Binoculars are an essential component to any boater's navigation tool kit, I've trawled through hundreds of Prime Day deals to find you a selection of the very best deals...
Note: Prime Day 2023 has now finished, but if you’re looking for a waterproof speaker then check out our guide to the best waterproof speakers.
Everyone who uses a boat really should have a pair of binoculars in their kit inventory. Whether you’re an offshore sailor like me or a coastal hopping day sailor who likes a leisurely pace, binoculars will help you navigate accurately and for those happy moments on anchor, we can spot wildlife around us or when we head ashore we can use them for keeping an eye on our anchored boat or for more interesting things beyond the scope of the naked eye. I love watching the world through my own Steiner Pro Binoculars and there’s some deals to be found on those as well as some great models for wildlife spotting and sky watching.
Below is my pick of the best waterproof binoculars deals right now this Prime Day.
Don’t forget, if you want to get the best price, you’ll have to be an Amazon Prime member – if you aren’t already, you can sign up for a 30-day free trial.

Steiner Commander – save 23% (now £976, was £1,271.97)
These are 5-star rated by us and quite frankly are the dogs doo dahs of marine binoculars. You’ll be hard pressed to find any better than these. With hydrophobic and light filtering coated lenses, they’re easy to focus and can take virtually anything you can throw at them in terms of marine weather conditions. They’re not the lightest, but that’s absolutely fine. They are reassuringly solid. The eye cups are great for blocking stray light too. These have the built-in compass for easy pilotage and for taking bearings and readings of objects and height of distant objects.

Pentax 63620 Monocular VM 6×21 – save 38% now £112.00 was £179.99
Ok, so this is a monocular not a binocular but hang on in there for a moment… this is a brilliant deal on a brilliant bit of kit. Yes Binoculars are ace, but so are monoculars. This lightweight Pentax optic will be invaluable in quickly spotting something on the horizon or for spotting things quickly and easily. It can be stowed in a pocket and pulled out at a moments notice. By using one eye it is incredibly fast to focus. If you’re going a spot of pilotage in daylight or trying to work out what a night mark is on a ship you’re approaching, this thing is invaluable as a quick and ready tool to work out what they heck is going on just over there…
I highly recommend this as a really useful bit of kit to use alongside a longer focal/magnification binocular.
There’s 38% off. You can thank me later.
