Muito bom este teste, não vejo a hora que entre no mercado para proteger os trabalhadores deste risco.

This is terrific! I have an airstrip and there are high voltage wires 8m high and 20m beyond my strip that need to be marked with yellow 600mm diam aviation marker balls. Various contractors have quoted around $4000 to shut down the power and install large marker balls using a scissor lift. Using your method would be much cheaper. Can you install for me please?
