Hi Doug, You may not have meant it that way but I cannot think of any reason why single-handing would require any different kind of GPS than double-handing. I agree with the Garmin 12 choice - the value leader! I have even used it while downhill snow skiing to determine top speed! It is tough and literally can take a tumble without quitting! It also gives you something to do while riding back up the ski lift - watching the altitude and speed... lets you know if the brochures are accurate about the listed vertical distance of each hill.
