The “HUMMINBIRD XNT-9SI-180T T/M DUAL/SIDE IMAGING TRANSDUCER” which came with this unit is one of the best and is being used in new models. The Humminbird HELIX 7 SI/GPS Combo is one of the most advanced units out there and there are only two ways you can upgrade the transducer; hardware and software. To upgrade the hardware is not worth it. You might as well buy a new one which makes no sense. Fortunately, the Humminbird HELIX 7 SI/GPS Combo comes with upgradeable software and you can access software updates to enhance the performance of your Humminbird unit using the microSD Card Reader which came with the unit. The software upgradable feature of this unit ensures unparalleled performance for years to come.
