    Honestly it depends. Some D-Locks can be snipped by the same size bolt croppers that are used on Cable locks, but only really the cheap low-end D locks, whose only real benefit is appearance, but in reality they would go just as easily when attacked, just due to quality of material.

    No tool will make as much noise as the alarm on that cable lock.

    It's both, like I said before, there's an internal cable around the main steel braided cable and when that is snipped it sets the alarm off. But also it comes with a motion sensor in the head unit, detects movements and strikes and alarms accordingly (Which gives additional protection to the rest of your bike.)

    You're smart with the thinking, using D-Locks for their appearance however a well seasoned thief will attempt anything and would already know that some D-Locks are made of cheese. It's like of like those "armoured" cable locks, that look bulky but in reality are very weak, it just takes the right thief.

    Appearance deterrent is only buying you time until a more intelligent thief comes along IMO, and personally I think appearance deterrents are something that you should not rely on.

    Atleast with the cable-lock, its appearance, would sit happily within a cafe stop or on use on a front wheel, but its actual abilities would be able to rank it to much greater use, providing more security than a D-lock, because SHOULD a thief stroll up to your bike with enough tools to slice through any quality D-Lock, no matter what tools he uses he can't defeat the alarmed cable lock, because it'd certainly alert you, and certainly spook the thief.

    All-in-All, that cable lock is an incredibly Potent lock for its size, weight and flexibility.

    Many thanks for the time you took over that tangoup.

    You make a good case.

    Now to have a good think.

    oh a quick question @Tangoup51

    How long have you used this and what are the batteries like? I am very wary of any sort of button cell (my kitchen scale batteries last hardly any time at all) and especially if they are supposed to be powering what I am lead to believe is a fearsome alarm.

    How long do they last in use?

    I never understand why people do that. It should scream to attackers "bust rear wheel lock, get front wheel free". Two independent locks will always win IMO.

    ETA Most of the time it won't matter, as someone in most large cycle parks will use only a silly string cable and be the first target.

    Some time now, can't pin how long. Probably about a year? The batteries are 4x LR44 Batteries. (Small diamater, fat, watch batteries) the batteries will last a long time, the only significant use they get is when the alarm is screaming its head off, everything else draws minuscule power. Comes with some good standard ones, but Some decent Duracell ones would make it last god knows how long. Probably 1.5-2 years of regular use.

    I've had loads of alarm locks, all of them use the same LR44 batteries, I have such alarm lock on my shed, it's been active for about 1 + year now, so it only draws power when its the alarm is screaming, but the alarm on the cable lock is far more sophisticated and better made so I'd expect it to be also more efficient too. Battery life is a non-issue with these products, your kitchen scales must of been thirsty !

    The lightest D lock I know about is a Palmy Mini Aluminium U-lock at only 358g.
    It's very weak to any attack but it's a good visible deterrent for cafe stops.

    I've dumped some kitchen scales into the small electricals recycling because they ate CR2032s almost as quick as we ate the food. I wouldn't get any more and an AAA- powered set has replaced them.

    I've no problems with an alarmed cable either. I think it's coming up on two years on the batteries. It still does the confirmation arming pip OK but I guess I should test the actual alarm (in the middle of nowhere, with earplugs in).

    Good luck with that, trying to break a mini d-lock that's tight on the back wheel?

    If it can get on the wheel, it can come off too.

    I got four of the Raleigh D locks with looped cable thrown in. £20RRP but a fiver each from Tescos. Look ok, and are extras for my lock up (to attach a load of crap old bikes on top of my main bike [itself secured with much better lock])

    Think it is Protect 100. Very light

    Thanks for this jay clock but i think it may have been discontinued. Possibly explains why you picked it up so cheaply.

    If you don't understand that use of a cable (and I'm not arguing) your mind would have been fried by the bike I saw parked/"locked" in Putney a while ago. Cable looped through both wheels and the passable D lock used to link the loops on both ends of the cable. Weakest link or what?
