Hey Dan... if you're thinking about electronics, Mike Frankoff and I both outfitted our boats this year with new gear. We both chose the Lowrance HDS7 touch, with the Navionics Platinum Plus mapping chip. Outstanding detail, it is like having google earth on your dashboard. For what we do - navigating backwater marshes - that level of detail is a real plus. When we were down at the Arroyo a few weeks ago they were a huge help. Made my old unit look like an early version of "pong." In addition, the sonar features are pretty amazing, something you might need on the new panga far more than a flats skiff, since you may be doing more structure fishing at the jetties, etc.
Many different systems out there, all of them excellent - it really comes down to a chocolate/ vanilla decision.
Happy to talk more about it - PM me and we'll can discuss if you like.
Congrats again... GDS
