- with the verus do I need a high amp probe? ( in the settings on the verus it has no option for such)
- what attenuators do you reccomend for the verus? Or do I even need any.
- what other accessories do I need for general diagnostics as in Paul's book?
(I will include pictures of my cart with AESwave.com.
It seems a little dumb but I thought about just buying the maxiscope as well since it comes with a good many accessories I could use and I could just add a low amp probe and cop probe.

You won't need an attenuator with that scope.

The low amp probe will be good for current ramping fuel pumps, injectors, ignition coils etc. That kind of versatility makes it a valuable tool in my eyes.
The high amp clamp will really only be useful for relative compression testing. On some cars with small enough battery cables, the low amp probe will be sufficient. Really it's just the opening of the jaws that limits it as far as relative compression testing. You can also perform this test with just a lead on the the battery, AC coupled and inverted. So a high amp clamp is not such a priority for me.
Secondary probes are cool. Some techs are very talented and gather a great deal of information from a secondary pattern. I don't really do a ton of secondary testing with my scope so I made one instead of buying one. www.scannerdanner.com/forum/diagnostic-t...secondary-probe.html
I haven't had a secondary ignition problem that I couldn't nail down with just an adjustable spark tester, a test light and a visual inspection of the plug, so the value of that tool is limited in my eyes. Again, just my opinion.
There's multiple threads here on the forum about home built ones www.scannerdanner.com/forum/lab-scope-di...need-to-buy-one.html but nothing wrong with buying a quality unit.
The back probes are a must, let me know if you go for the AES Wave ones in your cart, I've been eye balling them
Piercing probes are a must, but not all are created equal....
I've wasted some money on junk ones. The 5 pack AES wave ones were quite disappointing. The power probe ones are great but have a male end and require (but usually include) an adapter. Phil's Probe looks good and has Scanner Danner's endorsement but is a little lofty price wise for my cheap heart.

I changed my cart up a bit and decided to go with the paddle and clamp kit instead. Am I wasting my money with the "primary ignition lead for snap on". What's so special about it if the snap ons are already attenuated?
Don't know about primary ignition lead. I've never seen anyone use it. Maybe some one who has can chime in?
The piercing probes are a matter of preference. There's a large portion of the automotive repair industry that are opposed to piercing wires, and that's perfectly acceptable and they have a compelling argument against it.
They are a must in MY routine, which may differ from someone else's.
I do like the looks of that paddle probe. For the trouble of making one, I thinking l think the cost of that one is justifiable. I haven't it used it though so I can't speak to it's quality. Maybe someone can share their experience with it.
I don't think you would be wasting your money on any thing that you actually use to work on the car, or use to further your understanding.

I'd never seen one of these, either. :silly: Looks like a simple attenuator for viewing primary ignition spikes over 200V.
Kinda tough to justify the price. I rarely do primary ignition testing, and if I am, I'm zoomed in on the burn line.

It's a matter of access. I use the AES paddle. It's flexible at the end and needs to be because sometimes I have to jam it in beside or behind a coil to get a good reading. I prefer it over the Wyze simply because it has that bit more ability to be positioned. The Wyze is fixed and so is little more limited in being able to get at those coils way up under the cowl, wiring, heater hoses, etc. There's probably coils where the Wyze reads better and easier, I don't do enough of that style of diagnostics to really exercise my tools like that. Safe answer would be to buy both.

I could not get at one of the coils at the rear on a 6 cylinder Nissan. Something flexible might have likely.
Also I did not like the Wyze probe with my Vantage pro because the signal was too low and i had to switch over to a voltage mode to view. But just my personal preference and BTW I do like it with the PC based scopes.
The Paddle because it is flexible and has some surface area to it may work better on certain vehicles or certain coils.
I have found some of the home made ignition probes or leads work just as well or better. I wound not spend too much money on one.
Yes to the OP a low amp probe some back probe pins and a couple of piercing probes for if you cannot do it differently just put crazy glue on the pinhole when done. But never do it on ABS sensors or where the salt or water will get at it.
I found the Hantek accessories from Amazon or Ebay to work well and for low cost. You typically need a BNC to banana adapter with your snap on stuff.
Anything from AES Wave usually functions well and is durable.
