We have been a bit quiet on Facebook at Rylands due to the amount of work we have had to get through over the autumn/winter period. Still very busy though!! We thought it was about time we upgraded our old TrimbleT41 for tree surveying. This is our new Trimble TDC600 an all singing and dancing model for the next few years. Technology moves on so fast and within 5 years our TrimbleT41 was outdated. We look forward to using our new hand held computer, on a new survey of nearly a thousand trees. Happy surveying February!!
