Tether Tools TetherBoost Pro

The TetherBoost Pro System provides consistent power to maintain a stable connection for tethered image transfer when using a DSLR or medium-format digital back system connected to a computer via USB 3.0 cables - now at distances up to 65 feet. This streamlined solution alleviates current frustrations among photographers experiencing dropped signals when shooting with USB 3.0 cameras and computers.

The TetherBoost Pro System alleviates a common problem amongst USB 3.0 camera and digital back users who are experiencing dropped tethering connections or are unable to get a tethered connection started at all. These challenges are affecting some of the most popular cameras on the market, including USB 3.0 cameras from Nikon, Canon, Phase One, Mamiya Leaf and Pentax.

The core issue is that computer manufacturers, often in an attempt to be as efficient with power as possible, are either under-powering or dynamically-powering their USB 3.0 ports. These manufacturers are not currently considering the unique needs of photographers and this is causing these connectivity issues.

The TetherBoost Pro conditions the line and regulates the power from DSLR/Digital Backs to the computer, eliminating these limitations and allowing your tethered connection to operate up to full USB3 speeds for tethering connections from 15 to 65 feet without any loss in signal. The TetherBoost Pro also features the TrueConnect LED indicator which ensures signal connectivity between a photographer's DSLR, Mirrorless or Digital Back camera and a computer.

Included in the TetherBoost Pro Kit is a JerkStopper Extension Lock, an effective locking device that keeps cable ends protected from frustrating disconnects, damage and electrical hazards. The simple clam-shell design enables you to close the JerkStopper Extension Lock around each end of the TetherBoost Pro and USB 3.0 cable, then twist to lock the cords securely and safely together. The JerkStopper Extension Lock comes with two included rubber washers that waterproof your connection, further protecting your connection and holding the cable in place.

The TetherBoost Pro can be used with or without external power and will facilitate producing a reliable connection either way. However, adding power to the line will reduce the customary drain on camera and computer batteries. The included USB-D/C cable is optional for adding a USB external battery pack (sold separately) or A/C power (adapter included).
