For the declination adjustment there is a clear plastic disk on bottom of the round portion of the compass which has a red house like outline. This has small teeth around the outside of the disk. You adjust the declination by pressing on the disk from the bottom and moving it a few clicks as needed. Then you move the bottom disk a few clicks until it aligns to the declination that you calculated for your location. Now you have the degrees on the ring aligned with true north instead of magnetic north. It works fine and seems to stay set with gentle handling, but there is no set screw to hold the declination adjustment. While using the front sight it is also necessary to align the image in the mirror to have the center pivot point of the needle directly under the vertical slot in the mirror. If this is not aligned, then move your head slightly left or right until the needle pivot point is under the mirror slot while keeping the red side of the needle inside of the red outline. This helps improve the accuracy since there is no rear sight when looking through the hole under the mirror. For night time use there is a glowing dot on the center and north of the needle, on the front sight, above the top of the mirror, and a large arrow on the base plate. They glow fine and work to get a general sense of direction, but there is no glowing on the red outline. At night time you need a flashlight to put the RED side of the needle into the red outline which does not glow. There is a triangular clear piece with an arrow which sits on the bottom and pivots around the center of the needle base. If you turn the ring until E (east) is pointing to the rear sight at the bottom of the hole below the mirror, you can then lay the top mirror lid completely open and flat with the base plate, then tilt the compass until the left side is straight down with the right side straight up (compass on its left side), shake the compass slightly to get the triangular piece moving freely, and it works as a clinometer while sighting a mountain peak along the right edge of the compass. The clear base plate works well on maps and has several scales. Overall I give it good marks especially for the price.

So many great features on this compass and well worth the price! I compared this with a Brunton Truarc 3 and the accuracy is the same. I see why some people are worried about the declination changing once set (but this is such a minor issue considering what you are paying). Other than that this is a really well built and solid compass and strong glow.This offers the same features (and more) to the Silva Ranger 2.0 but at a fraction of the price, great for someone who may not need to use it much but wants all the features.

This is almost as good as my expensive Silva. I wanted an inexpensive compass to keep in my raft, where I need it to help in campsite selection (where will the sun go down?). It seems well-made and easy to read. I never use a compass at night (at least not intentionally) so I will likely never know how well the fluorescence works. The simple, but effective clinometer is a plus. A minor complaint (thus the 4 star rating) is that the declination adjustment is a clear plastic sheet located below the compass case. It is adjusted by holding the case in place and spinning the sheet. Unfortunately, it is fairly loose and I had to tape it in place. Declination here in Oregon varies from 15 to 20 degrees -- so it is important to get it right.

What a. Piece of garbage!All a compass has to do is point north. This does not only about 18 degrees offTried returning it but Amazon is just sending me another one which I don’t wantIt’s just cheaper to get the replacement and that’s what amazon is hoping for couple dollars here there whatever

They are a bit sensitive to metal, so know if you're wearing a wrist watch they work more accurately if it's taken off.Used for a maps and orientation class and they were perfect.

This compass can be hacked to work pretty well, but I don't recommend letting your safety depend on the hacks!The basic problem is that, as reported by many here, the bezel and declination disk do NOT retain settings. Just a light touch is enough to send either way off. Not good for much of any land navigation.The pictures show a hack, using 1/32" "Speedy Sticher" waxed twine to dampen both defective parts.Obviously the twine COULD come out of either place TOO easily. But if it is put in snugly, the compass is VERY useful. Tying the longer section into the groove between the white bezel ring and the baseplate is the biggest challenge. Shoving the shorter section under the declination plate is the lesser challenge.It's a real shame these hacks are needed. This compass works VERY nicely, once those are in place. The inclinometer is remarkably accurate. The declination adjustment markings seem right on the money. Bearing readings match those on some far more expensive compasses in my collection. The sighting mechanism is my favorite among the mirror compasses I have tried.I am OK with this, hacked, a couple miles off the beaten track. I would NOT be OK with this if I were HOURS off the beaten track. To get the same features, though, in a compass I WOULD trust I'd have to spend closer to $100 for a K&R Alpin. The K&R Sherpa looks even more like this TurnOnSport, but lacks the inclinometer. Suunto is less than $100, but ruins half the bezel area with a mis-placed logo. The Silva Ranger always seems to be inbetween suppliers, so it's hard to know WHICH Ranger is actually available.Without the hack, the TurnOnSport compass rates less than 1 star. As others have noted, it is DANGEROUS for extended backcountry navigating. For now, I am rating it 3 stars WITH the hack ONLY. And still refraining from depending on it too much!Such a shame, as it has a GREAT feature set. Brass (or even plastic) springs between the capsule and delination plate, and basebplate and bezel, would bring this up to a 5 star compass!

It’s great for the basic experience. Only issue is crack of the housing. To my mind it’s transportation fault. So I got refund after my report.

It is relatively well made, except for the declination adjustment that is a bit wobbly. That is what you get for the money.

Delivered with hinge pin half way out, hinge pin not very secure

The magnetic north offset does not lock very well and when pressed to lock, it can come apart.

Cheap cheap cheap!!! Don’t buy this!!!!
