The higher wattage allows 3 main things when it comes to depth finders.
1. It allows the sonar to reach deeper depths (not an issue around Kentucky)
2. It has a stronger ping that gets sent to the bottom. This allows you to see your better on the screen better. This is very important when you are trying to watch your bait in instances such as drop shotting.
3. Because it has a stronger ping, it will allow you to distinguish between baitfish and your lure or a bass.

Hope this helps.
