So whats to stop someone turning it on & off, how do you police this? Either marshals or shooting buddies ?
I thought if it turns on & off on it's own, it had to stay off ??
I could start off with it written on my card & 'forget' to turn it on, come to a shot that was dark or the ret was hard to see, say' oh, my IR has turned odd' & switch it on..
I personally don't have IR so was just using it as an example.
In life you should not persue goals that are easily achieved, develop an instinct for what can be only just achieved through your greatest efforts.
