Depth is supposed to be comparable to the White's PI (Pro) if assembled properly.
All depends on your search coil build as well. My White's PI Pro has no problem getting a nickle at 12" at our local beach if that helps you. That's why I chose this PI as a project build, not to hard and you can experiment with several coil design and materials. A platform to learn on.....
As for tuning, basically it's two knobs Sensitivity and Threshold for actual hunting. And if you want the external delay. Follow instructions for the White's PI models and Dual Field for control settings. Takes me about 1 minute to set up my PI for beach hunting.
So take the plunge, build your own detector. The satisfaction you get building your first hand built working machine is second to none. Don't worry about depth capability on your first build, there is plenty of room to experiment. Who knows what your build may lead to.........I used to design and build radio control boats, your always redesigning and building new faster sleeker versions. Always had two on the building board and another design developing in my head...talk about a hurting brain. Once on a build role, you can't stop, there's always one more to build. Since moving into a much smaller living quarters had to give up my boat building work shop. Building a detector for me fills that void, can do it in a smaller area.

So worry not about depth, just hope it turns on when power is applied.
