Hello,
We would like to set up a big project wich all over the world will be a big market for sports.
*We are looking for a device/machine to make squares on the sport field.
*or maybe a cone can be develop to make laser light from cone to cone

It is for outside on the sporting fields so the laser has to be very clear to mark the lines (we think 40m lines of 8cm width? ? ) and the height is for marking the ground. The laser should mark a square were the players can train in (see pictures).
Normally all over the wordl they use cones to mark a field (all the sports). Our idea is to use laser for this (has to be safe for the eyes). Then you see the square better.

And would be more great to develop like a APP were you can enter the sizes of the square and the machine shows this on the field.

Looking forward to your quick reply.

Best Regards
