Hey Mike i have the 250 model and my friend has the 350 on mine i can see about 100 yards with the red lens with the 350 Andrew says he can go another 25 yards or so. the main thing is using a decent scope so what we dop now is we buy the under water green lights that attract baitfish hook them up to a 12 volt battery, you can see a good 20 yards around the feeder i had the 100 compact and i loved it but with the red lend as you stated it is hard to see I bought 4 extra 6 volt batteries and extra pigtail connections from optronics as i am constantly turning mine on and off you get around 28 continuous minutes of usage out of them so what i do is i wait till i hear grunts then hit the switch, but as you know most big boars you never hear coming unless you hear a crack of a stick or something
