deadrise angle at each panel on each size

[Capt Terry]

I have used my Iphone 6s both as a level and a protracter. Also used it taped to the AV plate (in the driveway) to determine trim angle versus my trim gage. Just tried the iphone upside down and it still reads. Turn on the compass app and sweep your finger quickly from one side to the other to turn on the level. It will read the angle in two directions, so you my have to play with it to get the desired angle.
