Our Equipment

  • WaterShark Harvester

    WaterShark Harvester

    Our flagship weapon: this battery-powered beast cuts and collects the lake weeds for disposal. Lightweight, foldable, and operated from shore with live camera feed, it clears 10,000+ SQFT in 3-4 hours.

  • Weed Rakes

    Weed Rakes

    Heavy-duty, long-handled rakes designed for shoreline crews to pull stubborn rooted milfoil and floating debris. Wide heads and long teeth make quick work of dense patches, perfectly complementing the WaterShark for complete coverage.

  • Weed Razors

    Weed Razors

    Throwable cutters that slice through submerged weeds at the root. Ideal for targeted spot treatment around docks, boats, and swim zones—fast, effective, and effortless for finishing touches.

  • Aerial Drone

    Aerial Drone

    We deploy drones for detailed before-and-after aerial photos, accurate noxious weed identification, and project planning. We see the full scope of infestation from above, track progress, and our customers receive stunning proof of our work quality.
