Hello everybody, first time posting here. I was wondering if there is any way to make a external receiver for a Trimble EZ-Guide 500 to get better accuracy. I am not interested in building my own GPS and my dad who uses the GPS really likes the 500. I see a guy by the name of Tynell Dake
aka user PotatoFarmer was working on a TSIP converter but it sounds like it got sold to Agra-GPS. Does anybody know if there ever going to release it for sale? Or is there any way to make something like this? Thank You.
