I just bought this card on July 12th. I used it a couple times in my Helix 5 Combo. Then we just traded in our boat for the pontoon and I made a deal to leave the Helix 5 on the boat. Now I have the Lakemaster card that I paid $124.95 for. It's a month old, used twice and I will take $100 for it. This Humminbird Lakemaster card is also compatible with I Pilot. It's up to you to check and make sure your unit will work with this Humminbird Lakemaster card. Once sold it stays sold. Thanks, Crappie 1
