Dive Xtras CudaX

How are they getting an extra hour of runtime out of the same Batts?

190min at 150fpm vs 123min at 150fpm for the BT

There is a reduction in power consumption when the engine has to work less hard due to heat and other factors. If you look back at Tahoe, it took 325w to get the Sierra to pull a tech diver at 150fpm, but only 250w for the Cuda to do the same. Only real difference being the much more powerful motor in the Cuda.

The 4-blade prop is also going to generate more thrust than the 3-blade prop at the same RPM so to get to 150fpm the motor will be turning at a lower RPM and since speedower consumption is exponential that would explain the rest of it.

The power tool batteries are an improvement over a proprietary battery like in the Suex that's for sure. But not as nice as the warp core in the Genesis.

DiveX has never really been a contender in the "long range 15hour cave dive dpv" market and I'm not sure this new offering will be accepted there either - despite the giant battery.

It's not a "Giant" battery though, it's a "standard" ~1kwh battery per all of the big boy DPV's over the last decade or so. The "Giant" batteries are held by the Genesis 2.2 @ 1700wh, Bonex Discovery @2300wh, and Seacraft Ghost with 1500wh or 2000wh.

They haven't really been a part of cave diving because they have never really cared about the cave market in Florida as shown by their general lack of dealers, but their trigger also liked to jam on the Cuda though it looks like the new design fixes that problem.

900-1000wh is still nearly the biggest DiveX has ever offered.

certainly is with the exception of the Fury 1150 though that's still in the same size range as the other 1kwh units.

Probably important to lay this out.
UV-18/Gavin Short ~400wh
UV-26- ~600wh
UV-42/Gavin Long ~1000wh

Those were the old "standards" in terms of size so anything within that 800-1200wh range is definitely considered "big" but I wouldn't use "Giant" when we have dpv's approaching 2kwh out there, but even for long range cave exploration the 1kwh units are perfectly fine with one of the paradigms being "1-in, 1-out, 1-reserve" with the "giants" being used for the giant in/out and a towed spare. Either of those are conservatively good for ~15k of penetration which is much farther than I ever intend on going. 8-10k is about the end of my comfort zone.

My perspective as a BlackTip owner:

The PTB setup was appealing to me for the prospect of being able to swap batteries between dives. I.e. on the same day. But, if a scooter has enough battery onboard to last all day, then my priorities are totally different.

Then, I want to be able to charge them overnight, without opening the scooter. And in that case, I would rather use the internal space of the scooter more efficiently than is done with PTBs.

In other words, the Black tip is just fine with PTBs. I would potentially carry a second pair of batteries and swap during a day’s diving.

But, for a scooter with the battery capacity of something like the Genesis 2.1, then, well, the Genesis is just what I would want. It has enough battery that I know I will not use it all in one day. At least, not for me, in my foreseeable future.

Personally, I really cannot imagine spending $7600 on a Cuda X with batteries and a charger over the same money for a Genesis 2.1 that has something like 50% more range at normal cruising speed.

Ludicrous mode sounds fun - for the minute or two that it lasts - but it appears that the Cuda X max sustained speed is basically the same as what the Genesis offers. So, while Ludicrous mode may be fun, it has zero actual dollar value, to me.

Not to mention that I really don’t care for the BlackTip trigger and would much rather have a trigger like the Genesis has. That does have some actual dollar value, to me.

Also not to mention that I have almost gotten blown off out into the shipping channel when diving the Jodrey with my BlackTip. That is thanks to a combo of having to open it every time to charge it and, apparently, getting a little bit of water inside at some point that eventually created a little corrosion on one of the PTB sockets, along with the BlackTip design’s sensitivity to battery packs being out of balance with each other and just shutting off.

After that experience, having a built-in battery pack and through-the-hull charging became a lot more appealing to me.

I did watch the Live and I was pretty excited about the Cuda X when I was thinking it could possibly be priced around $4k… At $7K, and already having batteries and a charger, it is still a total non-starter next to the Genesis.

Yeah, so much this..
Although I haven’t owned the bt tech for too long, I have a friend who just got his genesis 2.1..and wow.
Not really worth it for me, but if the cuda x world be closer around 4K then it could be worth getting in a year or two. For 7k.. not a chance compared to the genesis

First saw it a few weeks ago... and got banned from the FB groups too lol


It is not quiet... it has a different high pitch, very different. I knew when it was in the water, but I rarely saw it during the dive, compared to the other DPVs in the water that day, where I heard those and saw them.

Original was clear anodizing.... blinded everyone first time in the water (HID/LED lights)... dumb idea.

Was going to be called the Tarpon (hence the clear anodizing).




I'll pass, and give John my money for a real product that won't be vaporwear in 2-3 years, and countless revisions (how many tail versions of the Piranas are there? How many versions of noses on the Black Tips, how many versions of Tech tubes?) How ready is it for future sizes of batteries... they claimed the Blacktip would be comparable with newer larger batteries.... complete made up BS.

No batteries for the Cuda or Sierra, those cells haven't been manufactured in over a decade, so you have to go third party.... the batteries even ran out of production and stock during it's hay day! Talk about proper support.

15ah batteries will fit in the blacktip; buoyancy / trim isn’t perfect but it’s way better than the travel with 12ah and I’m not out of tricks just yet.

My piranha was pre PTB and they don’t make a replacement pack anymore. I was told to buy a PTB slice and 4 Dewalts, that definitely rubs me the wrong way.
