I'm comparing portable drone detection devices and have realized that the advertised detection range isn't the only specification worth considering. Battery life, weight, supported frequency bands, and the way alerts are presented seem just as important, particularly if someone needs to carry the equipment for several hours. I'm also interested in how easily a user can interpret a detection instead of having to figure everything out from a technical signal indicator. For those with experience in this field, which features would you put at the top of your comparison list?
