Where these two actually differ
- We flag Polycarbonate optical clarity degradation (UV/thermal), Seal and gasket material composition (PFAS in elastomers), Microcracking of polycarbonate under thermal cycling and Gasket compression set and hydrolysis over years on the GoPro and not on the Think Tank Photo.
- We flag Undisclosed water-repellent coating chemistry and Coating degradation over time on the Think Tank Photo and not on the GoPro.
- The GoPro is Polycarbonate lens dome, unspecified seals and gaskets where the Think Tank Photo is Ballistic nylon, weather-sealed fabric, metal hardware, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
