Where these two actually differ
- We flag Rubber seal (O-ring) degradation, Impact and stress-cracking of polycarbonate housing and Optical material contamination (internal surfaces) 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 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 →
