Need to replace the the Garmin hockey puck (18x LVC) on a old Case AFS yield monitor. Need serial connection. I can get the same unit for under $100 but wondering if there is something better out there for under $300? Looking for something with better accuracy for not too much money. The Garmin is < 3 meters. Found this unit but have no experience with it. https://www.navtechgps.com/assets/1/7/TW5340-TW5341_DS.pdf
