It's so easy to be distracted and lose your count when counting a succession of items or events, one by one. A Keson tally meter will help keep you accurate and honest when you have to report a total, as high as 9,999! Traffic count? Golf score? Fishing catch limit? Meeting attendance? Number of people entering or leaving? Bundles of shingles? Wheelbarrows of concrete? Whenever you are counting one-by-one to a number of more than 20 or so, it is sooo easy to have your mind wander or be distracted by someone talking to you. Can you accurately pick up where you left off?...or do you just have to fake it? For accuracy...ONE BY ONE!!!!
