Yes good unit for sure!!!
Don't trust the Hodograph in heavy iron...a co located small non ferrous target in heavy nails will mimic a piece of iron signature..starts high a swirls back to the left hard like iron likes to do..
Basically the hodo is like Signagraph off of a Whites except it links the points together instead of raising lines along the bottom like on a XLT
its neat but its nothing new...on a Signagraph form whites you may have a coin line and a foil line raising up simultaneously on a 71 it does the same but it creates a line between them and holds for awhile per users hold setting speed..
you'll notice solid lock ID usually have a straight up slightly bent line...any ID unit can report about the same as the hodograph...Its when the ID starts wavering is when you get the timed reference lines..Those graphs make it easier to see when targets are jumping ID though..Yet still don't trust them in mineral or heavy trash..always use the tone first and Visuals as a reference..
First time I ran the RA71 I knew the concentric was the secret sauce coil...Not fond of the DD on this unit when compared to the Concentric.
