Performance
The 904 delivers serious protection in a portable footprint. Its NK‑7 resin body resists impact and withstands -29 °C to 60 °C temps, while the PowerClaw latches and gasket maintain a reliable seal—even when submerged or air-transported. The ergonomic handle and lid-stay hinge open easily when uneven or tradewind-blown, and the float capability adds extra field value. Interior customization is possible via optional foam inserts or lid bezels (.pdf available) ().
