Review: Not great quality for the money - This is the second monocular like this that I have bought and they both appear to have come out of the same factory so I knew what to expect. My other one was branded Celestron who make the telescopes but with a mil gauge compass (6400 "degrees" instead of 360) which I hadn't expected when I purchased and wanted a standard compass bearing measurement so I opted for this one even though I knew it was likely of the same quality. The price of this has varied over the last few months - ranging from over £100 (£120 or so I seem to remember) down to the price I eventually paid at just over £65 and I have to say for the quality even this is really too expensive due to a couple of reasons that I will go in to in a minute. Really I have had better binoculars (admittedly without the compass) for less than half this price. I definitely wouldn't have paid the higher price they have been on for. So now on to the problems. Firstly - the lens, This is nothing special, even when you dial the focus in sharp but it is OK. The issue comes with the act of focussing the lens for viewing an object. Depending on distance, you can end up with an object in focus which results in the reticle and compass going completely blurry. Once you adjust the focus for the reticle and compass, the subject is blurry. The design of how the reticle and compass work in conjunction with the focus for distance is really not good. The second issue is the compass itself. It is readable enough and doesn't need tonnes of light although needs to be reasonable, but this can be compensated by injecting some artificial light through the aid of a torch if need be. The main issue is it sticks, it sticks quite badly and does so a lot - I certainly don't think you would want to rely on it as your main navigation aid. My view is this is for a guide only or for confirming what you think a bearing should be but not really recommended if your life depended on it! I would like to go on to add that I do not believe this to just be a faulty unit. Both these issues are identical to the equivalent functions on my Celestron version - they really do look like they come out of the same factory with a similar pouch and box just with different options on the reticle and body colour. I do like the idea of having the inbuilt compass and I have a really high quality pair of binoculars (Bynolyt SeaRanger II - that are absolutely brilliant - same brand I believe has been used by RNLI ) that have this function - but as I only really have one effective eye due to bad eyesight in the other, and the fact I wanted to have something small and convenient for use on a RHIB for scuba diving and spotting, I was willing to pick this up as a backup - even though I knew the likely faults before I purchased. I do wish there was a better quality version - but I begrudgingly stumped for this over-priced not great quality one because I haven't seen anything else around in a monocular that doesn't seem to be made to a higher quality design. Review: Compass very poor - Compass very poor and though they claim this on their literature received with the product, it is never mentioned in the sales literature ## Features - Nautical Observation: The monocular is waterproof and designed to specifically for the nautical and boating enthusiast. - Precision Optics: With high quality BAK-4 porro optics, the binoculars brings you exceptional clear views to enjoy from sunrise to sunset. - Rugged Design: The binoculars is dry nitrogen-pruged and sealed.

Lots of information online. Just look up Mil-Dot or Mil-Dot rangefinding the user's guide from mil.dot.com has the basic info. other pages on their site have more : http://www.mil-dot.com/user-guide Wikipedia also has lots of bakground: https://en.wikipedia.org/wiki/Milliradian FWIW, I use my barska sight for coastal navigation along the gulf coast where it is important to keep minimumm distance AWAY from various landmarks because the Gulf is so shallow. This scope with its built in compass is my number one navigation tool. **Q: What is the eyeview comfort time on this?** A: In general I never keep it in My eye for any extended period of time, but I have to say that I've noticed no discomfort in the times that I have used it it certainly has good resolution and I wouldn't hesitate to buy it again. It turned out to be a little bit larger than I had anticipated as I was looking for a small pocket monocular, But that's made up for in its clarity and range of vision. In general I think you'll like it Jane, good luck **Q: Is the eyepiece rubber or does it have an eyeglass spin function?** A: I forget I didn t like it and returned it. wasn t much clearer than a cheaper one I was gona replace with it. ## Customer Reviews ### ⭐⭐⭐ Not great quality for the money *by E***R on 26 September 2024* This is the second monocular like this that I have bought and they both appear to have come out of the same factory so I knew what to expect.
