The one thing this article completely misses is: This just completely changed the Search and Rescue world!!!

Right now it cost about $20k to get a sonar device that is useful for searching lakes for missing people. Even once you buy the device, trying to use the darn things are time consuming and complex. You need to do some hands on training before you can even deploy the equipment.

This would allow any SAR team to have a device of searching bodies of water!!! This is a major game changer
