Key features: Mega

　　Side Imaging (MSI) and Mega Down Imaging (MDI): With these advanced

　　sonar technologies, you can see fish and underwater structures in

　　unprecedented detail. The MSI provides crystal-clear images of what's to

　　the sides of your boat, while the MDI offers an equally clear view of

　　what's directly below. High-Resolution

　　7-inch Display: The Helix 7 features a large, 7-inch, full-color

　　display with a resolution of 800H x 480V. This high-resolution display

　　allows you to view sonar and GPS data in bright, vivid detail, even in

　　direct sunlight. GPS

　　Plotting and Charting: This fish finder also includes a powerful GPS

　　system that allows you to create custom waypoints and track your boat's

　　position with high accuracy. The device comes pre-loaded with Humminbird's

　　basemap, which includes accurate charts for coastal and inland waters in

　　the United States. Dual

　　Spectrum CHIRP Sonar: This feature provides two distinct sonar ranges,

　　allowing you to choose between wide and narrow sonar beams. The wide beam

　　gives you a larger view of the underwater world, while the narrow beam

　　offers a more detailed view of specific areas. AutoChart

　　Live: Create your own custom maps in real time as you fish. With the

　　AutoChart Live feature, you can map depth contours, bottom hardness, and

　　vegetation for any body of water, giving you a better understanding of the

　　underwater environment. Bluetooth

　　Connectivity: With built-in Bluetooth, you can connect the Helix 7 to

　　your smartphone or other compatible devices. This enables you to receive

　　text messages and phone call notifications directly on your fish finder,

　　so you can stay connected even when you're out on the water. Expandable

　　Memory: The device includes a microSD card slot, allowing you to add

　　additional maps or save waypoints and sonar recordings. This expandable

　　memory ensures that you'll always have enough storage space for your

　　fishing adventures.
