I've been a furniture and cabinet maker my whole career, so far 42 years worth. I've made a few stringed instruments and milled and sold material for quit a few makers more skilled than I am. I've developed the habit of listening for dryness by knocking with my knuckle or scratching backwards with a fingernail. Been a woodburner for a long time so I am ahead on wood and I also have a pretty good idea of how long it will take to dry, but I still find myself "scratching" the latest batch of splits. It might be worth a try. The splits can be stacked or in a pile. Try raking a fingernail backwards across the growth rings. Dry sings and moist is dead and all kinds of tones in between. A moisture meter requires a great deal of dedication and experience to be of real value. Highly dependent on temperature, relative humidity, and interpretation. The best use of a meter is to have a known dry sample of the same species to stick for comparison and under the same conditions. Just my ideas.
