Hello new to forum. Have a question regarding striker 9sv plus unit. I have read plenty of the transducer issue. As far new vs older with apparent TRUE down image. I will be using this unit along side another unit. I will be using the striker sv for side imaging only. My question is can I turn off the gps function all together on this unit? I have another unit that will be used for gps. Thanks for any input. ALSO any opinions on the stock transducer for strictly side imaging? It seems the complaints come from the down imaging on the stock transducer. Thanks.
