You've asked some very legitimate questions, thank you. The Slinger weighs a total of 33 lbs. It is no trouble to carry 2 of these by gripping them on the bottom of the "U" with your arms through between the riser arms. They balance real nice. The distances the Slinger throws are dependant upon the knob you put the rings on when you stretch the rubbers down. The standard is with the rings all the way down on the knobs that hold the riser arms on. In the (SRS) Super Retriever Series, where they used all Avery ATB's (like Dokken mallards) there were several marks thrown 25 ft. high and 30-35 yards. I've thrown mallards 20 feet high and 20 yards, sufficient for marks at most all distances. The elevation and distance of marks is adjustable with a hand knob from straight up to about 30 degrees above horizontal. In the SRS, they carried as many as 6 in the back of a Polaris.
