Found a sonar and a (now broken and thrown away) GPS and a case laying in the road near my house. As noted above, GPS was broken and way beyond repair, so I threw it away. The case is badly torn and should probably be thrown away as well. The sonar still works. I plugged it in to the power cord for my same brand sonar and it powered up and appeared to be fully functional.

If you lost it, PM me and tell me a few key things, like the GPS brand, brand of the case, and the brand and model of the sonar and I'll gladly give it back to you. I might still be able to dig the GPS out of my garbage and give that back also, but it really is well beyond repair.
