Hollis H-160 vs Dive xtra Sierra???

[CaptnJack]

After reading more data on either one I would say the sierra is more efficient...if it had the ahs like the n19 then it would be able to run atleast .7 more miles. according to data I found.

heres where i found out all the data. http://www.silent-submersion.com/Produc ... a_V1.1.pdf

Stop using various spun marketing data and look at the vastly more objective 2009 Tahoe test if you want to make a "scientific" decision. The N-19 and Sierra's are both fine scooters, although you accidentally bought a Hollis

The paper in the link refers to the "older" 13ah Sierra batteries vs the "newer 16ah ones. This alone bridges about half the gap in capacity vs the N19.

Then my good man i have no idea, my resources have lied to me. But after reading all the specs on all the scooters so far, i wonder how its pushing 60lbs of torque and a 3 mile range.

aren't we all?

BTW I still can't find any info on the capacity of the Hollis Battery.

i looked on the tbt and found that they retracted all data for the time being to add in another scooter, if you have that or a link to it i would be greatly appreciated.

oh and heres a link to the manual that was posted in 08 according to google, in here on page 14 it shows the specs.

Yes they are adding back the UV-26 because the one they first tested was a UV26 in body only. The motor was from a Mako. Because Rodney has never provided sample scooters because he had zero desire to participate in James' tests. Then bitched and moaned about the results being non-representative.

Hollis has never participated anyway so who cares, its not relevant to the scooter you bought cause it was cheap(er).

The Hollis has the same battery capacity and chemistry as the Sierra X (16Ah, NiMH), just with more weight. For the same diver I would expect similar speed and range as the Sierra. Nothing even close to the Magnus or Cuda.

Hm well looking at the specs provided in that manual it would appear that the Hollis H160 uses a 16aH NiMh battery - just like the Sierra. It claims a top speed of 3mph which is probably achievable with a wetsuit and snorkle.

They claim a burn time at top speed of 1 hr.

Think about it for a minute - why would a scooter with similar hydrodynamic properties and the same battery, prop, and shroud go 20 min longer while (supposedly) providing almost twice as much thrust just because it uses a brushed vs a brushless motor?

What I take away from this is the following: Most companies, not just in diving, inflate the capabilities of their product. We know this as "marketing"

Dive Xtras has ironically sort of become a victim of their own honesty since they rely on objective testing under real world conditions (Tahoe benchmark) to provide their spec numbers. If you look at both companies claims side by side and assume the same fudge factor then the Hollis clearly looks superior. Thing is though, in my experience the X number seem to be spot on in the conditions we dive in which is more that can be said for other manufactures.

BTW the Hollis scoot looks nice, and I'd love to give one a spin to compare, I'm just not buying the numbers hook line and sinker.

I concur, doesnt stop my curiousity though

There's no place in Dash's threads for critical thinking, what are you trying to do here?

It's simple physics. You can explain it with the formula E=MC^2, where E is energy, M is mass, and C is delusion.

...and the "C" being squared seems accurate too.

You are way too young to be using "concur", "agree" is much more suitable for you.

Now come on guys. Maybe it was just beginners luck, but that is a shot worthy of a few points.

Looks like Dash bought them hook, line and by accident

Yeah I mean whoda thunk "buy it now" meant like actually buying it???

[Dashrynn]

I'm sure ill look back on that day and say "best accident that ever happened to me" and no! That's not what she said!
