[QUOTE="grubstake, post: 290764, member: 4012"] To my knowledge, Minelab have not publicly advised any factory upgrades during the quite lengthy production runs of the 4500 and 5000, however I have noted some users here and elsewhere commenting that the newest 4500's seem to run quieter and more smoothly than older examples. This 'improvement' may just reflect a steady deterioration of older machines, with wear and tear exposure to vibration, impact, heat, dampness, dust, etc., taking their toll as usage hours mount up. Not unexpectedly, a brand-new, freshly calibrated, ex-factory machine should perform somewhat better - as a potential buyer, I'd certainly hope so! Another factor that may also come into play is that the production life-cycle of modern electronic components is often quite brief, with new, revised, higher specification chips continually appearing, as manufacturers compete in the global marketplace. Hence, it may be the case that today's 4500s are built using currently available parts that are not identical to those that were used initially in the model's life, potentially resulting in a discernible improvement in usability, without necessarily being considered an upgrade by Minelab.
