here's another tip that'll help you get started with your humminbird helix picking a suitable mounting location for your humminbird helix is important for optimal performance first make sure you have enough length in both your transducer and power cables to reach your desired location then think about how you're going to route those cables to the unit keeping power and transducer cables physically separated to the extent possible will help to minimize any electrical interference finally ensure that your helix has an unobstructed view of the sky your helix has a sensitive internal gps receiver located on top of the unit but this receiver will have a hard time listening through solid objects so avoid mounting your helix in a compartment or next to a tall gunnel that might obstruct its view of the sky
