Where these two actually differ
- We flag PTFE/PFAS in waterproof seals and gaskets, Polycarbonate photodegradation and optical haze, Gasket and elastomer degradation over time and Mold and bacterial growth in seals if not dried on the Aquatech 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 Aquatech.
- The Aquatech is Polycarbonate/acrylic housing with waterproof 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 →
