Heres mine, i throw bumpers but think it could throw a teal 5 ish yds. I like that i can throw 3 or however many you design it for. It'll throw a bumper 10-15 yds long and 15ft high depending on placement. Peizo mounted to jbox, only negative is I need a car battery to weigh it down to keep from shaking bumpers off the arms. I built 2 of these, used them for 2 weeks then got a sweet deal on 4 max 5000s. Id sell them if antyone was interested.
