Pelican 1525 Air Protector Case w/Foam Black. Pelican's newest case the 1525 Air Protector Case was specifically designed to protect those most valuable items of yours. With a length and internal width that's tailored to your equipment this case will keep anything from a handheld GPS to a professional-grade digital camera safe and secure. This smaller-sized case features an automatic purge valve so any air pressure buildup is automatically equalized. This case was also built with a double-wall rigid frame that provides the perfect base for many soft-case accessories (like an iPad or tablet) as well as a padded base that fits most cases with wheels. If your item is large enough that it needs extra protection the Automatic Purge Valve is a nice touch and the single piece handle with metal lugs completes the professional look.
