Do you have to separately "look up" lead angles for various "own" ship intercept heading(s) combined with different torp speed settings? Incidentally, I'm in the process of making a spreadsheet that does just that and that's why I question whether this device accommodates these various torp speed/intercept angle combinations.

For instance (SH4): using the vector analysis attack rules and the in-sim measuring tools (and just a zero gyro angle shot to keep things simple):

Let's say you are 80 degrees to the Target course using a Mk 14 at high speed (46 kts). and the target is moving 7 kts. The lead angle is approx. 8 degrees (set the optics to 72 degrees).

If you use the Mk 14 at slow speed (31 Kts), and everything else remains the same, the lead angle is approx. 12 degrees (set the optics to 68 degrees).

These lead angles also change according to the "own" ship course relative to the target course

For example again using the Mk 14 at high speed (46 kts), and the target is still moving at 7 kts, but instead you are 45 degrees to the target, the lead angle is approx. 6 degrees instead of 8 as above.

and if you use the Mk 14 at slow speed (31 kts), target still moving 7 kts, and you are 45 degrees to the target, the lead angle is approx. 8 degrees instead of 12 as above.

Nowhere in the tutorial(s) for this device did I find anything allowing for different torpedo speed settings for the various lead angle computations. I suspect (though I may be wrong), that the device is probably only good for a specific speed torpedo (maybe the German torpedos that were in use).

It’s there. Please watch the lead angle ones carefully. It’s simply a matter of aligning the correct torpedo speed on the speed ring. The examples I put in the tutorials are just that - examples. They don’t mean that the numbers in them are all you can use. A slide rule is a calculator. Just as you can punch whatever numbers you want into a pocket calculator, so can you align whatever numbers you want on a slide rule.

Be advised though - the distance scale is calibrated to meters. All that means to go to imperial though is one extra step, not a big deal. That has no impact however on lead angle calculations.

Thanks... This makes my spreadsheet effort ridiculously obsolete especially since the onscreen measuring tools are subject to pixelated interpolation errors. :Kaleun_Cheers:

As a suggestion, I would love to see a version of this as a standalone PC app using a mouse also. (NOT installed in-game as a tool). Using an android is kinda finger shaky for me especially with the enlarging necessary to read the scales. Be glad to pay extra for such a version.

edit> It would also help the tutorial process if the tutorials were available on the PoutyBatFace Studios YouTube channel so that someone could view the tutorial while handling the Attack/TADS disc WITHOUT switching back and forth from the tutorial.

Very good suggestion!

There is a variation of this for PC, which I've been using on MS Surface, called Solution Solver. https://www.subsim.com/radioroom/sho...19&postcount=1

It's not the same but has some of the same functionality.

I'm pulling Sub Buddy down on my iPad right now. Can't wait to give it a go!

Absolutely love it! This is what I've been waiting for, and have been trying to find the time to do myself. I'd much rather pay someone for it though. :D Many thanks to the dev team and all who supported in making this happen.:salute:

If I may, I have a suggestion that I would love to see happen with this product. On the front-side of the attack disk, would it be possible either via a switch or something, to unlock the outer ring? The logic behind this is that I could change course after setting up the enemy course and AOB, etc, without having to update the rest of the disks simply by rotating the outer ring to reflect my new course.

I hope that makes sense, and thank you for such a great product! Pulling this tool out adds a new layer of realism as well as the improved upon graphics and dial alignment. As a fan of the old style circular Jeppesen Flight Computers, like the CR-5, this is right up my alley. Now if only there were a physical version. ;)

:Kaleun_Applaud:

There are template files around here in Subsim if you want to DIY. (like the link in my signature) They precede Sub Buddy and it is based on them. So you can make a cardboard physical implementation of it. It won't be exactly like the Sub Buddy disks. Sub Buddy is made with it's own twist on it. On the TADS side it uses 2 orders of magnitude per scale (as opposed to 1 order of magnitude) and adds a tangent scale.

I agree that the dark brown relative bearing disk should be rotatable for easier use. With my physical template disk I grab and hold the (white) compass disk with the AOB disk and other pointers clamped together to set ownship course by turning the brown disk underneath.

There's an Android Emulator available for PC called Blue Stacks. It's free and Sub Buddy runs well on it.

Sub Buddy 2.0 is almost here!

Calling out to anyone on iOS (initially) if they'd like to volunteer to beta test Sub Buddy 2.0.

As things get closer to release (weeks) we'll be inviting 'droid owners to join in the Beta.

If you'd like to join you'll need an iOS device running iOS 12 or better, then please PM me with your Apple ID Email address and I'll add you to our beta testers.

New features and suggestions are behind the push for Sub Buddy 2.0, and if we're still missing something you want, please get in touch.

Thanks to the sub community.

Stay safe out there.

Sub Buddy Team.

Ya Mean I dont have to do this in my head anymore?...All those years on Subs doing Mental Gym,,,dang all I needed was a smart phone..LOL

Are the Sub Buddy developers around anymore? I have a small bug which I reported via their contact email and I have yet to receive an acknowledgement.

I’m right here. Are you on iOS or ‘droid?

If iOS email me at support@ideasoftware.uk
If ‘droid email Dax at support@subbuddyandroid.com

We haven’t received any recent support requests this year at all.
