Retired Navy Seal Brandon Minuth brought his "tool box" of devices carried by Navy Seals--including this altimeter.

The Seals are the Navy's Special Warfare Unit.  Brandon brought a video showing the six months of training that Seals receive--the most extensive in the military--at a cost of $3 million for each trainee.  The Seals currently have 2,500 operators deployed in 31 countries around the globe.

The supplies that Brandon brought with him demonstrated the myriad venues in which Seals operate, from underwater to snow-covered mountains to high altitudes.  Clearly those who are willing and able to serve as Navy Seals make the world a safer place for the rest of us.
