Selling- Caldwell Ballistic Precision chronograph with Photo Logic tripod. The chronograph runs on two 9 volt batteries. ( included ) It measures velocity in both feet per second and meters per second. The Photo Logic tripod features quick release and a built in balancing bubble. It expands to 60 inches. Note- the plastic height adjustment knob is broken but I just use my fingers to raise and lower the height adjustment. * Reduced, now $125.00, plus shipping. Sorry, no trades or CODs. E-transfer preferred.
