Hi, I work for a company that is looking to replace our CS10, now that the 3G has been turned off. \n\nWe don't have much of a budget, so anything under £10,000 is preferred. We're looking at refurbished equipment.\n\nMy main question is this, what system would be good to buy that will work for the next 10 years on 4G? it can be Trimble or Leica or whatever. We only use GPS for co ordinates and levels, so it doesn't have to be top of the line. \n\nAlso, I've come across a brand called Emlid Reach and another one which just says G7 GNSS, they are both significantly cheaper than others, is there a reason for that?\n\nThank you in advance.
