How slow can you move the coil?

I like to search really slow, but I seem to lose depth. How slow can you move the coil in the all metal mode and still get good depth?.....Coach

If it is a MOTION a/m mode, you have to experiment with different sweep speeds to find the best rate. If it is non-motion you should be able to move it as slow as you want and retain the same depth.

Yeah with non-motion you can hover motionless over the target and lose nothing. If it's motion then it has to be moved slightly to maintain a signal but the slower you move it the less depth you get. The faster you move it the better it discriminates and the deeper it goes.

If you are in motion discriminate, there has to be some movement. On shallow targets, you can get down to a few inches per second in sweep speed. But in general, you need to maintain a pace as recommended by the manufacturer.
On multi-filter designs liekt he Garretts, A somewhat faster than normal speed will get you MORE depth.
In fact, if you get a short-audio hit that indicates deep, whipping the coil over the item will tend to firm up it's responses.

I know I'm not an expert, but I would recommend to place 2 targets on the ground, a good and bad one, and try passing the detector over the bad one (rusty nail or similar) before the good one, so you can determine the recovery speed of your detector. Then stick to that speed so you don't loose some precious targets. Just my 2 cents.

Good luck and happy hunting!
