This unit includes accelerated real-time sonar and echo enhancement technology for the instant capture of action and the sensitivity to track a jig to over 70 feet, with a target separation of 2.5 inches. The 997c also has an external, 16-channel WAAS/EGNOS GPS receiver, and a built-in UniMap of USA inland lakes, rivers, and coastal areas. This unit's high-speed, micro-dynamic transducer is reliable to 70 mph, and includes water temperature and GPS speed.

The 997c has a brilliant 8-inch TFT LCD screen with 480 x 800 lines of resolution in full color for enhanced separation, and an adjustable backlight. This unit features dual microprocessors and a graphics co-processor for fast, smooth operation, networking capability, and chart recording to SD card with on-screen playback.

This unit measures 11.25 x 6.75 x 4.25 inches (W x H x D) as a Gimbal mount, or when in-dash mounted requires three inches of clearance.
