I just picked up a pair of new Gen1 Helix's (9 SI at the bow and a 10 SI at the console) and was wondering what my best option for transducers are. I have heard of people "upgrading" the factory ones and was wondering if it is worth while before i get them installed.The bow mount unit is planned to be mounted on my Terrova. Also looking for info as to what people use for mounts/gaurds on the trolling motor as well. I am sure this has been discussed on here before but i could not find it on my searches.
