my kestral 3500 turned up today i was reading through the manual and it said i needed to reset the altitude at a refrence point to make sure that its corrrect but then it said some ballistics programs need it to b set to zero. so now im confused do i just keep using it as is or do i need to reset it / calibrate it
what ya gonna shoot with that. ya know those deer that are just outta range for you. yeah. well there not 4 me!
