🧭 Optimize Your Fieldwork with the Harbin Geological Compass DQL-8: A Reliable and Efficient Tool Review

I bought this compass to use for my studies and work and saw the brand price and knew why not. I'm glad I did. This compass is almost the same as the Brunton compass issued for the class. I've used both side by side and can't tell any difference in the readings. The quality is almost the same. The linear aiming lever is slightly bent less than a few degrees and could be straightened. Another quirk is that the inclinometer seems to be a bit more difficult to line up perfectly, but it seems to…

Not everyone can afford a $300-$500 vehicle compass. This compass has declination adjustments, a good circular bubble and a horizontal bubble for degrees and for use with an inclinometer. The compass comes with a small thread that can be used with a plumb bob or a route drawn on a topographical map. The main lens is made of glass and the body is made of metal with brass inserts for the needle damping piston. The long centering piece for the north is attached with screws and a metal flange. The…

This item would make a good display for your bookshelf. However, if you use it in the field, here are some things to keep in mind. The rear sight is overstressed, which can lead to the destruction of the glass and/or mirror. The mirror appears to be plastic. It is VERY easy to scratch, for example with a fingernail or a callus on the fingers. The main azimuth points are covered by some kind of hole in them. On the plus side, the case, hinges, and other hardware seem adequate. The compass needle

Have you ever held something in your hands and wondered how much it costs, assuming it's really expensive, just to find it affordable? This compass is one such product. This is a very very high quality inspired replica/clone of the Brunton transit except I strongly suspect this thing will outlive the Brunton (especially the polygonal models) - why? It's solid and well built and the fit and finish aren't great - they're PERFECT, the fact is this little Harbin could very well be the better of the

Overall the product looks good. No visible plastic on the unit itself, just a separate nylon and faux leather case (it even comes with a lanyard for use as a plumb line). I like the glow in the dark dots on the 4 cardinal points and the north arrow on the arrow. The inclination adjustment is stepless. The inclinometer works well. Unfortunately, the compass needle is not quite centered on my pattern, e.g. B. if you see in the photo that the red end point points to 175 and the white end point to…

I'm a geologist and I have a Brunton International Pocket Transit (Cost me almost $500). Brunton is the standard by which other geological compasses are measured. But I wanted to test out cheaper compasses for use in the geology classes I teach. The Harbin Compass is a very good Brunton copy for about a tenth the price. I tested it on the basic steps (declination, bump and fall adjustment, bearing, etc.) and was suitably impressed. It works and feels very similar to my Brunton. It has a solid…

I tried the plastic version of this type of compass but it just didn't hold up - the hinges broke - and wasn't very accurate. However, the DQL-8 is solidly built and accurate enough to determine magnetic north and read angles and directions. I adjusted the magnetic variation for my location which I got from a website and compared it to the North Star position (horizontally using a plumb bob) and it showed 0° as accurately as I could read it. The porthole elevation is fairly sensitive and…

I have a Brunton but I'm teaching field geology this fall and found our collection of real Bruntons in a sorry state. A search of the internet turned up a Harbin compass and I bought it on a whim to see if it would even fit the needs of our class. I confess that my expectations were not high. Of course it's about nothing. But surprisingly, the instrument itself is really solid and beautiful. It has a metal body (painted black), freewheel, weighted stylus, azimuth dial with inclinometer, aiming…

I have two Brunton Pocket Transits. My first is a plastic Com Pro 5008 and my second is a Brunton with an aluminum body from the 1950's. I used them to explore caves. They are no longer used by cavers, but in some situations they work better as tools like the Sunnto. I bought this mainly because it intrigued me and wanted to see how it compares to my other Brunton compasses. I'm really surprised how good it is considering how much it costs (55.00). I made several azimuth measurements. with him…
