-Built-in CHIRP Sonar delivers greater sensitivity, improved target resolution and superior noise rejection for clearer, easy-to-see bait fish and game fish targets. It also delivers multiple CHIRP and Broadband Sounder frequencies from a single transducer.
-Built-in StructureScan HD sonar imaging allows you to enjoy picture-like 180-degree views of structure and fish below your boat. (Requires optional StructureScan HD transducer.)
-Built-in Broadband Sounder displays and marks gamefish, baitfish and structure at higher speeds and at greater depths - from 1 to over 3,000 feet.
-DownScan Overlay technology overlays DownScan Imaging onto CHIRP Sonar or BroadBand Sounder.
-TrackBack to review and save key hotspots. You can scroll-back thru sonar or StructureScan HD imaging history to review structure or fish targets and pinpoint the location with a waypoint.
-SpotlightScan Sonar ready – optional add-on delivers a new level of angler-controlled surround-scanning view to provide picture-like images of key fishing areas.
-StructureMap HD capability – Use live or recorded StructureScan HD logs to create stunning underwater images of lakes, rivers or seafloor. StructureMap can be viewed as an overlay, and toggled on and off to provide the ultimate in situational awareness in relation to both chart and bottom detail.
-Plug-and-play compatible with add-ons such as SpotlightScan Sonar, Broadband Radar, SonicHub Marine Audio, SiriusXM Marine Weather and audio, Class B AIS and DSC VHF, as well as, the recently released SmartSteer control for MotorGuide Xi5 electric-steer trolling motors and the Lowrance Outboard Pilot.
-Internal GoFree cloud enabled, so you can download and upload maps, software and apps direct to your HDS Gen3 (requires software update).
-Connects and communicates with HDS Gen2 Touch and HDS Gen2 multifunction displays
-Dual Ethernet networking port
-Micro-C connection for NMEA 2000 devices
-Video input via optional adapter cable
-Same flush-mount cutout and bracket as HDS Gen2 Touch
-Dual microSD-card slots
-Lowrance Advantage Service program
If the fish doesn't pass directly through the center of the cone, the arch won't be as well defined. Since the fish isn't in the cone very long, there aren't as many echoes to display, and the ones that do show are weaker. This is one of the reasons it's difficult to show fish arches in shallow water. The cone angle is too narrow for the signal to arch.
Remember, there must be movement between the boat and the fish to develop an arch. Usually, this means trolling at a slow speed with the main engine. If you are anchored or stopped, fish signals won't arch. Instead, they'll show as horizontal lines as they swim in and out of the cone.
Actual On-The-Water Chart Recordings
The following chart records are from a Lowrance X-85 liquid crystal graph sonar. It has 3000 watts of transmitter power, a 240 x 240 pixel screen and operates at 192 kHz.

Each HDS-9 also comes equipped with integrated CHIRP Sonar, Broadband Sounder, StructureScan HD, DownScan Imaging and Trackback features. This hi-tech generation advances the award-winning Lowrance target separation by combining simultaneous use of cutting-edge CHIRP sonar technology and advanced StructureScan HD sonar imaging to produce unparalleled views of fish holding near the bottom and around structure.
This appointment was the pre-op appointment. Dr. Lowrance and the nurse practitioner both spent time explaining options, results of tests and treatment options. Our questions were answered and we left feeling prepared for the next day.
