These are nice user friendly systems, with automatic modes, as well as advanced. They have long range, and good wall radio penetration. batteries are all up to snuff, and the AC/dc charger is more dependable then the ones that have them built into the case. I would have no qualms having to use this today. This also includes a rare ground microphone that allows for 12 levels of comparison.
Full system filtering, and velocity calculating capabilities as well.
