Here are the regs. As I read it if it is not projecting a light it is alright
(i) Except as otherwise provided, while taking or attempting to take big game under the provisions of Section 353 or Section 354, Title 14, CCR, it is unlawful to use any device or devices which: 1) throw, cast or project an artificial light or electronically alter or intensify a light source for the purpose of visibly enhancing an animal; or 2) throw, cast or project an artificial light or electronically alter or intensify a light source for the purpose of providing a visible point of aim directly on an animal. Devices commonly referred to as "sniperscopes", night vision scopes or binoculars, or those utilizing infra-red, heat sensing or other non-visible spectrum light technology used for the purpose of visibly enhancing an animal or providing a visible point of aim directly on an animal are prohibited and may not be possessed while taking or attempting to take big game. Devices commonly referred to as laser rangefinders, “red-dot” scopes with self-illuminating reticles, and fiberoptic sights with self-illuminating sight or pins which do not throw, cast or project a visible light onto an animal are permitted.
Now I know for a fact that the regs use to prohibit any bow mounted lights or lasers but I cant find the lasers in the current regs. When the Leupold Vendetta came out the regs at the time were worded such that they prohibited bow mounted range finders.
