I bought this compass as a backup, (wrongly) assuming it would be a compass capable of taking bearings/azimuths. Unfortunately, it is not very well made and neither liquid-filled nor dampened. As a result, it is very inaccurate and unable to consistently give a bearing - repeated attempts can be out by as much as 10 degrees.
The needle housing turns well, but the needle binds too easily to the inside of the housing, meaning each bearing reading requires a fair bit of time to let the needle settle. To add to my concerns, the needle also appears to be weakly magnetised, meaning bearings are inconsistent.
Overall, this would probably have been a good compass in the 1950's but it's simply not good enough given you can today buy an excellent, semiprofessional compass from Silva or Suunto for less than £10 and a toy "button" or "key ring" compass as accurate as this Gelert for about £2.00
