Lowrance Elite/Mark-5 DSI
Im not a big fan of buying electronics when they first come out due to bugs and tweaks but it looks like Lowrance has done their homework and tested these units thoroughly. I have an Elite-5 already and was looking at buying this unit to put on my TM but with the speed that they can read at, I think im going to modify my ram mount like the guy did in the link below and find another unit to mount up front.
