That’s a good approach, if you have an iPad, download the Navionics Lake Maps App, use it for navigation and finding locations, then use the LX-9 to fish. The RT-9 is an much more expensive option to do the same thing. Until they enhance the software for ease of use and visibility, I’d wait to buy one.

I have an RT-9 and have been using it this winter for about 2 months. It’s an impressive unit in concept, but the software use-ability still needs refinement. Each screen has a number and menu selections for each screen can be changed to either sonar, GPS or camera. The visibility of the menu buttons is very difficult to see, especially the numbered screen which is how selections are made. Go to a retailer and you’ll see what I mean, don’t buy this unit without trying it out at a store firsthand to see if it works for you. The menu navigation is fairly straight forward but again, visibility is difficult since the font is tiny, especially in an ice house. Secondly, the battery life with a lead acid battery is about 3 hours, not very good, and less with the GPS and camera operating. I went to the K2 Energy lithium ion battery and improved my battery life dramatically. It’s very important with the lithium ion battery to buy the charger for the K2 battery as the Marcum charger that comes with the RT 9 does not charge this aftermarket battery properly. Once I bought the K2 charger, the battery life extended to at least 8-10 hours on Sonar mode. The RT is very expensive and even more so with the K2 battery. You can achieve the same results with the LX-9, with no GPS. It’s working for me and I like the integration of three options.

Have been using my RT-9 since late December and there are several issues that still need to be worked out on the unit. First, battery life on the standard lead acid battery is less than three hours even in just the sonar mode. If you add in GPS or the camera, the battery life is even shorter. I went to a K2 Energy lithium ion battery and gained an extra 2 hours on the battery life, still not very long compared to other units, the RT-9 sucks power like crazy.
Secondly, the menu and setting select buttons are very small on the screen and very difficult to see. The menu selections are fairly intuitive, but it take some practice to get it right when you first get the unit. Visibility of the menu and setting selections need to be enlarged and improved with the next software update. This unit needs further refinement but it is going in the right direction.
