the scooter performing smoothly.

The Best Routine

1. Soak in fresh water for a few minutes after use.

2. Rinse thoroughly with fresh water.

3. Dry it before storage.

Salt crystals and fine sand can cause the propeller area to feel rough or tight. Pool chemicals like chlorine can also contribute to long-term wear if you don’t rinse them off.

Don’t Use Harsh Cleaners

A clean, damp cloth is enough. Strong chemicals can damage surfaces and seals over time.

Storage Tip

Avoid leaving the scooter in direct sunlight for long periods. Heat is hard on batteries and plastics. Store it in a cool, dry place.

FAQs

Will the MANTA 2 sink?

According to the manual, it will not sink and should be slightly buoyant.

Is it waterproof?

The manual notes the battery, motor, and internal connector areas are designed for water use, and it also mentions that water can enter the body during operation. The key is proper post-use rinsing and drying, especially after saltwater use.

The motor stopped spinning what happened?

If sand, salt crystals, or debris restricts the propeller, the manual suggests soaking the unit in water for a few minutes and then restarting repeatedly until it returns to normal operation.

All four battery indicators are flashing does that mean it’s broken?

The manual describes a reset-like behavior: release the control and wait for the indicator lights to turn off; it should return to normal.

Will it slow down gradually as the battery drains?

The manual notes that speed remains steady until power cut-off rather than gradually slowing over time.

A Simple First-Session Plan

If you want a smooth first experience, try this:

1. Start in shallow water where you can stand.

2. Unlock the switch lock and start with both triggers.

3. Cruise in Level 1 for 3–5 minutes to get comfortable.

4. Move to Level 2 briefly, then return to Level 1.

5. Save Level 3 for short bursts only once you feel in full control.

6. End your session with a fresh-water rinse and dry storage routine.

Final Thoughts

The MANTA 2 Sea Scooter is built to help you explore more comfortably whether you’re snorkeling along reefs, practicing freediving, or just enjoying a new way to move underwater. The best experience comes from using the safety lock consistently, starting slow, keeping connectors dry, and rinsing after every session especially after saltwater. With those habits, you’ll get more consistent performance, fewer surprises, and a scooter that stays ready for your next ride.
