Where these two actually differ
- We flag PFAS in waterproof gasket coatings, Polycarbonate stress cracking and microplastic shedding, Gasket degradation and seal failure and Mold and bacterial growth in stored housings 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 housing, waterproof gaskets/seals 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 →
