I have been looking around and some spotlights that mount to your scope so you can turn it on to look for yotes at night. I currently just have a hand held spot light that has three interchangeable lenses from blue to red to orange. Most of the scope mounted lights are red. my question to you all is, is a scope mounted light really nessiciary or will my hand held do just fine? also what do you recomend for a scope mounted light and how well does it work?
