What's the difference?

The Gunbox 2.0 & the ECHO have very similar interior capacity dimensions, and nearly 95% of firearms that fit in the 2.0 will also fit in the ECHO. However, the 2.0 is engineered with (2) chromed steel shocks for hydraulic automatic opening. With a force of 35 - 45Newtons the open velocity will consistently be about 1 second. The ECHO much like a standard safe, will unlock and then you open the lid yourself.
