I nearly always lock mine. But not everyone here is experienced with offroad driving, so I try not to assume.

Fair enough, and if your post has helped one less experienced owner, then it was worth it.

Just know my comment was not directed at you, but at Ronny. With as much 'experience' as he proports to have, he should have been well aware not to venture on the beach with the center diff open...

In fairness, I was surprised he (RD), was not aware after everything I have seen/read over the last 24hrs

His experience allows him more flexibility, he does not always need to lock the diff to drive well. But not with the QM, at least on the beach.

A bit like how I always use low range for water crossings, because the one time I did not, I had a near miss. Now I always use low range.

Off road, ESC off.
I fell into the trap and have posted before that the Gren has ESC which is an electronic stability control...not traction control. When you engage the centre diff the ESC is now not active which allows the wheels to spin without applying the brakes...my rooky error was exactly that and was stopped dead in my tracks in powder sand heading to the barge at Inskip Point that takes you to Fraser Island the largest sand island in the world, which I have done for 5 decades. I'm not at all in favor of this electronic device because I like to be in control of the vehicle, so when driving hard on bitumen or dirt if the unit senses a slide or slip it applies the brakes to maintain stability. It is not wise to have the centre diff locked while on the bitumen so I would prefer not to have the ESC at all because I have had the vehicle slow me down in a corner at speed were the unit thought best to touch the brakes...not a good feeling. A lot of my early driving days were spent in the bush on dirt roads where you learnt how to control a vehicle at speed sliding...two wheel drive and no electronics.

I get it today on road...safety first...warnings, flashing lights and spontaneous braking...but to me it is dumming down...old fart maybe

I might be misinterpreting what you're saying here @Max. The Grenadier has ESC and ETC.

Versus other makes, the Grenadier ETC requires more throttle and wheel speed difference across the axles for the ETC to wake up and operate on the spinning wheel/s. This can give the impression that it's not fitted or not working.
Robert Pepper tested it against LC300, Y63 Patrol and ND in Part 3 of his Grenadier, Defender, Patrol and LC300 comparison: Slippery Climb Test. Robert observed that the Grenadier ETC (he calls it brake traction control - BTC) works but it is relatively slow to react. Once a wheel loses traction a few more revs will activate the ETC but on a climb the vehicle loses some forward momentum due to the delayed response.

For Grenadier ETC operation see here and here
For the side by side comparison see here.

Someone on here gave a plausible reason why IA might have calibrated the ETC to activate at slightly higher wheel speeds. I can't recall what was said or where it was posted but it made sense when I read it .

Correct but the point I was making ESC is a different system, could be confussed with traction control and is a trap for the uninitiated, if it is not turned off it can stop you in your tracks. The traction control is only available with centre diff locked and is pretty average

While I have always been taught to lock the center differential (of Land Rovers) when off-road, on a recent ‘drive the Grenadier’ event in Santa Barbara (sponsored by Ineos), the demonstration driver stated that the turning circle would be lessened if the center differential was left “unlocked”. Has anyone tested this claim?

That's true, so in tight situations (on flat surfaces with good traction) you may wish to momentarily unlock the centre diff to improve your turning circle.

It's also good practice to unlock your centre diff in campgrounds to avoid scuffing up the surface when making turns.
