I have a Jackson Nexgen.
it has solar recharge cells and 2 batteries.
cut/weld/gring mode
adjustable shade and delay.
batteries last a long time.
it has auto power off when not it in direct light after a time interval.
an inportant feature to have in an auto darkening helmet especiall for out of positing or confined areas is multiple sensors.
many only have 2 sensors.
the nexgen has a wide and tall view with 4 sensors. objects in front of your sensor will not let it auto darken.
buy a 4 sensor helmet.
jackson also has a new head gear that is very......... comfortable.
worth heading into a shop that sells them for fit.
comfort is also inportant.
i have had mine around 10 years and still works great .
