SMD Q series are okay except for the touch screens (and lack of alternative switching – if you’re capable of doing 2 or 3 things at one time!), as well as those cursed Curvetech J-boxes made out of 3 different materials. Have done verticla surveys at 1.1 km/hour and they can work in max. currents thrown at it.
I believe the JB’s are now all aluminum with the perspex cover.
