As "slip" recommended in a previous post, practice a bit with your current binoculars to see whether you are satisfied. As he mentioned, with 10X binoculars, hand shake can become an issue. I do a lot of bird watching and would not use anything above an 8X. If in practicing 10X is okay with you, then you are okay, but practice.
The other issue that immediately sticks out is that you say that you have 10X50. Those are very large binoculars. Weight is again an issue in that it induces more hand shake. Plus, they are very large to pack.
Bushnell makes a wide range of products from fairly inexpensive to very expensive. No telling what you have. If you do consider getting another pair, I would not consider the top price brackets in that from what you said you have not had much need for binoculars. You might consider a modest step up in choosing a lower price pair that has BAK4 lenses. What are they? Almost all binoculars, including the cheapest, focus very well in the center of the viewing field. The edges of the viewing field are a different matter, however. With BAK4 lens, the whole field is in focus. That means if you initially spot something and it toward the edge of the field, it will be in immediate focus and easier to shift over to put the object in the center of your field. But, again, don't go overboard on price. You don't use binoculars that much.
Finally, a tip on how best to view something. Most people, when they see something that they want to see with their binoculars, look down, put the binoculars up to their eyes, and then start scanning back and forth trying to find what they wanted to see. Often, they have a hard time getting the object into their field of vision. ("Where it is?") Instead, look straight at what you want to look at, don't waiver, and bring the binoculars up to your eyes. Whatever it is that you wanted to see will automatically be in your field of vision from the get go. This is something that you should practice.
