They have agents in most countries and also sell via eBay shop (search eBay on carscope_ditex)

On the otherhand if you want a simple starter level PC USB general purpose scope at a bargain price checkout the Owon 11022i --- it is a lot better than the Hantek 1008 but will need input attenuators for checking coils and injectors

You will find very many comments accross the internet and in this forum on Hantek scopes, the serious experts reviwing them say the sampling rates they quote are way over claimed, the software is horrible to use and build quality generally inconsistant and poor.

I love the Owon as well and will keep backing you up on that.
The settings kind of reminds me of the Sun LS 2000 that I had but died.

No disrespect, because your reports on USB scopes and other variants are priceless for those of us to whom these tools aren't readily available.
For this very reason the question remains 'Why not a low cost bench scope (like the Rigol ds1054z)?'
Surely being tied to AC mains cannot be the only deterrent since that wouldn't matter if working in a garage or back yard.
Is it the lack of automotive specific programmes/configuration?
Incompatible probes, adapters, connectors?
Remember many of your followers (you'd probably be surprised) can only look at videos and read here and at other useful forums. We cannot experiment with the tools and return them. Nor even see them function live. Re-shipping gear if we make a bad choice is out of the question.

Some seem to think it's too expensive for what it is,i bought mine for £700,when i sold it it was 'as new' and it took me months to get £300 for it!!

All mainstream losciloscope have a standardised 1 meg ohm so using automotive accessories isn't a problem. As I have posted many times lack of automotive presets on any scope isn't a major issue, neither is the lack of setting for a 20:1 attenuator -- simples - just use a 100:1 attenuator instead Rigol scopes keep geeting mentioned I know they are pushed hard by a certain party on the internet but the screens are smaller and the price.

Aside from portability reasons, bench-top scopes are not ideal to use because they are mains earth grounded/referenced (that is, the BNC ground is directly connected to earth ground) via the scopes power plug plugged into a wall outlet. This presents problems when trying to measure non-earth grounded floating voltages typically found on vehicles.
There are ways around this limitation of the scope (one is by adding a differenital probe) but just realize using one without taking extra steps might give inaccurate measurements.
It's worth noting that even portable oscilloscopes that run off of battery power can potentially be subject to mains grounding and throw readings off if the device is plugged into a wall outlet/charging at the time of use and its charger is not isolated. The same goes for charging via USB. .

Aha! Priceless.
One sincerely appreciates this information.

I have been working on 4x4's and Jeeps all my life, and now I am just getting into scopes, realizing with todays technology a graphing multimeter is not cutting it anymore.Not a professional by any means , but do consider my self a full throttle DIY Guy...lol
With out hi-jacking this thread,, I do have a scope ground question, which may be different from the ground question on this thread. As a new member here, was not sure if this was worth posting a new thread..
I am between the Autel 4 channel automotive Maxiscope MP408 vs the 2 channel PICO automotive scope with the new bnc plus upgrade that recently came out.
I am trying to understand the terms of floating grounds vs common grounds on the scopes themselves ,,, where all the channels are all grounded together or like the pico where each channel requires a separate ground on the different sensors that are being tested
I believe the Auto Maxi Scope is under the common ground rule " not sure, appreciate any input on that",,,?
How does that change the way I would safely use the scope? IE The AUTEL STAND ALONE 408",,,,,,,Just use the one negative ground on the battery of the vehicle no matter what sensor and how many channels I am testing on since the scope has a common shared ground? or is it more complicated than that?
If anyone is wondering how I got between thinking of buying a 4 channel Autel or a 2 channel Pico, is due to my limited budget,,, I am heavily relying on the new Pico 7 automotive software to help aid in making that 2 channel scope more of a 4 channel scope with extra work with the waveform overlay option on the their software, as well has the online waveform library.
I Know the Pico is the cadillac of scopes, but the Autel has 4 channels and I can afford it. Any tips? Looked at the Mic Sig portable automotive scopes,,, seems tempting,,, any inputs?
Thanks
Don
