48" Hexagon 6 pack with Center Eyelet

As described. A little expensive, but well made and they show well in data with a decent quality sensor. Good for LiDAR and photogrammetry. Tough to fit in associated carry bag that I bought separately by the same brand for this set. Glad I went with 48” over 24”.

I’ve purchased hundreds of these for our remote sensing projects. Great quality and fast shipping. We prefer the 48x48 because it’s easier to see in the LiDAR data. I wish they would do away with the center eyelet and make it triangular flaps to the center. That’s what I normally have to rip out the second I get them so my nail doesn’t get disturbed picking them back up.

Professionally, I am a Civil Engineer and I like to use drone technology for mapping. I had a personal mapping project of my property where I wanted to track some progress of trail construction and align it with my property boundary. I was able to situate these at multiple property corners, fly my drone over the area for mapping and clearly see these targets on the ground; even in wooded areas (flew in the winter with no leaves). These specific targets do not have the larger center hole for property pin centering, but what I did was put the 'numbered' square corner up to the center of the pin and then staked down my corners to hold the target firmly in place. This allowed me to fly the property and know that the numbered squares are the corners - which is a consistent way to align the map with my boundary survey. I flew at 185 ft (1.5cm/pixel for DJI Phantom 4) - I have trees I have to clear and 190' of topographic relief on the property). The numbers were very easy to read at this elevation. Since my 185' was fixed, down in the low points of the property, I was over 350' of elevation delta between the drone and target - still readable! I then flew at 235' feet (2cm/pixel) and still readable - at over 400' in elevation to the target. This target was also in a wooded area. The targets are durably made. I can see them lasting for a lot of uses. I can also see that if a construction company wanted to monitor a job site over a period of time, these can likely withstand staying in the field for a few months - they might fade under UV light based upon the material type; but they are inexpensive to replace. You can possibly stake these down with better stakes - or mount to a hard surface with fasteners and even have an elevation target to use. Overall - if you are doing drone mapping, these are a better tool than some of the 'homemade' solutions - especially at the price of plywood materials and paint; I would definitely recommend them. They are inexpensive solutions that provide reasonably accurate results.

Love these targets! Haven’t frayed, ripped, or become less useful in any way. Used roughly under land dev work and still performs. Good ad hoc takeoff/landing pads, too.

Works well for what I need it for. Very lightweight and blows away in the lightest of winds.

Very sturdy and well thought out.

Sturdy and Well Made. Very legible from the air. Each square is exactly 2 ft wide with each color in the square exactly 1 foot wide. Thus if you lay 5 side by side it makes a 10 foot scale for measuring in photos. Used them for planning landscaping with drones.

Perfect delivery and quality

No complaints

Super !!!!

Recomendado, excelente puntos de control para drone, muy buen servicio y rapidez en la entrega, gracias

Seem a little expensive but they'll do the job!

Its made of some kind of mesh. Very good quality and does not take much space as you can fold it. Easy to carry to any projecy
