Also very interested in this thread.
Will be upgrading my sounder soon, and want to get one with downscan and custom maps. Not too fussed with sidescan itself, but 3D maps would be great. From what I have researched, Lowrance/Simrad seem to be the only ones with live 3D Mapping?
After creating 3D Maps on ReefMaster, can these maps be displayed on the sounder? Couldn't find too much information/videos on how well ReefMaster 3D maps are transferred across to a sounder and how it looks. Or much on bathymetric maps, compared to Lowrance/Humminbird etc.
I fish from a kayak offshore, usually not any deeper than 40m. Is the Hook2 just not powerful enough for that depth? How does the Humminbird Helix G2 stack up against Lowrance Hook2, or Lowrance Elite Ti? What would you recommend for my case, and use with ReefMaster?
