The calibrated hinge type is much faster to use though. It really depends on the level of precision that you need for the work you are doing. I think for a lifetime purchase, a Brunton is a fantastic deal.Christie Rowehttps://www.blogger.com/profile/17131186132737346311noreply@blogger.comtag:blogger.com,1999:blog-5950727852821572506.post-52514578294996743052013-06-21T22:34:44.313-04:002013-06-21T22:34:44.313-04:00I use a Breithaupt Stratum transit-- it's a be...I use a Breithaupt Stratum transit-- it's a better designed and built version of the Brunton Geo. for roughly the same price. But I'm also a structural geologist who takes about 3-4000 measurements a year during production mapping, so it's worth it to have something well made that works for me.Joe Koperanoreply@blogger.comtag:blogger.com,1999:blog-5950727852821572506.post-83329625120436532632013-06-18T08:28:39.777-04:002013-06-18T08:28:39.777-04:00I own a Brunton, and have since my my undergrad da...I own a Brunton, and have since my my undergrad days (thanks to my mom and step-dad!!!!), but having done work in Australia I must say that I would FAR rather have the sort of structural compass they use there, since they are MUCH easier to use. Instead of measuring strike and dip desperately one sets the bottom of the compass on the outcrop and both adjusts the hinge of the compass such that the hinge line is parallel with the strike and the compass body is parallel with the dip. One then reads the dip direction (instead of strike) off of the compass face and then picks up the compass and looks at the markings on the hinge to read off the dip. <br /><br />This means that one can measure dip in places where it would be hard to get one's head to look at the clinometer of a Brunton, since the instrument remembers the dip until you move the hinge.<br /><br />Sadly, I don't recall the name of this sort of compass, but the last time I looked them up they were way more expensive than a Brunton, and I couldn't afford it. Now that I might be able to afford one I am not doing any field work, so I haven't bought one, yet...A Life Long Scholarhttps://www.blogger.com/profile/13930670217574191380noreply@blogger.comtag:blogger.com,1999:blog-5950727852821572506.post-5693003330370280962013-06-17T19:43:48.329-04:002013-06-17T19:43:48.329-04:00I just bought two Bruntons with my first research ...I just bought two Bruntons with my first research grant.

The compass app also displays true north vs. magnetic north.Rock Headhttps://www.blogger.com/profile/05543769768515349524noreply@blogger.comtag:blogger.com,1999:blog-5950727852821572506.post-78688824898198752272013-06-15T11:48:56.413-04:002013-06-15T11:48:56.413-04:00Well, if lack of a Brunton diminishes one's cr...Well, if lack of a Brunton diminishes one's credibility as a geologist, then mine's completely shot. The last time I had my hands on a Brunton was in the late 70s in university (about the same time I last used a plane table and alidade). My 30+ years career since then has all involved cuttings and core, for which a Brunton has limited utility. I've done a bit of hobby mapping and for that my old Silva Ranger is "good enough".<br /><br />--HowardAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5950727852821572506.post-5633283564960645202013-06-15T07:55:25.525-04:002013-06-15T07:55:25.525-04:00I still use a Brunton, my second version so far (d...I still use a Brunton, my second version so far (don't remember what happened to the first one, which I was required to buy for field camp), and will someday (soon?) upgrade to an azimuth version, because mine is still old fashioned enough to use N xx W and N xx E, etc.<br /><br />I use it for any mapping I do, and have used it for claim staking.Silver Foxhttps://www.blogger.com/profile/03131032620978696727noreply@blogger.comtag:blogger.com,1999:blog-5950727852821572506.post-21451578800403086932013-06-14T01:38:43.121-04:002013-06-14T01:38:43.121-04:00Never trust a geologist who doesn't have a bru...Never trust a geologist who doesn't have a brunton. <br />No, I'm totally kidding, those fuckers are expensive. <br />My old structural/sedstrat prof epoxied little level bubbles onto regular compasses, and attatched a mirror and some other shit.
