The new FL-22 HD Pro Pack II starts with its ability to match the output pulse length with each depth range making for an ideal balance between target ID and display resolution. This is a first with any flasher sonar and since it delivers the best possible resolution at each depth range, you are able to see more detail and understand more about what is going on below. The FL-22HD also has a built-in low power mode, ideal for fishing in heavy weeds and still spotting your fish targets. Two zoom zones that target the bottom 6 or 12 feet of the water column. It also offers a 6 foot Bottom Lock feature for use during the open water season. All of this with target ID down to 1/8 inch, built in night mode and now consumes 25% less power to last longer on a single battery charge.
