I bought my Helix 9 & 7 SI units from BBG. Brian is good people. Do yourself a favor and take advantage of the Humminbird transducer upgrade program. If your unit comes standard with the compact SI transducer, upgrade to the HDSI transducer. It will give you 800 MHz SI frequency for a much higher level of definition. The upgrade will cost you $85, but the transducer is $150 if you were to buy it.
