Spin-exchange pumped noble gas comagnetometers consist of two or more co-located ensembles of noble gas atoms whose nuclei are polarized by spin-exchange collisions with polarized alkali atoms. Such devices been used to place upper bounds on fifth forces and Lorentz violations and for the measurement of inertial rotation. In this talk I will discuss some of the systematic errors generic to spin-exchange pumped comagnetometers. I will also describe the design and performance of a novel comagnetometer which suppresses these errors.
