Tethered Shooting (Photography)
We've had several photographers come to us who want to shoot tethered, but a 15ft cable just isn't enough to shoot around their subject comfortably.  These longer extensions are the perfect mix, combined with any of our cables works perfectly, especially with our angled mini-b cables (link), which take the stress off of the port in your camera, which means reducing expensive repair costs.  We are recommended by support engineers at most major camera manufacturers.

Works great with interactive white boards
We've found that AV installers can easily fish it through conduit and install it into classrooms for AV equipment, including interactive white boards such as the SmartBoard.  You can also daisy chain them with up to 4 inline.  At that distance, however, we do recommend our version with the powered hub (link) at the end to be sure you can power your whiteboard!

Works with all speeds
Some extenders using Cat 5 or Fiber can limit the speed of USB device that can be used (low speed 1.5Mbps such as keyboards, full speed such as cameras 12Mbps, and hi-speed such as hard drives and almost all newer items 480Mbps).  This long USB 2.0 Extension works with all of them.
