There is a $50 mail in rebate on many of the Lowrance models right now. My Elite 3X portable kit (bag, battery, ice transducer, suction cup boat transducer arrived today. After rebate I'm in for under $175.
I have a 4X DSI but I mounted it on my kayak semi-permanently. At least the transducer isn't coming out easily. The head unit comes out quickly. Hoping I can swap head units and use the 4X with the ice transducer.
I also bought an ancient AlumaCraft off craigslist and I'll use the portable on that.
I've been searching the forum trying to find the ideal settings for the 3 or 4 for ice fishing.
