The ^{12} ${}^{12}$ C Hoyle state is a candidate for \alpha $\alpha$ -condensation, due to its large volume and \alpha $\alpha$ -cluster structure. This paper discusses precision break-up measurements and how they can elucidate \alpha $\alpha$ -condensate structures. Two experiments are discussed in detail, firstly concerning the break-up of ^{12} ${}^{12}$ C and then the decays of heavier nuclei. With more theoretical input, and increasingly complex detector setups, precision break-up measurements can, in principle, provide insight into the structures of states in \alpha $\alpha$ -conjugate nuclei. At present, such searches have not delivered evidence for \alpha $\alpha$ -condensation in ^{12} ${}^{12}$ C or ^{16} ${}^{16}$ O.
