I've found the GPZ 7000 to be a dream to use,I dont use the harness, but the best practice is to use the 7000 close to you, You only need to sweep 25 to 30cm each side of your feet, keep your arm straight, your motion should be almost effortless.
We can do 12 hour days, but 2 12 hour days and the 3rd day we'd only do 6 or so.
My mate has a 5000 and when I follow him, I pick up gold he misses, when he follows me, he picks up gold I've missed,and 2300 following behind us lets out a whoop more often than I prefer to hear
