How to use
Customize the interior using precut pick-and-pluck foam or a padded divider system to securely fit your devices. Place delicate items on the egg crate foam under the lid for extra cushioning. Use the automatic pressure equalization valve when transporting the case by air; it operates automatically and requires no user intervention. Attach optional accessories such as a shoulder strap for carrying, a wall mount for stationary work, or a mounting frame for instrument panels as needed.
Usage recommendations
For best protection, ensure foam inserts are trimmed to fit devices snugly, close the latches fully before transport, and check the seal for debris to maintain IP67 performance. When flying, allow the valve to equalize pressure naturally and avoid forcing the case open until cabin pressure stabilizes.
