They both do the same things...
Humminbird = 1 transducer
Lowrance = 2 transducers
Retail price - Humminbird 899ci HD SI combo will be $100 bucks less but Lowrance Gen2 7 Touch Bundle has a $200 rebate until July 5th.
I can go into more detail here but I would offend some folks so give me a call if you like. I would be happy to visit with you direct or shoot me a PM....
