Guide Orion O435CS 400X300 Thermal Clip-On 35MM 1X
SKU:
Description
🔭 The Guide Orion O435CS is Guide's entry thermal clip-on, the most affordable way to turn your day scope into a thermal rifle scope at night.
It runs a 400x300 12-micron thermal sensor behind a 35mm lens at true 1x, with a 1024x768 display and a 15mK NETD. A light, affordable front clip-on for hunters getting into thermal.
A thermal clip-on mounts in FRONT of your existing day scope and turns it into a thermal scope after dark. It holds your zero, so you do not re-sight anything: clip it on, and your rifle shoots to the same point of impact it always has. True 1x magnification means your day scope still runs the show, dial your normal power and shoot like you would in daylight. Take it off and your scope is back to normal glass. One clip-on can serve every rifle you own.
Which Guide clip-on is right for you?
The Orion O435CS is the entry clip-on: a 400x300 sensor and a wide 35mm field of view at the lowest price, no rangefinder. Step up to the Orion O635CS for a sharper 640 sensor, or the TB650LP / TB1260LS for a 640 or 1280 sensor with a built-in rangefinder and more reach.

Common Questions
Do I have to re-zero my rifle?
No. A clip-on mounts in front of your day scope at true 1x and holds your existing zero, so your point of impact does not change. Clip it on and hunt.
Does it work in the daytime?
Thermal sees heat, not light, so it works day or night. Clip-ons are run mostly after dark, but the sensor reads heat in daylight too.
Will it fit my scope?
Clip-ons mount to the objective bell or a rail adapter. Fit depends on your scope's objective diameter, so call us at 252-431-6001 and we will confirm the right adapter before you order.
Can I use it as a handheld scanner or a rifle scope by itself?
No. A clip-on is built to pair in front of a day scope, not to be used alone. For a standalone unit look at a Guide thermal scope or monocular.
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 will compare honestly.
