........ it will work . Others have had excellent success in thru haul shooting w/standard transducers .
Best performance is achieved when the haul being shot thru is solid w/o voids or air bubbles in the core . Also the mounting of the transducer must absolutely be a solid voidless connection and the transducer should be clean and smooth (wet sand face w/X-fine if nessasary) . The area you mount to on the haul should be completely smooth as well (smooth it as nessasary) .
Also you check the insulation on the tranducer cable . Repair or add extra jacket if damage or deterioration is seen . The sonar units are very sensitive to electromagnetic interference , and damage cable insulation or being bundled w/other electronic instruments cause static noise in the unit readout .
A silicon bed "is not" the prefered method for the connection mount because the silicon absorbs much of the energy transmitted by the transducer .
A solid (hard) epoxy bedding is the best prefered method . Know that you can sand the face of the transducer at will because it is a "thick" expoxy base material .
For waters up to say 50' depth , a low watt output and wide angle transducer are best . for deep waters like 100'-150' a higher watt output and narrow angle transducer are best .
Also you should smooth the area on the exterior of haul just beneth the transducer if it's scrathed up , etc.
Nothing stupid about the question ... people been doing it and wanting to know about it forever ... it works most of the time for most who do it with the understanding of the objectives in installation .
