A thermal day night scope gives you two ways to see through one riflescope: thermal imaging for the dark and full-color viewing for daytime. You don't have to swap optics at last light or pull the rifle down at sunrise. Multispectral scopes go a step further by combining more than one imaging type in a single housing.
The model in this category is the Pulsar Thermion Duo DXP50 Multispectral Thermal Riflescope, which brings thermal and full-color day imaging together on one rifle.
Thermal works at any time of day, because it reads heat, not light. A daytime thermal scope can pick out a bedded hog in tall grass or a coyote against a frosty field at noon. What it can't show is color and fine visual detail, the kind that helps you be sure of your target against brush. That's where a full-color day channel helps. You switch to it to confirm what the thermal found, then go back to thermal when light fades.
When you weigh a thermal and daytime scope against a dedicated thermal, look at weight, battery runtime and how quickly you can switch modes. If digital night vision with a color day mode suits your hunting better, see our digital day/night scopes.
There is. Multispectral riflescopes like the Pulsar Thermion Duo DXP50 combine a thermal channel with a full-color day channel in one optic. You run thermal after dark, switch to color in daylight, and keep one scope on the rifle through the whole hunt.
You can. Thermal reads heat, so it works in full sun as well as darkness, and it's good for spotting animals in shadows, tall grass or timber edges. On hot afternoons the contrast drops as the ground warms up, which is one reason a full-color day channel comes in handy.
Night is where thermal does its best work. It needs no light at all, since it builds the image from heat given off by animals and the ground. Coyotes and hogs stand out bright against a cool background, even on a moonless night with heavy cloud.
In many states you can, since coyotes are often open year-round with night hunting allowed. Rules differ on seasons, private land and which optics are legal, so check your state's regulations first. A thermal scope lets you identify a coyote at distance and follow it as it circles the call.
