What are the dimples/indents on RFX MEAT?

The dimples/indents you see on your RFX MEAT are normal and expected to be there. 

The dimpling is an enhancement that improves both the manufacturability and the durability of the RFX probes. It's one of the many enhancements that have been and will continue to be implemented as we continue to find ways to optimize the manufacturing process and the overall performance of the RFX line of instruments.
