I updated my irst Simplex + to 2.76 just a day or two before 2.77 was released, and just benefitting from the new Park 1 mode made it a terrific update. Then two months ago I bought my 2nd Simplex + from 'Kickindirt', my dealer friend, and it came with the 2.77 which provided the 'Mute' function which I like. It already had the enhanced Sensitivity addition in the 2.76 update.

When Nokta / Makro release a smaller-size coil, which is a desired need in the metal detecting industry, I'll likely upgrade my original unit to 2.77 and keep the smaller coil mounted on it. Currently I have the mid-size 5X9½ DD on my 2.77 outfitted Simplex + and am headed out to use it today, as a matter-of-fact.

Your original 2.68 version will work Okay, but I encourage the update to get the added Sensitivity and especially the added Park 1 mode. It's better, too, for USA coinage.
