I had the Safari out today and found the sensitivity is key I was getting high tones on nails but things got better when I turned it way down, and I was just hunting under power lines in my yard and had to go to 5 before I started locking in on targets, I think the noise cancel is important but will not matter if the sens is not adjusted for the area and that changed dramatically from back yard to front, compared to the MXT this thing is really complicated!!! but I think will be better once I figure it out.
