Handheld units are useful for checking spots, but I rely on Turfguard sensors to track my watering schedule. In severe drought and high ET rates. They do the best for tracking the moisture over several days, weeks, months and even years. Not to mention temperature and salinity if you have to worry about those things. You should try a two or three at first. We have them on Fairways, Tees and Greens. If you are putting them on the greens, install them on the slopes or were someone will not hit them with a cup cutter.
