Teccy Problems!

Lovely weekend spent with Nicky. Too much food but very nice. Early start this morning. Got to Taunton for 7:30am and was on the M5 by 10am protected by a crash cushion. Then the problems started. The Topcon GRS-1 suddenly froze during mid survey. Following a reset I discovered the data layer was corrupt. Tried to rescue this but failed so returned to the depot. Reloaded the data and off we went again. Met up with the crash cushion and tried again. Exactly them same thing happened so we had no choice but to abandon the survey for the day. Did some testing back at the depot and all worked fine. So annoying. Will try again and see what happens. Fun and games!
