Hawaii,
The Beltronics is very good but not the best. you can not get true 360 on a bike. I use the 946i because;
Battery operated
Headphone instead of crazy speakers
laser & ka, K & x
Velcros on the top of the tree
Sees most but not all
make sure you change batteries when you get a warning
Buy 2or3 headsets when you buy the unit, the wires twist in the wind.
