This DGX bag is well padded and big enough for the Shearwater Petrel or Perdix, the Dive Rite Nitek Q, Hollis DG03 and many other popular computers on the market today(not big enough for the NERD). It also works well for many handheld gas analyzers like the Palm O2 and Palm CO. Inside the bag is a vertical elastic holder for extra batteries or adapters as well as a clear vinyl pocket on the inside flap for identification or small accessories such as the Perdix bluetooth dongle, USB stick or spare o-rings. The heavy padding provides impact protection with a sturdy Velcro closure (no zipper to break, corrode or jam). The design allows for good airflow which assists with drying and eliminates issues that arise from putting a wet computer inside a sealed bag for extended periods. Approximate interior dimensions of {4.5 in x 2.5 in x 4 in deep | 11.4 cm x 6.3 cm x } and overall dimensions of {5 in x 3 in x 4.5 in deep | 12.7 cm x 7.62 x 11.4 cm}
