In this work, we present the first results of a study of signal discrepancies betweendata and simulations with Golden Hybrid events measured with the SD-750 andHeCo. We follow the strategy of previous works but at lower energies. We see adifference in the signal of the Water-Cherenkov detectors between the acquired andsimulated events of about 25% and 20% for proton and iron initiated showers andQGSJet-II-04 respectively. The observed discrepancy is attributable to the muondeficit in simulations. These results are compatible with those obtained with theUnderground Muon Detector in the same energy range.
