Rangefinder with slope adjusted distance.

[Baller]

I just happened upon this and came to the realization how useful the slope adjusted range function is/would be. No more needing to calculate down/up angle of fire into your firing solution. Pretty cool.

On a side note, what do people think of a USB rechargeable rangefinder vs. replaceable batteries?

Nothing really new there, most all of the major players in the rangefinder market have been offering a slope feature for years.

As for the power source, I'd prefer the replaceable batteries for a couple reasons. First, if the internal USB charged battery takes a dump the whole unit is junk as you probably won't be able to get a replacement. Second, with replaceable you can carry spare batteries with you "just in case."
