Sky High Bull's-Eye Drone Ground Control Point GCP - Numbered 10 Pack

In this review we assess the Sky High Bull's-Eye Drone Ground Control Points (GCPs) as a practical kit for field mapping and surveying. The bottom line: these 24' by 24' numbered targets are aimed at drone pilots and surveyors who need quick visual identification and reliable image contrast; the unique numbered centers make matching targets to coordinates easier and speed up processing in mapping software like Pix4D and DroneDeploy. They are especially useful when working across multiple control points and looking for a lightweight, durable solution for everyday GCP placement.

Key Features

• Numbered targets: Each marker is numbered 0 through 9 so operators can quickly correlate individual GCPs with their recorded coordinates for smoother postprocessing.
• High-contrast color: The white and black checkerboard design enhances target visibility and exposure in bright conditions, improving detection in aerial imagery.
• Four corner eyelets: Four reinforced eyelets allow the GCP to be staked or weighted down so it remains stable during windy survey sessions.
• Lightweight and waterproof: The construction is both lightweight for easy transport and waterproof to withstand damp field conditions without immediate damage.
• Practical size: At 24 in by 24 in the checkerboard is large enough to be detected from typical mapping altitudes while still compact for packing and setup.

Who It's For

The Sky High Bulls-Eye GCP 10 pack is best for professional drone operators, surveyors, and mapping teams who deploy multiple ground control points across a site and need to identify each one quickly during data collection and processing. The numbered markers reduce confusion when correlating photos to ground coordinates, which is valuable on multi-target missions.

Less suitable are users who require very large permanent benchmarks or rigid survey monuments; these lightweight, portable GCPs are designed for temporary placement and field convenience rather than long-term fixed installations.

Pros & Cons

Pros

• Clear numbered identification speeds workflow when using mapping software like Pix4D and DroneDeploy.
• High-contrast white and black pattern improves visibility and image exposure from altitude.
• Four corner eyelets make it straightforward to secure the target in breezy conditions.
• Lightweight, waterproof material makes transport and field use hassle-free.

Cons

• The 24 in size is ideal for many missions but may be small for extremely high-altitude flights beyond typical mapping heights.
• As a soft, portable marker it is not a substitute for permanent, rigid survey monuments where long-term stability is required.

Our Verdict

For drone survey teams who need a simple, portable solution to speed target identification, the Sky High Bulls-Eye 10 pack delivers clear value through numbered targets, strong contrast, and convenient securing points. It is a practical, cost-effective kit for routine mapping work, though operators needing permanent monuments or much larger targets for extreme altitudes should consider other options.

Frequently Asked Questions

Can these GCPs be used with Pix4D and DroneDeploy?
Yes, the numbered targets are designed to be compatible with Pix4D, DroneDeploy and similar mapping software to simplify matching targets to coordinates.

How visible are the targets from altitude?
The 24 in checkerboard and white/black contrast are visible at common mapping altitudes; customers reported clear visibility from around 400 ft in typical conditions.

How are the targets secured to the ground?
Each marker has four corner eyelets so you can stake or weight them down to prevent movement in wind.
