They are pretty awesome. Getting them setup properly and learning to interpret what you are seeing is the biggest thing. I have a 7 touch and 9 touch on my boat and wish i had a 9 and 12. The 7 on the front is a little hard to see at times but not bad.
You should put the larger unit in the front of the boat. The 7 will be closer to your face at the console than at the bow. The only downside is if you’re running multiple split screens. If that’s the case, you might be able to get a second unit for the console just for mapping [something like an older HDS-5] cheaper than getting a 9 and a 12. I have a 9-touch w/ LSS-2 bundle that I got in February, but haven’t installed yet… My plan is to use it at the console and move my older Gen 1 HDS 8 to the bow. I guess I should just bite the bullet and take the boat our to Clark to get it installed.
To the original poster…
The Lowrance units are great. You just need to make sure that you spend some time on the water with them without fishing. Learning to interpret the data on the screen is critical.
I can acutally see the 7 just fine except for glare. I can read everything standing upright and not having to squint. I like to run multiple screens when running (Map and sonar at full speed and map, side scan and down scan when idling along). I dont use side scan in the front. Mainly I use it for Downscan and mapping. The glare is really what gets me on the front unit.
I like the bigger unit on the back just so I can see farther out on the map when running and know where I need to be way before I need to be there! LOL
