Re: [TANKS] New elevate complete
The improved accuracy of Tri-Pact elevate and rotate systems means that there is only one last hurdle towards the goal of extreme accuracy ... finding perfect paintballs. To that end, Tri-Pact has begun development of an electro-mechanical sorting machine that will detect paintballs that are perfectly spherical and have uniform density. When armed with these so-called "Uberballs", effective accuracy should be less than 0.01 mm at a range of 50 meters, tailing off to 0.1mm at 100 meters. PUFF forces will be decimated.
