Deadrise- The angle of the hull where the transducer is mounted. If you don't know you can download Gemeco's install app and measure the deadrise yourself.

Frequency- The B175 is available in 4 frequency bands. High Wide for fish swimming around in the top 300' of the water. Medium for bottom fishing up to 800'. Low is a wide cone for deep dropping and marking bottom up to 2500'. The High Narrow is for bottom fishing up to 500-600'. 

Plug-All transducer will come with a generic Mix and Match plug on the end, and a short 3' pigtail. The pigtail connects to the mix and match and connects to the fishfinder. This makes it easy to change fishfinders down the road, and easy to troubleshoot problems. You can read our article on plug types for more details on your fishfinder if you don't know what plug end you need. Here are a few examples-
