I'm an e-target manufacturer, so I am far from unbiased. *BUT* the truth is, any system used has its flaws and features. It's not a matter of picking a perfect system (it doesn't exist), it's a matter of choosing an imperfect system that is acceptable, and more suitable for your purposes than the other imperfect systems available to you.
There are some errors that can happen with electronic targets that are very unlikely or even impossible to happen with manually-marked targets.
And vice versa. With manually-marked targets, even with the most honest and attentive and competent target markers, and with the best-designed procedures in place run by a butts officer who knows his stuff, there are ways in which a shooter can be done wrong. I've been on a Match Committee on which we were unable to give the shooter a remedy, and I (and presumably the rest of the Match Committee) think he was done wrong.
To leave e-targets and return to the main topic of this thread, I think what toofar2late has done is fantastic - this new 1600m range is really exciting news and I can't wait for them to be up and running. In fact, I'd love to visit it in person (he says, nervously checking the price of plane tickets from Fredericton to Edmonton, yikes....!)
