Well-Vu’s Fisheye camera reduces the time spent viewing with a side view camera. It is no longer necessary  to spend 2-3 minutes rotating and panning before moving down another 4-5 inches and starting the rotation all over again. The Fisheye lens allows drillers to look in a 360 degree circle, a full 184 degree horizontal and down view nonstop. The lens eliminates the need for an expensive down view and side view camera. www.wellvu.com/index.html
