I picked up a couple trimble MS750 recievers. No cables or antennas. I didn't know what model they were at the time of purchase. I thought I might have a chance of getting waas on them. I guess they are just RTK. All I do is soil testing across midwest. RTK is too expensive and just overkill for me. I was just wondering what they are worth in working condition? I see some selling for about 800-1000 on ebay. No idea if those are actually selling though.
