Info DPV models and specs

[BoltSnap]

Have you seen the DiverTug scooters? I just started to learn about them today.

Check out the Tek36 Compact. It might possibly be something you would prefer over the Go!.

Never heard about them until you mentioned them. I am looking at them now but I can't find any information on Battery gauge to show much battery juice is left U/W. Do you know if they have it?

I don't know all that much about them, but I have not see anything like that. I assume you manage them like all the older scooters (which also did not have a "fuel gauge").

You can probably use the same watt meter thing that you can use on a Magnus. It goes inside the unit and tracks the actual W-Hr you have run, so you can check it between dives, if you want. But, that would kinda defeat the purpose of having a sealed hull...

Seacraft or Genesis for me.

I'm going to start using my BT again (re-potted almost two years ago) and run it until it dies. I'll send it back to Dive Xtras for them to do what they will.

Because of the infamously grouchy individual at Dive Xtras, I don't foresee myself considering either Cuda model.

I hope they can improve. The BT was a sweethheart deal.

I think the Seacraft Diver Propulsion Craft DPV model or Seacraft DPC can be added to the over 20 mile range.

I wouldn't really put that in the same class as anything already on the list.

I struggle to imagine a scenario where someone wants to purchase a DPV and they are legitimately trying to decide between anything on this list and a DPC.

I will happily provide specifications for the mag and viper when we are finished accurately measuring our output.

One thing we are working on is determining a standard cruse thrust requirement.

In other words we need to determine what a real reasonable cruse speed should be and then determine how manny pounds of pulling force a dpv would have to produce to propell a standard diver at a standard speed on a standard day.

Thease are things we do in our engine shop when we dyno an engine its important to measure everything with the same stick

We are currently in the process of building a test tank with a 2 channel force gauge measuring pulling force and torque and the handel and an onboard data logger.

When you can actually measure watts per pound of pulling force you can actually calculate efficiency.

Any specs to report yet?

I'm already putting miles on my new Viper but it would be cool to see data from a standardized test. Still not seeing any added to the website.

interesting .. om comparing thrust in practical terms when for instance taking a lighter scooter at full power in a group at cruising speed (i.e. a VR-Quantum with around 50 lbs in a group of XJ-S Goldfinders with ~75 lbs) ).

Think speed would be sufficient, runtime as well for a 1 hour dive.

Would the difference in thrust pan out in higher battery use due to catch up at speed changes? And differences in max. speed will mean less flexibility in catching up?
