What I need educated on is how does one choose a 12-40 vs. 20-60? I guess it depends how far you want??
When it comes to choosing a magnification, it also depends on the typical hunting conditions one hunts in. Hunting conditions vary greatly based on humidity, fog, wind, dust, pollen, heat waves etc… and these things will decrease your image quality the more they are magnified. Here’s where a 30X power will be better than a 60X power. However, if you hunt in clear and calm conditions, here’s where your 60X power will give you an advantage.
The other factor is the quality of the optical system. No matter what, the more you magnify – the more the image quality decreases. However, there are some spotting scopes out there that lose very little quality even at 60X. Here’s where the old saying is true “you get what you pay for”. This is where you should invest in your spotting scope.
When it comes to choosing the size of the objective lens, the larger the lens typically means you can see more of the object and the image quality is better. This of couse is assuming you are comparing two scopes of the same quality. However, it is important to understand that a large lens with fair image quality is not necessarly better than a smaller lens with higher image quality. In other words I would go for the quaility of the image versus the size of the lens. There are many types of glass out there that one needs to consider (ED glass, APO glass, HD glass & fluorite glass).
Other things you may want to consider when choosing a scope is the weight (spot and stalk hunting versus scouting from a vehicle), eye relief (if you where prescription glasses or shooting sunglasses), whether it is waterproof of not, if it comes with a protective covering case, and if you want to get into digiscoping (taking pictures with your camera through your spotting scope via a camera adaptor) or videoscoping (same as digiscoping but with a video camera).
There’s a lot of choices out there – so get a budget, find which scopes fall within that budget and do a side by side comparison.
