Hi there. New here obviously. I'm just after some recommendatiions. I work on a film set so pointers are very useful for indicating things that are often far away. I would like a pointer that can indicate say up to 200 meters away. Preferably in daylight conditions if possible. As film sets are busy places I am also mindful of accidental shining in someone's eye. Although I'm always mindful when using one I would rather be safe than sorry, So I'm asking for a recommendation for the strongest one in mw I could get that should still be safe around people. Also what colour is most visible? Is it green? And lastly any recommended websites to purchase from. Thanks for any advice you may have.
