Rugged Airtight Waterproof Electronics Box

A purpose-built 17.0 × 11.0 × 4.5 cm (6.68 × 4.32 × 1.77 in) container crafted from high-impact ABS plastic. Its core function is dual-layer protection: external hardness shields against crushing and puncture, while the internal sponge liner absorbs shocks and isolates contents from vibration. The lid employs a compression-fit silicone gasket and twin clasp locks — engineered to hold pressure without leakage, even when submerged or subjected to mud and grit. Ideal for safeguarding smartphones, Bluetooth trackers, SD cards, spare batteries or EPIRB accessories. Widely adopted by UK SAR volunteers, mountain leaders and outdoor educators who rely on predictable, repeatable performance in variable conditions.
