The range isn't the best, being all digital. Also, you are supposed to be able to navigate straight to a victim, but I noticed a tendency for it to follow the flux lines. Further, when you have it strapped on the way it's designed, you can't get the unit close to the ground while standing for precise locating. It's got a cable that keeps it within a couple feet of you chest. Might have to cut the cord. Finally, the multiple victim feature is a bit confusing, it jumps around to different numbers rather wildly.
