The INDURO GHB2 Gimbal Head is ideal for photography involving long, heavy telephoto lenses--in sports or nature photography, for instance. Working with a long lens on a standard ballhead or tilt head can be a real struggle, distracting you from the photography. The gimbal head makes the camera and lens seem almost weightless, with vertical and horizontal tracking of moving objects becoming relatively simple--a feat not possible with any other support system. An Arca-Swiss-compatible quick-release plate is included. Fits size 3 and 4 tripods.
