I love my two Toro sprayers with Geolink but to be honest, I would have never gotten them for the reasons that sales people were pushing. They said it would save money in applied product. These machines are expensive and I wasn't seeing any return on a 10-15% savings due to less overlap and waste because the fertilizer I spray is so inexpensive and we hardly spray any fungicide or other expensive chemicals. There is definitely less overlap and waste. Zero overlap actually. With traditional sprayers I was taught to mix 15% extra for overlap and overspray. With a GPS sprayer, you actually spray slightly less than the designated area. It only overlaps if something goes wrong. They also said it would save time because there was less overlap. For me it doesn't save time because autosteer only works below 10 km/h and I used to like to let'er rip and spray at 12 km/h. We have 18ha of fairways (44 acres) and very limited weather windows so you have to go fast to stay ahead of golf ...
