I ordered a gimbal mount from Humminbird to use on my bench. Humminbird didn't fill the order they sent it to another company ( warner's dock inc) . Warner's return policy will not let you return anything if the BOX is opened. caution should be used if ordering from Humminbird. I got 2 898SI's on my new Ranger and Ranger messed up and sent 2 complete over the counter Bird boxes that they got with my 898's so ended up with 2 extra GPS and 2 transducers .Now since i have an extra gimbal that Ranger messed up i wanted to return to Warner my order. all i can do is send back to Warner and pay shipping to them and they will decide if i get a refund so now i might have a cost of product plus 2 shipping charges and no refund. just verify where your order is coming from if ordering from HUMMINBIRD'S web site.
