2D, down imaging, side scan, GPS and live mapping capability. 7” display. Reliable and update capability.It takes hours just to figure out what it can do and to tweak it to satisfaction. Can practice using all capabilities in simulation mode. Love it.

I bought this unit to replace a Lowrance with similar features. After the second transducer failure in two years on the Lowrance I decided to try The Humminbird Helix. I immediately noticed the graphics were clearer and the printed numbers were larger and easier to read. Initial setup was a simple process and largely intuitive. The GPS and mapping work great. The transducer was more robust and much less vulnerable to damage than the Lowrance product. The only negative is the plastic, break away transducer mount. The idea is good, to have the transducer swing up when it meets an obstruction. However at speed, particularly in shallow river water the mount breaks loose under water pressure and dangles from the electrical cord. There is a stainless steel mounting bracket available which Ilan to install. At this point I am very pleased with the performance of this instrument.

Even though I am still learning everything this Humminbird will do, I can't wait to get on the water every day that I have time to go out.

Only received the head unit without any accessories. No power cable to test unit or transducer. Packaging was loose with minimal amount of protection during shipping.
