The difference between the two is the LR50W is wireless compared to the LR50. 

Can I use a remote display?
Yes, the LR50W can be paired with Spectra Precision’s RD20 In-Cab Wireless Remote Display. This makes the operators job easier and more efficient by seeing the grade in their cabin. Note, only the wireless model (LR50W) will work with remote display!
