A laser rangefinder module adds distance measurement to a thermal scope that didn't come with one built in. You range the animal, read the yardage, and make a better call on holdover before you squeeze. For coyotes crossing a bean field at night, guessing distance is how shots go wrong.
Here you'll find add-on laser range finder modules from InfiRay Outdoor:
Start with compatibility. A module is designed around a specific scope family, its mounting and its connection, so it has to match what you own. The ILR-1200 is listed for the BOLT AC80. For the ILR-1000-2, confirm your scope model with us before you order. If you'd rather have a handheld unit with the rangefinder built in, look at our thermal monoculars with LRF.
Each module works as an infrared laser rangefinder: it sends out a pulse you can't see and times how long it takes to bounce back. Questions about fit? Call (309) 781-8421 and talk to someone who knows these optics.
The one that fits your scope, because a module that won't mount or connect to your optic is worth nothing at any price. If you shoot a BOLT AC80, the ILR-1200 is the module listed for it. For other scopes, check the ILR-1000-2's compatibility with us first.
Very accurate at normal hunting distances. A good unit typically reads within about a yard on a clear, reflective target. Accuracy drops on small, dark or angled targets, in rain or fog, and when your hands shake, so range something solid near the animal if you can't get a reading on the animal itself.
It varies by model, and the rated maximum is usually measured on a large, reflective target. On an animal, expect less, since fur absorbs more of the beam than a barn wall does. Check each module's product page for its listed range, and treat that figure as a best case.
They do. The beam spreads as it travels, so less light hits the target and even less comes back to the sensor. Air, dust, rain and fog scatter it further. That's why a rangefinder that reads a tree line easily may struggle on a coyote standing at the same distance.
