If you like the idea of using a thermal imaging rifle scope but don’t want to remove your day scope for a dedicated thermal scope, then you might like the idea of a thermal imaging scope add-on. These attach to the front of your scope to give it thermal capabilities. The Pulsar Core is a very popular product as it can be used as both a handheld thermal spotter and also a front scope attachment; giving you two products for the price of one and versatility for various types of shooting.
