DD,
I bought and am using the Pro-Troll Black Box (from Cabela's) and yes it has the Cabela's name on it. The ones I've seen locally have the Pro-Troll name on them.

So far it works great and although I only have limited time on my boat and with my Black Box I have seen a noticeable difference in the number of fish I've hooked into since adding the box. However, I don't have the pulse mode which may be a usefull feature. The coil contacts haven't caused me any problems.

Peri,
MJ is right, however you wouldn't have any electrolysis between a stainless steel cable and other metal components on the boat. You also wouldn't have any electrical current coming off your downrigger wire 100 feet down either which may or may not be good depending on whether the fish are attracted or repelled by that current.

Based on my fishing experience before and after installing the Black Box its definitely worth the $99.
