I have yet to hear of anyplace in the Caribbean that you can not use a DPV. Bonaire is great, if you dive the East side from the fish huts at Lac. The channel can be ripping on the way back in and you may not have enough power, and have to pick your way through the reef. There's a deep sand...

You'll want to take most of that lead out for fresh water. Simple math check is that seawater is about 2.5% more dense than freshwater. DPV and compass is about 34lbs, so 34 x .025 = 0.85lbs that needs to come out. Cheers, Jon

Reduced power mode kicks in when battery voltage hits 57.5V (+/-0.5V) For reference, peak voltage is 74V and shut off is 50V. Running at full throttle causes more voltage sag from the battery under load than running at cruise power and as the battery approaches the voltage "knee" of the...

You win a cookie. @Texasguy :That's the first I've heard of the Sentry turning OFF while being used, considering it takes 6 properly timed taps to turn it OFF. If you are making a lot of jerky left and right movements on the handle, or have the DPV clipped of next to you and beating up...

Do not use any silicone lube with plasticizers (that rules out a lot of them) They are bad for the nose connector. It should say NSF 51 and NSF 61 (i.e. Food Safe) .

#1 They will not rub through the hard anodizing. #2 You are the first to mention that, but feel free to round the corners off if it feels better. The lever resistance will decrease a bit after a few dives. #3 The motor controller pulls about 3 watts of quiescent power when the motor is not...

Listing motor efficiency is pointless, as it is not uniform throughout the RPM range and does not tell you anything about the total system efficiency. It's hand waving, so you don't look at the relevant performance. A high efficiency motor spinning a low efficiency propeller through a high...

By "earliest opportunity" we mean, don't go home and leave it in the garage for a month without putting some charge back into it for storage. If you were to run it at continuous full or nearly full power for an entire dive until it cut out (highly unlikely, but some have done it) you would want...

Kydex is actually a lot "harder" on a Shore scale. The reason the clear tubing is so difficult to damage, is that its notch sensitivity is extremely low, but you'd have to have an advanced understanding of polymer failure modes to know how that works. .

No, we do not use cheap vinyl tubing from Home Depot. The clear tubing we use, I've used on inspection ROVs with 1atm internal down to 1400' and 3 ton work class ROVs beyond 6000 meters deep, when pressure compensated. I'm not the least bit worried about it. Just to cut it, we have to use a...

Could you explain how you envision that someone might "snag" a DPV tube, such that it overcomes the hundreds, if not thousands, of pounds of force pushing the body onto the tail? .

A little water in the tube section is not a problem, a lot would short circuit the battery and work its way into the motor section. The Genesis has never had a problem with leaking; that's the point of external recharge. You do a good job cleaning the seals and assembling in a clean...

The tube is clear so that if moisture/humidity gets in the motor section, you can see it condense on the inside of the clear tube and get it fixed, hopefully before it causes any damage. The nose carry strap if simply functional. With the charge connector and vent port on the nose, there's no...

The Compass and magnetic shield are the only options not shown on the website. Yeah, I'm overdue a website refresh.

If you had your compass right next to the Sentry, the battery in the Sentry is most likely the problem. Move your compass forward. I usually run it close to the nose.

It's more like crack addiction. Take one for a test drive, the first hits free! :D

The Genesis 1.0 had different controller enable electronics that were designed to disable the DPV if the plug cover was removed in water, but in reality, seawater was conductive enough for the controller to remain enabled, but not fresh water. Since no one has had a runaway DPV, the decision...

Yes. Out of the water the cover will enable the motor controller (as well as in the water while keeping the pins dry). If you forget the plug cover at home or lose it, no big deal, dive it for the rest of your trip and order a new one when you get home. You can actually enable the motor...

A couple clarifications. The recharge plug on the Genesis is a waterproof connector. The rubber plug cover is to prevent corrosion of the pins in water. If you lose or leave the cover back at the hotel (like I've done) you can still dive the DPV, as the water will make the connection between...

They will be an option, not included with a DPV, as not everyone uses a compass.
