PROLINE PLUS Rail-mount teleprompters come completely assembled and ready to use right out of the included padded carry case. Just add your 15mm mounting system (with camera). When you are done prompting the beam-splitter folds flat for instant breakdown. The monitors are self-reversing and can display prompting with the included Pro Version PC and Mac software or use an app like PowerPoint, our monitors do the flip for you. PROLINE PLUS teleprompters ship pre-assembled with standard beam-splitter shipping in a padded carry case, with wireless controller, Pro PC and Mac software on USB and a free download is available at no extra charge. Our exclusive sled design allows the camera rail to be quickly removed for easy storage and travel. PROLINE PLUS 15mm Rail-Mount models can be used as a Free Standing just by removing the 15mm Block extrusion and adding a stand and adapter, or as a Sled Mount by adding the long Sled to the Back of the Teleprompter with the Lowboy and (If needed) riser.
