For fishing, I generally use Pentax UP 8 x 25 WP. Very compact, superb build quality, waterproof, very clear images... just brilliant to tuck into the rucksack.
I do also have Pentax ZD 10 x 50 - only use those when session fishing, as they're heavy and a bit bulky, but being top-end optics, just awesome at whey they do.
You can't go wrong with Pentax Binos, even the cheaper ones are really good.

I have a pair of top quality Russian Zenith 7 x 50 binoculars with yellow and green clip on filters these are just AMAZING !! you can see perfectly when its almost dark trouble is they are bloody huge !!
you divide the magnification with the end lens size the higher the number the brighter the image in this case 50 divided by 7 =7 thats called the exit pupil diameter
its the amount of light reaching the eye but this would go down if you increased the magnification so a 10 x 50 wont be as bright as the exit pupil diameter would be 5 not 7 quite a drop !!
having said all this a good quality 8 x 25 will be brighter than an 8 x 42 if the 42 end lens was a poor quantity lens

Possibly worth pointing out that as you age the maximum pupil size for most people will reduce. By the time you get to your 70s it could well be a lot less than 7mm making those 7x50s just as bright as 8x40s for your eyes.

Funny thing is I have always had good night. vision I mostly hate lights at night
in my home I get up a couple of times a night for a pee I never find the need to turn a light on even though its pitch black I can see perfectly when I go fishing I can walk round the banks without using a light hate it when someone comes round with a head torch on I always ask them to turn it off it takes about 30 seconds then I can see again properly
its quite amazing just how well we can see in the dark
try this easy test when you go to bed turn the light out then look around the room straight away you wont be able to see much at all now close your eyes count slowly to 40 then open your eyes and you will be amazed how much you can now see
