Yeah, have to say that there aren't may that use a tube these days...that said it still gets it done. I've used one, it worked, but was always scared it'd break on a cold morning. So...shot a peep...one that split the string 3 ways. It work pretty well too but have to say there was always a nagging question if it'd come back right at crunch time. It did just about everytime...but the question remained....everytime. Got older...eyes got worse, so have been shooting a timberline "no-peep" w/ both eyes open. Cant say I've lost any accuracy. It gets the job done here on the east coast (way less than 50yrd...more like 20). Even the other day when the no peep went way outta whack (1st time in maybe 8yrs)I still kept everything in a 2" dia. out to 30yds just drawing naturally. So w/ a no peep if it shears off/breaks...no matter. So long as I draw naturally...I'll hit what I'm aiming at out to 30-40yds. It doesn't get more reliable than that..which is why I've stuck with a no peep. ITs an alternative....just not for everyone. Options are good.......
