I have a HB Paramount with side find and it works great for hunting down packs of fish. Depending on what model or brand you have will determine how deep down and how far to the side they look. Mine is down to 100ft and 60ft to each side of boat. So i just start out and cut a 120ft wide path down the lake and eventually run into a pack. Very usefull. Great for spot casting to risers. Also great for looking under docks, logs, lillys or just to scan the shoreline.
