Everybody tends to dwell on the negative, but never the positive experiences. I just want to relate my EXTREMELY positive experience with BBG Marine. I recently switched my 21PHX Phoenix over from Lowrance HDS to Humminbird Helix. When dealing with Brian @ BBG Marine, I have been overwhelmed by the knowledge he has provided in completing the project. The shipping time has been immediate ... Unbelievable! Even worked well & easily on return of defective item. Awesome is all I can say. Please support this company, or at least give them the opportunity to earn your business. Brian, you are the best! New boat has two Helix 12" MEGA SI & one 10" MEGA SI units ... can't wait to get on the water!
