This article was written for the US marketplace and compares the 2" stock head and the US HR head. The testing also included the Thunder Global HR head but we have omitted that head from this data since it's a legacy product in our territory. You can find the complete test results, along with this version, attached at the end of the article.
We let China Engineering know when we started offering the TL-USA HR Head (Beam Buddy) and we submitted one to them for approval. They thoroughly tested it, as they do with everything, and the results are back. The US HR head exceeded their high expectations.
Here is what they found:
