    I have a detroit in the rear of my 101 and have no issues with it on any surface including sand/dunes - you would not know it is there.

    I can’t vouch for ATB’s as I have twin ARB air lockers. I was on Moreton island at Easter and the Tangalooma bypass was very dry/soft with deep wheel ruts. My first pass at 20psi with no centre diff lock was a struggle. My return drive along this track was at 12psi and centre diff lock engaged making the drive so much easier.... especially having to drive around bogged P platers.

    no need for lockers.... just air up at the other end.

    +1, Spot on Mick.
    The chances of lifting wheels in sand is remote so save your quids and buy a good compressor so that you can easily alter your tyre pressures or better fishing gear with the money instead

    Landie "Sand Mode" may be OK for sand (know nought about it) but a normal Traction Control system in loose sand is a big no-no. It should be turned off.

    Nah! If your D2/Defender TC is over reacting in sand it’s purely tyre pressures.

    TC on sand isn’t a problem if you understand the tech, in fact I consider it a benefit - seen it do more good than harm.

    I agree.
    TC is definitely and advantage in sand

    I am another one......lockers don't help very much in sand.....tyre pressures/tyre type/size, light weight and grunt do.

    Interesting reply.....
    My mate who has a 80's cruiser has a Detroit Locker in the rear (nothing in front) and when we went to the cape a few years ago, he somehow managed to break CV's & a front axle as well. I found out that he did a fair of driving up the Cape without the Centre Difflock engaged. He has since changed his driving methods where he now locks his CDL when offroad. Looking back, He now believes that having the Locker in the rear and "not" engaging the CDL caused extra stress on the front drivetrain, resulting the issues that he had. I don't know if he's right or wrong but since changing his driving methods and engaging the CDL offroad, he's had no issues with the front drivetrain at all.

    It's a pity they don't make a ATB (ashcroft) for the rear of Salisbury diff Defender....

    Both locker and Detroit on sand (mud, loose shale) are great - until - you get a cross slope. Then they will try to slide you to the low side under power.. this isn’t always desirable or safe!

    The least obtrusive is the selectable locker - when you don’t need it you wouldn’t know it’s there.

    The ATB is the all rounder, relatively unobtrusive in daily use, engages when slip detected and has a pretty decent amount of power transmission to ground.

    Detroit’s - my opinion are horrible, always engaged they unlock rather than lock - increases wear and some driveline stress and some notable handling changes when turning etc.

    I was once a staunch advocate of Selectable lockers.

    Now a fan of ATBs and driver knowledge.
