Cannon Digi IV good and bad?

[HPORT]

I'm looking at a pair of Digi IV's to upgrade my older Mag10's and wanted to know from those who have used the IV's, the good and bad of having them.

We fish with 4 DR's and I'm currently the only one on the boat who can set them up, net fish, etc... so having a DR that can return to the same depth with a push of a button can come in real handy at times.

I understand the IV's can track the bottom with an optional transducer? Master / slave feature, so if I have the one IV with a transducer the other linked units will follow the commands of the master? One function I could see that coming into play, is when we have a bottom coming up quickly and the monkey is asleep at the switch.

I have one Digi II, that the auto-up key just froze-up on, and Cannon just sent me the maunal for it to set-up the memory functions, go figure...

Anyone have a good Digi II keypad they are willing to part with?

Thanks,

John
