You want an optical instrument that can help you get a closer view of the beach. Apart from binoculars, what ground standing gear can you use? You won’t be limited by choices, that is for sure, but what’s a good scope to have have in the home?
Spotting scopes or Refractors are great options. There are small differences between them but both are designed with a objective lenses so images are projected the right way up. Remember reflector telescopes? Their mirror design produces vertically inverted images. You won’t have that problem with spotting scopes or refractors however.
Spotting scopes usually have a shorter tube for the same focal distance on a refractor scope. They are also usually designed with a zoom feature so you can vary viewing distances from 15x to 35x, for example. Refractors are often fixed in their focal length, and you might use eyepieces to vary your power (standard telescope eyepieces are 1.25”).
Refractors, most of the time, are used for casual astronomical viewing. They are still built with a telescope mount and angled for viewing on the night sky. Some may find it less comfortable for use on land. Spotting scopes will use any universal camera tripod, although a heavy duty tripod is recommended.
