DJI Mini 4 Pro vs SwellPro SplashDrone 4+
Specs, camera quality, and ratings compared · Updated 2026
The Mini 4 Pro at $759 and the SplashDrone 4+ at $2,777. A lightweight consumer drone versus a purpose-built marine workhorse.
3-inch sensor with omnidirectional obstacle avoidance, and is the practical US-available choice for recreational boating.
The SplashDrone 4+ weighs 2,430g, is IP67 waterproof, launches and lands on water, and handles conditions that would destroy the Mini 4 Pro instantly.
The price gap reflects completely different design priorities.
Pros & Cons
DJI Mini 4 Pro
- Omnidirectional obstacle avoidance with binocular sensors on all sides. It's the only sub-250g drone with full 360-degree protection
- DJI O4 transmission holds a stable 1080p/60fps live feed out to 4-6 km in real-world conditions, with a theoretical 20 km max
- ActiveTrack 360 re-acquires subjects within seconds after losing them behind obstacles like trees or buildings
- 10-bit D-Log M color profile gives professional grading flexibility that rivals much larger camera drones
- True Vertical Shooting physically rotates the camera 90 degrees for full-resolution TikTok and Instagram Reels without cropping
- Waypoint flight mode for repeatable cinematic paths, a feature previously reserved for drones costing $1,500+
- 48MP stills from the 1/1.3-inch sensor produce usable prints and detailed crops
- US availability with full warranty support through Amazon, B&H, and Best Buy
- 20-25 minutes real-world flight time with the standard battery, falling well short of the advertised 34 minutes
- Fixed f/1.7 aperture requires ND filters for bright daylight shooting, and a decent filter set runs $30-60
- Plastic frame feels fragile and picks up damage in minor crashes that heavier drones would shrug off
- Plus battery pushes takeoff weight to 297g, legally requiring FAA registration and Remote ID compliance
- Green lens flare artifact appears when shooting directly into the sun, with no hardware fix available
- 1/1.3-inch sensor struggles more in low light than the larger 1-inch sensor in the Air 3S or Mini 5 Pro
- Wind buffeting causes visible jitter in sustained Level 5 conditions despite the Level 5 rating
SwellPro SplashDrone 4+
- IP67 waterproof and seawater-proof: can launch from water, land on water, and fly through rain without any housing or accessories
- 48MP Sony sensor with 3-axis gimbal produces usable 4K/60fps footage for marine content, fishing footage, and search-and-rescue documentation
- Floats upright on the water surface and can take off directly from waves, which no DJI drone can do
- 7km range with a touchscreen controller gives real working distance for offshore fishing and marine surveys
- Triple-satellite GPS (GPS + Galileo + BeiDou) holds position in coastal winds where single-GPS drones drift
- 2kg payload capacity supports bait release, underwater sonar modules, and life-saving equipment delivery
- 18 m/s wind resistance (35 knots), well above what any consumer DJI drone tolerates
- Modular camera system lets you swap between the G03H filming camera, night-vision GC2-S, or fixed-angle FAC depending on the mission
- $2,777 for the standard combo costs more than a DJI Mavic 4 Pro and produces significantly worse image quality
- 1/2-inch sensor struggles in low light, and the 48MP count comes from pixel binning, not a large sensor
- No obstacle avoidance of any kind means you need visual line of sight and careful piloting around boats, bridges, and cliffs
- 2.43 kg takeoff weight makes it heavy and bulky with no folding design, requiring a dedicated case for transport
- Customer service has a poor reputation: Trustpilot shows 2.8/5 with reports of warranty denials, slow email support, and missing components
- No follow-me tracking mode, so you cannot use it as an autonomous filming drone for water sports
- Unreliable app and firmware update process compared to DJI Fly or Autel Sky
- $150+ batteries and flight time drops significantly with payload attached from the 30-minute rating
Price Range
The Mini 4 Pro costs $759 with full US warranty and DJI Care Refresh availability. The SplashDrone 4+ costs $2,777, nearly four times more.
The Mini 4 Pro with DJI Care Refresh water damage coverage ($49/year, two replacements at $49-99 deductible) gives you budget insurance against water incidents for far less than the SplashDrone's base price.
The SplashDrone doesn't need insurance against water contact because water is its native operating environment.

Camera and Smart Features
3-inch 48MP sensor, shoots 4K/100fps, and has omnidirectional obstacle avoidance with ActiveTrack.
The SplashDrone 4+ has a 4K camera on a stabilized gimbal but no obstacle avoidance and limited smart flight modes compared to DJI's system.
Waterproofing
The SplashDrone 4+ is IP67 waterproof. It launches from water, lands on water, floats, and survives submersion. The Mini 4 Pro has zero water resistance, and any water contact is likely fatal. This is the defining difference between the two.
Size and Portability
- Weight: 249g (Mini 4 Pro) vs 2,430g (SplashDrone 4+)
- Flight time: 34 minutes (Mini 4 Pro) vs about 30 minutes (SplashDrone 4+)
- The Mini 4 Pro folds into a jacket pocket
- The SplashDrone 4+ requires a dedicated carrying case the size of a small suitcase
Choose the DJI Mini 4 Pro if:
- You're a recreational boater who wants aerial footage without a specialized drone
- You need ActiveTrack to follow your boat from the air
- Portability matters (249g vs 2,430g)
- You want a better camera and smarter flight modes
Hand-launch from the deck, let ActiveTrack follow the boat, hand-catch on return. Add DJI Care Refresh for water damage insurance. Just keep it away from the water.
Choose the SwellPro SplashDrone 4+ if:
- Your work requires the drone to operate in or on the water
- Commercial fishing, offshore inspections, or marine research are your use cases
- The drone will regularly contact water during normal operations
- Surf photography from the waterline is part of your workflow
The price is justified when the alternative is repeatedly replacing $759 drones that fall in the ocean.
Our Verdict
The Mini 4 Pro at $759 for recreational boating and casual water sports filming. Better camera, smarter tracking, vastly more portable, US warranty. The SplashDrone 4+ at $2,777 for professional marine operations where water contact is expected and unavoidable. Different tools for different relationships with water.
