I have used this one for the last 25 years, this model comes up on eBay every now and then fairly cheaply, a new one will cost you a bundle. This one gave up the ghost after about 20 years of use but Wagner will refurbish one for about $100 so I sent it back and had it reworked.
I don't use the wood table and am only looking for my bow wood (osage) to reach the ambient moisture level in my area which is 12%, for hickory I will be looking for 8% or less.
In black power we call people who have to have every little thing about their outfits, accruements and firearm perfectly period correct "thread counters".
In bow making we have quite a few thread counters as as well. For me a ball park figure on moisture content that shows me that my wood has stabilized and is ready to work is good enough for me, I don't feel the need to cross reference different wood species to the exact degree as the wood chart would indicate.
The first thing I found out after I got my pinless meter what just how much wood people gave me and told me it was cured and dry was actually as green as a gourd with a moisture contend of 22%+.
