what is the difference between a Transverse and a non transverse EO tech

Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on June 26, 2023

The EOTech Transverse EXPS2 Holographic Weapon Sight uses a CR123 battery which sits across the optic making it more compact compared to the 500 Series that have the AA batteries sit long ways with the optic. The EXPS and XPS models are all Transverse models.
