Any one shooting through hull?

[tsubaki]

I remember reading years ago of the thru hull difficulties and hope the newer transducers can overcome the old problems. The instructions said to locate it where the glass appeared the most consistant and no air voids (usually the bilge area). Also go as far as to make a container filled with mineral oil that contacted the hull or apply a sealant to the transducer and glue to the hull (again have no air voids).
