It takes a while to line up all the marks,as they are small,but this is an excellent unit.I used it along side a friends GPS unit,and it turns out that the compass was faster oan more accurate than the GPS.There is alot to be said for "old school methods"!Thanks
Pros: Extremely accurate,durable aluminum case
Cons: Diel markings are very small,even through sighting bubble
