If you want a laser rangefinder that has slope-calculating abilities, then you can typically expect to pay in upwards of $300. That's what makes the TecTecTec VProDLX 1000 S laser rangefinder unique, as it comes in at $200. The product is rainproof, measures out to 1,000 yards, and it's able to perform all of the great functions you'd expect from a high-end laser rangefinder.
