What's in it
Map My Woods. LiDAR terrain and grade on every line, the optimal layout for your grade, and a tubing bill of materials by line size.
Maple calculators. Everything the old MES app did, and then some. Draw-off by today's barometer, Rule of 86, tank volumes, tubing sizing, RO.
One app. Sugarbush monitoring with live vacuum, tanks and temps for Sap Spy customers. Sap & Syrup Log with barrel labels comes next.
What testers found, and what's fixed
