Trying to decide on new fish finder for kayak. My choices I'm looking at are:
1) Humminbird Helix 12 HW CHIRP Mega SI GPS G2N
2) Humminbird Helix 9 CHIRP MEGA SI+ GPS G3N
3) Garmin ECHOMAP™ UHD 93sv with GT54UHD-TM Transducer
I really want the SI and DI capabilities. I'm throwing the Garmin in because it is livescope compatible if I ever decide to go that route. I'm worried about the 12 being to large for the kayak. Be like trying to cast over a large screen tv when sitting inside a kayak. Any help would be appreciated. Thanks
