| Can anyone give me some info on these? Are they constantly on? Are they adjustable? |

Dont know about the Trijicon red-dot, but i had a Docter sight.
Its 'always on' even in pitch black. When the cover goes on, or you are in pitch black it goes into "sleep" mode, in which the battery consumption is so low, that it will last 5 years. It doesn't have "click" adjustments, but it does come with a tool that you use with the edges of the sight body to do adjustments, IMHO its an easy as pie way to adjust it. The Docter sight is all glass, stainless steel and alluminum, so its pretty tough. I personally found it to be very bright in daylight, and good for night-time also. If anything mine was a little bit brighter than it needed to be, and seemed to flare up a little more, but if you were concentrating on the target it wasn't a big issue. It was a great sight, but it didn't have any QR low profile mounts, so I sold it to a friend for a backup sight on his Leupold scope. |

They are always on. The unit has a light sensor and auto adjust to ambient brightness. The hood does not do any sleep mode, it just sees thought the light sensor as if it were dark because the sensor cant get any light. Same output as if it were in the dark. They are fragile units. Dont think the DR Optics is tough because its metal and glass. Drop your rifle upside down from waist height on concrete and expect a destroyed optic. You really need a protective hood. I ran a Dr Optic for many months as a primary optic. It has quite a bit of distortion at the edges of the glass which is common with that type of mini dot sight.
I would not be inclined to think the Dr Optic is more durable as the metal will dent if impacted and the glass will crack if flexed. The polymer Triicon may not be as strong of a meterial but it can bounce back from an impact without breaking or denting like a Dr Optic. Both are still frgile. The Dr Optic has a bit more blue tint in the glass but less than some cheaper units I have tried. As the battery in a Dr Optic ages the sight gets dimmer. Its not as bright as an Aimpoint at 2 years and for sure it needs a new battery at about 3 years. A T1 is better in every way but price, size, weight, and auto adjusting. The T1 is tougher, more water proof, easier to sight in, has more battery life, is brighter, has a more precise dot, has less optical distortion, and less of a blue tint than the Dr Optic. The Iron Dot mounts solve the need for a hood, give a good height, and give a good QR Mount. I still think the T1 is a better optic. |
