The trouble with modern cheap binos is thay may be OK when new, but amost the slightest knock throws them ut of collimation, and they are not usually adjustable to fix this.
I have an old (pre electronics) and heaviliy used Steiner Commander and a cheapo Aldi 7x30. The Steiner wins in every aspect. Last winter I have sent it to Steiner for check and service. It came back and looked brand new. The cost was about £ 50.
I'm attempting to correct decades of calling my pair of monoculars a pair of binoculars, and call them a binocular.
Oh, I wonder if you could let me know how you got them back to Steiner etc. I have a pair that would be worth improving like that. Many thanks.
Pedancy alert.
I noticed in that website referred to by others that they refer to a binocular in the singular.
Then thought about it. Yes, that seems right.
We don't have a pair of binoculars, its a pair of monoculars. Or a binocular.
Without two eyepieces and sets of lenses, it isn't binocular it monocular.

No one else seems to value - or at least mention - the one attribute about my binoculars that I find invaluable and why I use them most. As a really ancient mariner, and in common with most ageing eyes, mine have lost their ability to adapt well to dim light so my maximum pupil size is down to around 5mm or even less. At dusk, my 7x50 binoculars suddenly reveal many objects not visible without them; buoys and channel marker posts suddenly spring into view that before, in the gloom, had been invisible.
I would really feel handicapped without a decent pair of 7x50 binoculars when closing a coast/refuge/harbour/anchorage but especially at dusk or at night.
98% of binocular use is in full daylight, so the light-gathering power is not especially important. The last time I used my ancient but good 7x50s in preference to my Canon IS 10x40s was when approaching the inadequately lit Dovetief channel just before the end of twilight, when they really came into their own. Having a pair of 7x50s on board is indispensible on the average yacht for the odd occasion, but others may well be better in daytime use.I use Canon 10x30 with image stabilisation on the boat. My concern had been that the aperture would have been too small in poor light.
Although I haven't been able to compare this to a pair of 7x50s in poor light, I have been pleased with their effectiveness in such conditions. It may be that the image stabilisation enables me to make better sense of what I am seeing, as the light that is gathered is less than the wider aperture binocular.
I do have a certain lust for image stabilisation but with two pairs of 7x50s on board (the superb ex-USN ones and very serviceable Greenkats as mentioned by another poster) find justification difficult with so many other non-essential requirements.I use Canon 10x30 with image stabilisation on the boat.

Horses for courses, I suppose, it all depends on one's sailing area. My marina lies 5nm within an Italian lagoon complex, which I also explore widely, and I often find myself feeling my way in poor light and facing a labyrinth of twisting channels marked by a confusing maze of bricola posts. On a falling tide (yes, we get a 1m difference), one can become severely embarrassed taking a wrong turn. As you so correctly note, the 7x50s are indispensable.98% of binocular use is in full daylight, so the light-gathering power is not especially important.

I'm quite happy with my plastimo fixed focus 7 x 50s which I've had since I started sailing. Variable focus types are best avoided IMH. My pal has some Steiner commanders with built in compass which are very good optically but I'd worry about them getting knocked.
