Even with a camera and usually with a backup helper I am always very cautious when backing up. The backup camera offers no depth perception and my helper might not be looking at everything.. focus on something and not see the tree on the other side?
Today I ran across a backup sensor system that seems interesting. I will point out it does have limits that could cause some of us issues;
#1 you must mount it 4' or lower to the ground
#2 limitation of 30' -- This is the limit (10 meters) for class 2 Bluetooth. Class 1 is 100 meters.
At any rate, I toss this out to those of you that have a shorter coach and or willing to experiment with this + Bluetooth range extender. Sounds interesting to me;
