Guide TD633L 640X512 Thermal Monocular 35MM 2X Laser Rangefinder
SKU:
Description
The Guide TD633L is a wide-field 640 thermal monocular with a built-in rangefinder, a value handheld for timber and close cover.
It runs a 640x512 12-micron sensor and 35mm lens at 2x base magnification with a built-in laser rangefinder and a 1280x960 display, 20mK NETD.
Thermal reads heat, not light, so a monocular works in broad daylight as well as full dark. By day it picks game out of thick brush, shade, and tree lines where a regular optic sees nothing; after dark it lights up the whole field by body heat.
A handheld scanner is the piece most hunters reach for first: scan a field, a tree line, or the timber to LOCATE game before you ever shoulder a rifle. Great for spotting raccoon (coon) and squirrels up in the trees, picking out feral hogs, coyotes (yotes), bobcat and fox across a field, checking livestock and property, and finding downed game after the shot. Pairs with any rifle setup, no mounting needed.
Which Guide monocular is right for you?
The TD-series is the value 640 monocular with a built-in rangefinder on a standard display. The 35mm TD633L gives a wider field than the 50mm TD653L, better for scanning timber up close; the 50mm reaches farther. Step up to the Kodiak TK for a QHD display and lower NETD, or down to the compact TE-series.

Common Questions
Does a thermal monocular work in the daytime?
Yes. Thermal sees heat, not light, so it works day or night. In daylight it's deadly for finding game bedded in thick cover or shade.
Is it good for coon and squirrel hunting?
Yes. A handheld thermal is ideal for spotting raccoon and squirrels up in the trees and tracking them at night, then locating them again for the shot.
Does it have a built-in rangefinder?
Yes, a built-in laser rangefinder is integrated, so you can range what you spot without a separate device.
Can I mount it on a rifle?
No, this is a handheld scanner, not a weapon sight. Use it to locate game, then make the shot with your scope. It pairs with any rifle setup.
Guide vs Pulsar or ATN, how do they stack up?
Guide builds the same 12-micron sensors found in units costing far more, which is why hunters pick them for the value. Call us and we'll compare honestly.
