What is the difference between the PU-50 I, II, and III ??

I never see the three spelled out, but I bought some extra D-ring screws in case I wind up with one without a screw or the coin slot only.

I believe the difference is the PU-50 I does not include the screw. The PU-50 II includes the screw which has the nice feature of being able to tighten the screw with a tool, coin or using the collapsible thumb screw flap tightening with your fingers....no tool needed. The PU -50 III includes the screw but you need a tool or coin to tighten it. The PU-50 II is the best of both worlds.

I think it is the small noduals for use as accu-pressure and a cd of how to use them; This is my best guess. I did go with the 960 Limited and we love it.

The 603 IIs have slight improvements over the first generation. The 603IIs have a lock to keep your flash in the hotshoe in the transceiver, the original 603 does not. The 603 IIs also have the switch for the power and to set transmit or receive on the side. The original 603 had the on off switch on the top which people complained was blocked once you put the flash in the transceiver 'a hotshoe. Other than those physical differences, I'm not sure about any other differences but there may be others.

Hi, not sure what the difference is exactly, but I must admit that I find this one much better than the previous one. It is lighter and more durable so I fully recommend getting 83 slow. Sorry I can't be more of help

The p-51 is much larger and duller. P-38 was a better quality. I am still using mine from the Viet Nam era

The main difference is flow rate and pressure. If you are pretty much running stock the 90gph is recommended. If you are tuning your engine for higher horsepower = more fuel consumption, you will want the 165 gph unit. I believe the AD II has an adjustable pressure regulator.

It is basically the same, but the One is a better, improved product. I understand they do not make the Ultra anymore. The Ultra is not as accurate as The One

Difference is size and weight, the 500p is 2.7lb, the 500 is 3.3lb also the dimensions are different

I don't know of any upgrades other than the trigger. I would also look at the newer NP-2.

I am not 100% sure since I do not own both systems, but when I was looking I bought the military one for the price just in case it fell apart on me right away. I also noticed, I think, the width of the strap and the trap color. Other than that I do not really believe there are too many differences. I enjoy mine and use it three times a week and it still looks like I took it out of the box.

According to the description I found in Japanese, DS-50 has the standard size, while DS-30 is more compact. Other features are the same for both models.

Im not sure, I cannot find any info on the PS-30, what I did see though is that the PS-30 is a hammer drill where the 31 is just a standard drill whit variable speed settings. i like the 31, as it is small for smaller tasks and can get into smaller areas. You cant go wrong with this combo specially for the price.

the BB-60 is more aerodynamic looking as it is the newer model. the nozzle on the BB-50 has more metal in the handle making it feel more solid.

The III is very slightly improved over the II and a bit cheaper... It works well but you lose a stop on your lens and on some cameras you lose auto focus...

I don't know but have heard that the II is slightly smaller. It does fit the III easily and perfectly.

There are only two types of CF cards, I and II. Ultra II and Extreme III are just trademark names for SanDisk products--fast CF cards, but still just CF cards like any other (same size, shape, etc.). Any CF Type I/II reader will recognise and work with any Ultra II/Extreme III CF card.

The primary difference is the addition of an on/off button on the front panel of the 641P. As far as I can tell they are identical otherwise.
