Make the Helix 7MSI portable with this bundle. The lightweight 10Ah Lithium Battery will power the Helix for your day out on the water. Great for Kayaks,  fishing hire boats or small day boats without a 12v system.

The HELIX 7 CHIRP MEGA SI GPS G3N fish finder features MEGA Side Imaging, MEGA Down Imaging, Dual Spectrum CHIRP Sonar, Ethernet networking capability, Bluetooth, AutoChart Live, GPS and Humminbird Basemap built-in. The 7", ultra-wide display gives you ample room to view the many pre-loaded split screen view options.


NEW to HELIX 7- MEGA Side Imaging: See the world below like never before with crystal-clear viewing out to 125 feet on either side of your boat. You'll unlock new details with up to 3X more output than standard Side Imaging sonar.

NEW to HELIX 7- MEGA Down Imaging: Get unprecedented underwater clarity with coverage down to 125 feet below your boat. You'll unlock new details with up to 3X more output than standard Down Imaging sonar.

Dual Spectrum CHIRP: Before you cast, know what's down there thanks to long, well-defined fish arches, and a clear view of fish-holding structure and the bottom. Powered by our proprietary, Low Q CHIRP transducer, Dual Spectrum offers two ways to search: wide mode for maximum coverage and narrow mode for maximum detail.

SwitchFire Sonar: Take command of how your sonar returns appear. With two display modes, you can add or remove detail, account for water depth, temperature and turbulence, even watch lure presentations - all at the push of a button.

Humminbird Basemap Built-in: Our enhanced standard basemap provides you with a clear view of underwater terrain and surrounding points of interest so you can fish and navigate with total confidence. Identify buoys, day markers, hazards, marinas, contours, depth markers and much, much more. Includes charts of more than 10,000 lakes, plus coastal coverage for the U.S.

AutoChart Live: Create real-time maps of your fishing spots, with access to patented Humminbird® LakeMaster® features. Map depth contours, bottom hardness and vegetation as you drive your boat, with eight hours of built-in recording time.

Ethernet Networking: High-speed Ethernet allows you to build a powerful, professional-grade fishing system. Easily connect multiple fish finders, or upgrade to add-on technologies like Minn Kota i-Pilot Link, 360 Imaging and CHIRP Radar.

Bluetooth: Enable features like wireless software updates from the Humminbird FishSmart App and also keep your phone out of the water and in your pocket by displaying notifications on your Humminbird. Additionally, you can take control of your most-used features with an optional Bluetooth remote (RC2).

LakeMaster Compatible: Upgrade to the unrivaled accuracy and detail of Humminbird LakeMaster maps. From easy-to-read contours, to highlighted depth ranges, to scrollable lake lists, you'll have all the tools you need to make every moment count.

Navionics Compatible: Humminbird provides even more map options thanks to additional Navionics compatibility. Available maps regions include detailed cartography for saltwater and freshwater applications which make Navionics a great option for fishing, cruising or sailing.

Includes transducer and mounting hardware, power cable, gimbal mounting bracket.

Lithium Ion batteries have a high energy density, offering savings of up to 70% in volume and weight compared to traditional lead-acid batteries. They are perfect for cyclic applications, making over 2000 cycles with very deep (80%) discharges, effectively storing 5 times as much energy over its lifespan compared to lead-acid with minimal self-discharge. Plus, they have three times the lifespan of traditional batteries.

The Mastervolt MLS series is perfect for smaller capacity applications where reducing weight/volume is key, such as on smaller vessels including dinghies and kayaks, for portable applications such as fishfinders, plotters etc, or for power back up.
They are specifically designed to be as easy as possible to install with an integrated safety switch saving installation time making them a straight-forward replacement for most existing lead-acid batteries. For higher capacity, multiple MLS batteries can easily be connected in parallel.
