The most streamlined and easy to use multi-pin 

• The UV3XL - 3 Pin Hunting Kit comes with everything you need to start shooting. Everything is pre-installed (including batteries) so all that you have to do is mount it and go.
• The installed 3 Pin cartridge comes with a center-mounted fixed pin for optimum sight picture, 2 adjustable pins, and a bonus pin at the bottom of the housing if you need more distance.
• The adjustable pins are seated in a channel to ensure a non-binding finite adjustability while also preventing the pins from moving when you tighten them back down.
• The 3 Pin is machined from high-grade aluminum and is all self contained within the scope cartridge -- so it's streamlined with no added bulk.
• The centered fixed pin allows you to easily swap between single and double pin cartridges without losing your central mark.
• The UV3XL - 3 Pin Hunting Kit comes with all the same features as the UV3XL Hunting Kit: it has 10 brightness levels, 5 individual LED’s for optimal brightness, auto off (after 4 minutes), allows you to light up your level and is 100% waterproof. To light up your level, hold the power button for 2 seconds.
• Over 6hrs of battery life at 80% brightness.
