Hi, Help please. Trying to work out which sounder and transducers I should get. I'm looking at two 9 inch screens. Was initially going a garmin and hummingbird but can't get a MinnKota but can get a Motor guide so looking at changing the humming birs over to either a lowrance or simrad for compatibility. I'm leaning more toward simrad but I'm not sold. Need to get a few questions answered to decide. Sorry fairly new to this so may be asking stupid questions. 1. Does simrad GO9 XSE support 3D structure scan and livescope? Or is this only available with NSS EVO 3s? 2. Is there any difference significant difference between lowarnce HDS LIVE 9" and NSS EVO 3s 9"? 3. Both simrad and lowarnce seem to use the 3 in 1 transducer. To get 3D structure scan and livesight/livescope require extra transducers? Is it possible to gte one transducer that does it all? 4. Does forward scan also require an extra transducer and can this be placed at the transom? Many thanks, Phil.
