Lutron model PH-212, Digital Soil pH Meter (about $200) The downside with the above real pH meters is that their electrodes are fragile and the electrodes have to be replaced every few years at big bucks (at 1/3 to 1/2 the cost of the meter) and they require calibration and electrode storage solutions (if the electrodes dry out, they die), but it's still infinitely better than using gardening dowsing rods.
