Input:
Question: Can this unit be used in saltwater, does it have the full transducer kit and does it have a speedometer built in?
Document: I would give it all five stars, but I am having issue with the down image and not sure if its the unit or something wrong with the transducer. I have contacted lowrance and they have told me how to troubleshoot the issue to figure out which one it is and they will warranty it. Other than not being able to use the down image the unit itself and sonar work very well and easy to use.
I would give the unit a 5 star rating but as stated, the instruction's for running through the program's is not very good. If you can't find the dvd just take time going through unit before you go to lake-it will help!! Maybe Lowrance will make a dvd showing all the feature's some day.
Lowrance does not give you all the trick's that this unit can do. The only reason I did is because I had an Elite system before. There is a dvd by the Bass Professor on HD unit's and most of all the feature's on that dvd will work on the Elite system. The only thing I wish I would have done is ordered the larger Ram mount, the 1.5 ball is just not big enough when you are in rough water.
This is the second of the Elite Series I have purchased. My first unit was an Elite 5 and for the price and feature's I really enjoyed it. I purchased the 7 for the bigger screen and it does make it a lot easier to see when you are running flat out across the water. It has most of the same features that the HD system's have at a lot less price. The maps that are included on system are very good and there are a lot of extra's.
I thought I had researched these. Spent quite a bit of time looking a the price point/features of various units. Was intrigued by the downs an feature. But as far as I can tell, it doesn't do much of anything and I never use it, so I could have got a chartplotter a lot cheaper. That said, chartplotter is great. Any maybe I just haven't figured it out yet.
Answer: no
