Looking at the link you provided, I don't recognize that one at all....My gut feeling is you'd be better to go with a tried and tested model. I paid around $400 for my rangefinder (bushnell yardage pro)....for $99 your probably not getting what you would like.....
Its probably a hunk of crap... If you bow hunt it might be good to read ranges out to hundred yards and so and also if its not in your budget to spend more then maybe... But IMO its probably some junk...
