Lowrance Low/High CHIRP TotalScan Thru Hull

The Lowrance Low/High CHIRP TotalScan Thru Hull transducer is the all-in-one sonar solution serious anglers and boaters demand when they need to see what's beneath the surface. Whether you're working shallow flats, deep offshore structures, or searching for suspended fish in transition zones, this through-hull transducer delivers the imaging clarity and frequency versatility to locate fish faster and fish smarter. Built for tournament anglers, charter captains, and recreational boaters who refuse to compromise on sonar performance, the TotalScan combines multiple imaging technologies in a single installation.

This transducer operates across dual frequency bands—50/200kHz Broadband sonar and proprietary CHIRP technology—allowing you to adapt your sonar presentation to water conditions and target behavior. The 455/800kHz down and side-scan frequencies provide the StructureScan HD and DownScan Imaging capabilities that reveal bottom hardness, vegetation, baitfish balls, and structure definition with exceptional resolution. Thru-hull mounting integrates seamlessly into most fiberglass hulls, eliminating transom clutter and providing stable, interference-free performance that performs consistently whether you're running shallow or deep. The 6.62-pound sensor weighs little enough for responsive installation yet robust enough to withstand years of salt and freshwater exposure.

Anglers upgrading existing Lowrance systems will appreciate plug-and-play compatibility with compatible Lowrance chartplotters and head units, eliminating the need for expensive reconfiguration. This transducer excels in both freshwater lakes and saltwater environments, making it ideal for anglers who fish multiple venues or operate charter services requiring versatility. Installation requires basic hull preparation and through-hole mounting; professional installation is recommended for optimal performance. The TotalScan Thru Hull is the choice for anyone tired of guessing what's below and ready to eliminate fish-finding uncertainty.
