IF you can find an 898 or one at a decent price!
IT IS plug and play, the only
additional thing you need besides the Ethernet cable is the AS EC QDE which costs around $25-$30. So if you contact
www.UniversalMania.com (I prefer by phone) or see it listed here:
http://www.universalmania.net/humminbird-as-ec-qde-ethernet-adapter-cable/Heck even Walmart sells it online - I am running that exact setup and the $25-30 surely offsets the cost of the 898 if you can find one, I have found they are going for over $1000 if not $1200 many places, maybe you can find one for a lot less.
At that point I would look long and hard @ another 998 which Universal
does have some left at a nice price. I really like the technology sharing of Sonar Data between the machines, and having a HS puck makes both track really well.
