I own an LX7 and an HDS 5. If your fishing inside a hut the LX7 hands down. The one downfall of this unit is glare off of the screen on bright days and even with a matte anti reflection screen shield its still an issue. The Lowrance has a much better screen however there is lag time on the response. My HDS sits on the handlebar of the sled/atv for the GPS and the ice pack for it is collecting dust. If a unit ever hit the market with the instantaneous response time like the LX7 and a high end screen like the Lowrance unit for fishing in the sun it would be at the top of my list.
