SwellPro SplashDrone 4+ Enterprise

SwellPro's most capable waterproof platform — built for professional missions beyond fishing. IP67-rated airframe (dust-tight, and rated for accidental submersion to 1 m / 3.3 ft for up to 30 minutes) with self-floating, self-righting PowerFlip design, a choice of three interchangeable sensor payloads (standard 4K, thermal, or 160x zoom), and an optional underwater sonar module for below-the-surface awareness.

Key Features

  • IP67 waterproof airframe with self-floating, self-righting PowerFlip design
  • Up to 7 km (4.3 mi) max flight & live video range
  • Interchangeable camera payloads: G03H (48MP 4K, 8x optical zoom), G04 (thermal + optical dual-sensor with laser rangefinder), or G05 (48MP with up to 160x hybrid zoom and laser rangefinder)
  • Optional underwater sonar module, scans to 40 m / 131 ft in real time
  • Dual payload release — carry to two separate drop sites in one flight, up to 2 kg / 4.4 lb total
  • Up to 29 minutes of flight time per battery (no wind, no load)
  • R03 Pro waterproof touchscreen controller with wet-hand touch support, built-in mic/speaker, and wireless headset support
  • Automatic return on low battery or lost signal, with automatic payload release before return
  • 45-second no-calibration setup

Built For

  • Maritime search & rescue — thermal detection, 1200 m / 0.75 mi laser rangefinding, and a partial-release life ring drop for safer overboard recovery
  • Harbor & port security patrol — long-range zoom for vessel identification and thermal imaging for night operations
  • Hull, bridge & offshore structure inspection — up to 160x zoom and 48MP stills for close-in detail without physical access
  • Environmental & coastal monitoring — underwater sonar scanning alongside aerial imagery in a single flight
  • Law enforcement & evidence collection — one-tap screen recording, remote broadcast via the built-in speaker or an optional megaphone accessory, and footage stored locally with no cloud dependency
