OnTarget2! is $25 for the full program.
If you are only interested in the shaft selector program,
the download price is $9.95.
In my opinion,
the owner and the chief programmer Larry Clague
really does not charge enough for all the work that
he puts into his product.
I use OnTarget2! exclusively
to help folks with their arrow length, stiffness, FOC%, KE, broadhead choices, target point choices, etc.
