I bought the TDR 100 from Spectrum Technologies. It works for me, being that it stores easily and I can lock it in my cart toolbox. I might buy the 300 and give my assistant this one. Each works basically the same, one just has more options available for it. I've been experimenting with my "number", but thanks to this fine Midwestern summer, I've become more attuned to keeping the course alive with my "irrigation" system.
I do use it for the hand watering crew, basically to check if enough water has been applied. I was amazed initially how low you can go and skip watering.
I don't rely on it for most of my watering decisions, but to confirm my thoughts on way or the other.
Best of Luck.
