Appreciate the feedback. Nodal Ninja will certainly last you for many years.
When shooting at longer focal lengths or when you desire less than 15 degree increments simply use the 0 degree side of the 15/0 ring (included as default ring in all NN3 MKII's). In this manner you can reference the 5 degree demarcations on the lower rotator. Can you send a photo of the mod you are speaking?
