Agree that side-by-side contemporaneous testing is the only valid way. Yes, logic would seem to dictate that later hw would be more compatible, but my convert is an early model and has comparatively good accuracy. That is the reason why I am prepared to revert my convert to 3790, and convert my virgin 3790 to 3490 to see what happens with the accuracy on it. But it may be more important to retain a totally original 37 as a known standard.Quote:

It seems that the level of accuracy among f modern Garmin GPS is very similar, enabling even a good comparison parameter if we do not have a 3790 original. My 3790 is recent, serial number 381xxxxxxx (sorry, forgot the rest, lol) PCB: V8 8GB 035 DA TC GM. The 3790 of TadFerreira is s/n 380xxxxxxx.
All possibilities are valid, somehow we will get there ..
Umm, so it appears that not all 3790 Serial Numbers are in the format of beginning with 1W8 etc as my 2 are. Oh, well another shaky theory of mine 'out the window' maybe. However, it appears TadFerreira's is older than both Angelo's unit and Caty's unit. Another 'out of left field' thought of mine, both Caty & I have converted and reconverted several times. But how could that be related to accuracy ...Quote:

I hope Loly's doing his Swan on Pond act and working hard undercover again.
