First thing you need is to not be afriad to die while you learn
Second you need a decent gunsight with horizontal ticks lined up under the point of aim (center) of the sight. The one I use along with several other verra nice ones are in the gunsight gallery on the AH website.
Then do a search on this board for JABO. Myself and several others have posted many films going in and deacking a field. Several people have posted films on this board to help others learn JABO.
Then go at it (offline if you're worried about score
). It takes practice to learn which tick to line up depending on dive angle and which sight you use. Basically the steeper the dive angle, the closer to the center of the sight your POA is. The shallower the angle, the farther from the center of the sight the POA is. Some runs I've done the proper drop point is just as the intended target disappears under the cowling of me hawg.
