Although the total weight of the ATX is calculated at 5.5 lbs. (2.5 kgs.) and feels like it when all compacted up, I found that with the coil extended, the unit is quite ergonomic. The design of the unit actually turns it into a straight rod, shifting much of the weight from your elbow to your shoulder, a much stronger configuration of bones, muscle and tendons. Although the package included a Garrett Detector Sling, and Steve highly recommended I use it, I still haven't attached it to my ATX. I had hunted in one lake for seven hours straight in August for test purposes, and found my scoop arm much more sore. I doubt very much that I could have done it with a common "S" rod. With the coil extended the proper length for me (5" 10" and probably shrinking) the unit was nicely balanced, to the point where it would nicely float on my fingers at the proper angle for hunting. My fingers were not fatigued by having to squeeze the hand grip where the controls are located. That in itself was a bonus. My right arm, which I scoop with, tends to get carpel tunnel every year in the fall from overuse.
