I purchased the viso 2 after I finished my aff and put about 30 or so jumps on it so far. Really easy to read during freefall and under canopy. A little confusing at first to access the log information it stores after each jump. After a few times playing around it's as easy as operating a cell phone or any other electronic device. Logs you exit alltitude deployment alltitude top speed during freefall and under canopy all very good to have for jump log info. Would recommend purchasing great deal and functionality for the price.
