All consumer electronics must be clear so that contraband can't be smuggled in or out. I believe the circuitry of the 29, 39, and 49 is the same.
The SRF-59 was a bit touchy to tune. The SRF-39FP and presumably the others tune a lot more smoothly. I have an SRF-49 and it does. Message: 3 Date: Fri, 28 Feb 2014 22:05:12 -0800 (PST) From: "R.

I have the black SRF-39 and it works well. How is the clear prison model different? I always assumed they were identical inside. I don't see much difference between MY SRF-39 and the SRF-59s I bought about a year ago... they seem very much the same. The build quality seems better on the SRF-39, but that is a subjective judgement. I don't know how much the newer SRF-59 models vary radio to radio off the production line, but mine are pretty identical... and they work great. Mark B.
