Viper Archery The Charge Rechargeable Sight Light - There are times when both target shooting and bowhunting (where legal) that using a small light to illuminate your sight pin(s) is advantageous. The problem with other sight lights on today's market is they run on small batteries - and as we all know, when your battery runs out of power, you never have a spare handy. Enter Viper Archery's new Rechargeable 3-Stage Universal Sight Light, The Charge, a high-quality product designed around a long-lasting, rechargeable battery. The Rechargeable 3-Stage Universal Sight Light fits thread sizes 1/4-28, 7/16-20, and 3/8-32, and is rechargeable using an included Micro USB cord. Charging time is less than one hour and the light will last for at least four hours on a single charge. It has three stages of brightness - low, medium, and high - so you can adjust it to meet changing conditions. It's waterproof and turns on and off with the press of a single button. At the end of a long day of usage, you simply recharge the battery overnight, and never have to worry about running out of power again.
