Steve: After running a Hawk for over 15 years daily with down time in between for constant repairs. Here are several advantages. Constant LCD read out. Both temp. & speed. No more having to average it out when the speed on the hawk is bouncing around. Ease of installation, no transd. to mount one cable from the rigger to the head and two power wires for the head. The whole system can be rigged in less than an hr. including the coated cable and you don't have to pull the boat or drill more holes in the transom. As far as the coated cable goes unless your stacking on it (I don't) I see & have no problems altho I kn some guys that do stack without any trouble. Last but not least. Price, support if you should have a problem is excellent, sealed electronics in the probe. If by chance the o-ring should leak. The only place it can get to is the battery compartment. Not the main board.
Dam Missed my callin. Should of been a salesman. :shock:
