you cant run both units at the same frequency, as the trandsucers will clash, you must run each on a different frequency. yep I understand why you want to see it but it wont work.
I have put the post up to try to explain how the units display information, it is not about bagging one brand over another, very few people have the opportunity to see how different units display information directly side by side.
I will endevour get some footage of the units in the same modes and post the results, weather has been crap so, I have been keen to fish and not video..
Maybe I make the deckie drive while I fish, thats a thought..
