Yep, your angles to %grade are pretty close. I found another inclinometer made by a company called Rieker, may be worth checking out. Has a nice look, and they have been around awhile.
I think you can buy direct, but they are also stocked at West Marine.

I want to better understand what a true 40 degree side slope feels and looks like.

You'll roll over!
A H2 cannot (safely) traverse a 40 degree side slope, it can traverse a 40% side slope.
A 40% or 60% slope is not the same as a 40 or 60 degree slope.
Percent slope is calculated as the altitude change for a horizontal distance divided by that same horizontal distance. IE: A 40% slope is one where it rises or falls 4 meters for every 10 meters traveled.
If I recall correctly, the equation to get slope % from angle in degrees is percent slope = tan(angle_in_radians ) * 100%. A 100% slope is only 45 degrees.
A 40% slope is 22 degrees.
A 60% slope is 31 degrees.
Do not confuse slope and angle, they are two different measurements, and disastrous results may occur if you confuse the two.
Ric, If you want, I'll pick one up at West Marine and mail it to you, just LMK. <HR></BLOCKQUOTE>
