The only problem I have with this tool is price

For sure there is a bow in your wire and some set back - so when your rigger is down 80' it might be actually running 65' or something.
I usually just crank my sensitivity up to 100% on my HDS unit and see where the ball is trailing and make adjustments.
Once I'm happy I reset to the correct sensitivity and off we go. The amount of bow on your rigger is fairly constant given average trolling speed - so it takes a bit of experience I find.
I use speed off the GPS head unit but have no way of knowing temp at the depth as I don't run a temp sensor off my ball. I figure, as far as temp goes, I just go to where the fish are ............ follow the swarms ..........and adjust my presentation to drag through them.
