I bought this to replace a basic Tasco unit that got lost during the last move. I was happy with the little tasco as I was using it as a lightweight alternative to binoculars for hiking and quick spotting. Compared to my old tasco, this unit is a monster, which comes with mostly good and a little bad.
The bad obviously is its physical size. In its case it's roughly 3"x3"x6" which is not subtle on a belt or backpack strap. As for the weight, while noticeably heavier than my previous unit, I don't find it to be excessive, and actually found that it felt lighter than I expected, without feeling cheap. Speaking of cheap, the lanyard that comes with the unit is a little flimsy, and the fact that it's what holds the viewing objective cover on is a little anoying, as it has a tendancy, as another review pointed out, to tug at the cap, and sometimes dislodge it. Also, there is a slotted piece that protrudes slightly that looks like it was for a hand strap, which would have been nice, but was likely scrapped in production to cut costs. The case itself is nothing special, soft lightly padded nylon that functions mostly as a holder rather than a method of protection, which is about what I expected in this price range.
The other side of this coin is that because of the large objective lens, low light and night time viewing are substantially better on this model. Additionally the viewing angle is much larger which makes it easier to find and track objects. Furthermore, I didn't notice any significant distortion at the edges, something I was aware of on the tasco.
As for the range finding reticule, I could take it or leave it. I don't find that it interferes with my view, but I also haven't really used it other than for the novelty of it. I do like the compass, and while I would always carry a proper compass with me on a trip, it's nice to be able to determine the direction quickly while enjoying the view. Another buyer indicated that they didn't like that the compass took up the bottom 25-30% of the view, but had I not read that review, I wouldn't have even processed that I was "losing" a portion of the image. Even with that loss, the viewing area is still much larger than what I was used to.
Lastly it is water and fog proof. Thankfully, I can't speak to the effectiveness of this, but others have said it's solid, and it was a selling point for me since my typical luck with weather isn't as good.
In sum, if the bulk isn't an issue, this is great unit, well built, versatile and easy to use and it will provide a great image. If the size is an issue, then you need to decide if you want to spend a lot more money or sacrifice on the image quality and versatility.
