Harvesttech H2O precision moisture meter?

Looking to add a moisture meter to my "new" BR7070 crop cutter so I can know when to use preservative, and for piece of mind. Not many options out there. Because I do a lot of baleage my NH dealer was telling me about the harvesttech system which will read up to 60% moisture which is the highest of anything else I've looked at. Dealer is telling me it is more accurate than the agratronix bht-2? Anyone have any experience with the system good or bad? Downfall of it is the cost from what i can see.
