Higher magnification is useful to see the detail in the distance, for handheld use opt for a 12×50 or 12×60, this is the largest you can use in practice without a tripod.

For tripod use, 15×70 or 20×80 binoculars are great, or a telescope with magnification of 20+.

If you have a room or a balcony etc, with a fantastic view consider some of the the larger models available, e.g. 22×100, 25×100, 20/40×100 etc.

P. S. You’ll definitely need a high quality tripod to take advantage of these larger models.
