F4 CROSS LINE LASER

The F4 Cross Line Laser Putting Aid is a great tool for helping to technically improve anyone’s putting stroke. This training aid is conveniently charged by USB power and provides very bright laser lines that give excellent feedback about various aspects of the putting stroke. It is adjustable and will fit onto almost all putter shafts enabling a perpendicular reference line for accurate face angle alignment at address. It then provides feedback during the stroke by showing the player where and how the laser relates to the target line. When the laser stays straight the path will have an appropriate arc and path and the face will then also be square in relation to the path.
