Lowrance LSS-2 StructureScan HD Review


LSS-2 StructureScan is the greatest leap in fish finding technology ever developed by Lowrance – and it works with all HDS displays. LSS-2 StructureScan takes fishfinding to the next level – bringing you an unprecendented level of clarity, accuracy and imaging detail.

StructureScan combines DownScan imaging and SideScan imaging to bring you the “whole” picture – and you can view it all on your generously sized HDS display – StructureScan takes all the guesswork out of fish finding, so you can spend more time catching!

SideScan imaging with this module will show you detailed, high-res coverage of 600 feet side-to-side – you really will never miss a single thing! Imagine only having to go up and down an area one or two times and seeing everything there is to see!

DownScan imaging with this module will show you highly detailed SONAR readings from right beneath your boat. You will see everything for exactly what it looks like – no more guessing! Once you see a good area from SideScan, you can zoom in on it with DownScan for even more accuracy.


Even though 2D SONAR is really good, it’s still tricky to interpret and understand what’s happening, since everything is just lines, arches, and blobs!

When you combine split-screen viewing with 2D SONAR and StructureScan, you can observe the 2D SONAR readings and collaborate those with StructureScan data to really understand what’s going on!


Installing is really easy! the LSS-2 transducer mounts on your transom like any other transducer, and it won’t interfere with other existing transducers, either.

Run the wire from the transducer into the LSS-2 Sounder Module, and run an ethernet cable from the sounder module into your HDS unit – that’s it! If you have multiple units, you can use a single sounder module for multiple units – just plug and play.
