IA4PATS Posted June 23, 2015 Share Posted June 23, 2015 I have a brand new 859 ci hooked up to a brand new Terrova. But the depth is jumping all over the place. Any thoughts? Quote Link to comment Share on other sites More sharing options...
slammer Posted June 25, 2015 Share Posted June 25, 2015 I'm no help but have you tried customer service with either brand? Let us know if you figure it out. Quote Link to comment Share on other sites More sharing options...
marine_man Posted June 29, 2015 Share Posted June 29, 2015 When is it jumping? On land, when underway / moving, or?marine_man Quote Link to comment Share on other sites More sharing options...
jac714 Posted June 30, 2015 Share Posted June 30, 2015 Dumb question but are you powering both of them (trolling motor and graph) off of the same battery, this can cause a multitude of problems. Quote Link to comment Share on other sites More sharing options...
IA4PATS Posted July 2, 2015 Author Share Posted July 2, 2015 I called Humminbird, And they said not to use the built in US2 transducer. They are not compatible. I thought the two companies worked together? Quote Link to comment Share on other sites More sharing options...
BartmanMN Posted July 10, 2015 Share Posted July 10, 2015 (edited) It's not that the companies don't work together, it's just the US2 is not a 'good' enough transducer to work with your locator. I've seen the 8 series bundled with the proper trolling motor transducer from some retailers. Edited July 10, 2015 by BartmanMN Quote Link to comment Share on other sites More sharing options...
delcecchi Posted July 10, 2015 Share Posted July 10, 2015 Aren't Humminbird and Minnkota now the same company? Not that they were when the US2 was implemented. My elite 7 works fine with the US2, except the DSI 800 khz is not available. Quote Link to comment Share on other sites More sharing options...
h8go4s Posted July 11, 2015 Share Posted July 11, 2015 This topic was posted in 3 different forums, with 3 different headings, I believe. The issue is that IA4PATS is trying to run a DI unit off the us2 transducer, which is a 2d transducer. It will not work with a DI unit. The problem is a combination of systems that have become complicated, difficult access to information on compatibility between systems, possible misinformation at the point of sale, and a failure of the buyer to do his research. delcecchi 1 Quote Link to comment Share on other sites More sharing options...
h8go4s Posted July 11, 2015 Share Posted July 11, 2015 (edited) Here are links to the two other posts by IA4PATS.http://fishingminnesota.com/forums/topic/204554-trouble-with-new-humminbird/http://fishingminnesota.com/forums/topic/204555-problem-with-depth-finder/Makes for lots of confusion. It would be nice if originators would reply with a "problem solved" post. Edited July 11, 2015 by h8go4s Cheers 1 Quote Link to comment Share on other sites More sharing options...
IA4PATS Posted August 18, 2015 Author Share Posted August 18, 2015 You are right about posting "problem solved". I will try to do that in the future. But I will say I am constantly having to redo my password. For some reason it will always deny my passwords and takes me forever to get a new one to reset. It was the transducer. I put on the one that comes with the unit and works fine.Now, I still can't get it to follow the contour. I contacted Humminbird and am waiting for a response. Thanks for all your help.
