SONIC 48 is almost similar to its brother the ECHO 40, only exception being that this model is made to target even larger groupers with its size of 48mm . For more windy or gusty spots, this model would be a more suitable pick than the ECHO 40 due to its heavier weight of 7.6g. The SONIC 48 features a crank depth of up to 5m; a surefire way to lure out all the giants lurking beneath the surface!
