i concur with the second poster, i was able to replicate the OP's results but found that level 0 Sonar is only a 100% damage bonus

using snipetron body shotting level 1 Lancer:

150 unmodified hit, 375 hit with level 0 Sonar and 25% Focus, 750 hit with level 3 Sonar and 0% Focus, 937 hit with level 3 Sonar and 25% Focus

a damage bonus of 100% / 200% / 300% / 400% for level 0 / 1 / 2 / 3 correspondingly would seem logical
