Just unloading a shipment of Magnetospeed - the picture is a V3. When we first got this product we took one of the V3's to the range. I watched a youtube video of the product. After watching the video I installed the product on 2 different firearms at the range - with people watching. It took me less than 3 minutes per firearm. The next time it will take me 30 seconds. This is the easiest chrono I have ever used.
