Vexilar SonarPhone Sonar System
The SP100 SonarPhone with Transducer Pod (T-POD) is a completely portable floating WiFi transmitter that can be cast from shore or pulled behind your boat, canoe or kayak. This model is not intended for ice fishing use, the wide cone and overall transducer design is for the open water.
The SP200 SonarPhone with High-Speed Transducer (T-BOX) is a more permanent version that securely mounts in your boat and uses your on board, 12 volt battery supply for nearly unlimited run time.
The SP300 SonarPhone with HS Transducer & Porta Case (T-BOX) comes in a portable system with a carry case to hold the battery and a suction cup mount to put on your boat.

Every ice fisherman should get one of these

Just got this and took it on two ice fishing trips. It's the greatest thing since sliced bread. It allows you to see exactly what is below and tells you exactly what the depth is. It will also be useful on my fishing kayak this summer. It's a little pricey, but as long as it holds up it's well worth it to me.
