In 1974 I bought a new Bushnell Spacemaster II spotting scope, and a 20x eyepiece. It is not as small as the very small fixed power scopes of today, but it is daypack size. I have carried it deer hunting and antelope hunting. The 20x eyepiece is ideal, and I do not need to carry a tripod.
On the job I had a more expensive B&L variable up to 60X. It was just about unusable on hot days because it would pickup all the heat weaves. A good feature was the lens adapter for the 35MM camera.
I think because of its smaller size the Bushnell Spacemaster II with the 20x eyepiece was the better of the two.
While the technology has improved, and you think you might be packing it on a hunt, go to the different sites and compare weight. You might have to visit manufactures websites to get the weight. The extra ounces add up in a daypack.
Now days I would go for one with a variable power eye piece, but avoid models that replicate a shoulder fired rocket launcher.
