Added weight is not a bad thing in the right location, as in the rear of the detector, helps the balance. I find better the balance better the swing, takes less wrist strain and put the weight on the whole arm which I can handle better. I added a whole pound of fishing pencil weight to the end and it was a whole lot better than stock weight. What would be better is if someone could make a battery container that took a bigger battery than what comes with the machine and attached to the end of the shaft. Delete the internal battery in the handle, run the wires though the shaft. More battery capacity and moves the weight for better balance. May not be water proof anymore, but I don't plan on going in the water anyway.
