I agree with the others. A rangefinder would serve you bowhunting better. But I would do as pigiron suggests and hang on to your money for something else. With the distances you most likely will be shooting deer and pigs, you really don't need a rangefinder. Practice estimating distances. If you set up in the same areas, walk off surrounding points - trees, bushes, etc. and know their yardages from you so if an animal is near you'll know. Most of todays bows shoot fairly fast, sometimes 1 pin is all you need out to 20 or even 30 yards. You should be able to keep it within a pie plate. If you have an older bow that doesn't shoot as fast, you could save for a new one.
