When I first got back into MDing last fall, I didn't have the cash at the time to get the detector I really wanted. So I picked up a BH Pioneer 101 used on eBay for about $40.00, and it worked out great. My daughter is ready to upgrade from the $29 Radio Shack special to the Pioneer 101, and my new ACE250 arrived 2 weeks ago, so I'm ready to let her use it! I think your boys would have much better results with a starter detector like that, a cheap BH or Radio Shack Discovery, which is BH anyway. Maybe you can bury the Jetco and see if they can find it with a BH, lol! Good luck to you and the boys!!
