I use it all. Fishing Tournaments, I caan make one pass down a bank line, and see anything that might hold fish with my SI. Once I locate the structure, and pull up, over the top and look right into the brush pile and see if there are any fish there. Lowrance is a little more expensive, but for me it was only $200. I bought the HDS-10-SI Base Package, HDS-7-SI, and LSS-1, and only cost $200 more than HB. But I shopped the enternet, looking for best price for a month before I bought. Typically lowrance is about $500-$600 more if you don't get seroius on the searching. But it think it is still worth it in the BETTER Imagaes you will get from Lowrance. JMO
