I have set that I bought and they are made of aluminium.They work telescopic and fold to be about 1 meter long and extended they go to 2 meters.There is 3 legs wich makes them real steady.They are lightweight and painted a brownish colour.Very very good thing to have around.Me and NitroX hunted with a pair of homemade ones wich can be seen on my little photo on the side of my posts.They worked pretty good.
