CZI TH4 V2 Throwing Hook
The CZI TH4 V2 Four-Stage Aerial Throwing Hook brings precision payload release to search and rescue, emergency response, and remote delivery operations, enabling Matrice M300, M350, and M400 crews to deliver critical supplies to four separate locations in a single flight - without landing.
- Four independent payload releases per flight - Each hook operates independently, allowing operators to deliver to four separate targets or locations in a single sortie without returning to base between drops.
- 2.38kg per hook, up to 40kg total capacity - Meaningful delivery weight for first aid kits, lifelines, radios, and emergency supplies, with a total 40kg system capacity across full multi-flight deployments.
- DJI Pilot App control - no third-party hardware required -- Mounts via DJI SkyPort V2.0 and is automatically recognised by the DJI Pilot App, with on-screen status alerts and release confirmation built in to the interface your crew already uses.
- 310g system weight with anti-mis-drop safety mechanisms - Minimal impact on aircraft flight time and payload capacity, with multiple retention safeguards preventing accidental release before the operator commands the drop.
Overview and Who It's For
The CZI TH4 V2 is a four-stage aerial payload release system designed for the DJI Matrice M300 RTK, M350 RTK, and M400 RTK via the DJI SkyPort V2.0 interface. It mounts directly to the aircraft without tools, draws power from the SkyPort connection with no external battery required, and integrates natively with the DJI Pilot App -- automatically displaying a status and control window when connected.
Each of the four hooks operates independently, releasing on operator command through the app. Anti-mis-drop retention mechanisms prevent accidental release, keeping payloads secured until intentionally triggered. A single hook carries up to 2.38kg with a minimum load of 200g per hook, and the system supports up to 40kg total capacity across multi-flight operations.
At 310g, the TH4 V2 adds minimal weight to the aircraft and preserves meaningful flight time and payload headroom for concurrent sensor or camera payloads.
Note: Payload drop operations in Canada are subject to Transport Canada regulatory requirements. Contact our Solutions team before planning any drop operation. See Regulatory and Compliance below.
Best suited for:
- Public Safety and Search and Rescue -- Delivery of lifelines, flotation devices, first aid kits, and communication gear to individuals in locations inaccessible to ground crews
- Law Enforcement -- Remote deployment of marking devices, communication tools, or tactical payloads in scenarios where ground access is not possible or safe
- Forestry and Remote Field Operations -- Supply delivery to crews in terrain that is inaccessible by vehicle or too time-sensitive to wait for ground transport
- First Nations and Indigenous Communities -- Emergency supply delivery to remote communities where road access is limited or seasonally unavailable

Training and Certification
Operating the Matrice M300, M350, or M400 RTK in Canada requires a valid Advanced RPAS Pilot Certificate. Payload drop operations may require additional Transport Canada authorisation depending on the nature and location of the mission.
Candrone Academy offers online ground school and exam prep for pilots looking to get certified or upgrade to Advanced.
For teams deploying this system in public safety or professional contexts, Advanced RPAS Certification unlocks operations near people and in controlled airspace commonly required for municipal, SAR, and emergency services use.

FAQs
Can the TH4 V2 be used on any DJI drone? No. The TH4 V2 is compatible exclusively with DJI Matrice M300 RTK, M350 RTK, and M400 RTK via the DJI SkyPort V2.0 interface. It is not compatible with consumer or prosumer aircraft.
How does the operator trigger each release? Releases are triggered directly through the DJI Pilot App. The TH4 V2 is automatically recognised when mounted, displaying a status and control window in the app that provides live feedback and release confirmation for each hook.
What types of payload can be delivered? Any payload between 200g and 2.38kg per hook that can be secured to the hook mechanism. Common applications include life rings, first aid kits, throwable communication devices, rope lines, and emergency supply packages.
Does dropping payloads require special authorisation in Canada? Yes. Payload drop operations are subject to Transport Canada regulatory oversight and may require a Special Flight Operations Certificate (SFOC) depending on the nature and location of the mission. Contact our Solutions team before planning any drop operation.
Can all four hooks be released simultaneously? Each hook operates independently and is released individually on operator command. Contact our team if your mission profile requires simultaneous multi-hook release for clarification on operational capability.
