    Free Sentry Dpv Dashboard Offer!!!

With a known capacity used (watt-hours) and % charge (voltage), it's possible to calculate a reasonable estimate of the full capacity, if you know what voltage relates to what percent of charge, which the battery...

    Free Sentry Dpv Dashboard Offer!!!

    The Wattsup will display Wh , but on the Eagletree, you need to export the Ah and volts to Excel and integrate over time. A bit of a pain.

    Free Sentry Dpv Dashboard Offer!!!

    There's some of the confusion explained, the Sentry gives you what the Eagle tree does not, Watt-hours consumed, which is the actual quantity of power used. It is voltage, current and time all summed up in one value, so you don't need to keep track of those individual values either mentally or...

    Yes, well I'm an engineer, not a marketing pro. My comment was focused on your statement that you have a workable solution that fits your budget and perceived value. Exactly, and the Sentry eliminates the need to collect that data with a data recorder on previous dive to be used for planning...

    Is It Boring Being The Only One On A Dive With A Dpv?

    It depends on how you plan to dive, as diving with a DPV is completely different than swimming. If you are the only one on the boat with a DPV, you have to make sure the operator is OK with you diving solo, as there is not much point to trying to stay with a buddy that is swimming, unless you...

    Flying with a DPV

    I've never been asked to see a DPV cert to dive off any company's boat, but many dive ops require you to stay with the DM, which kind defeats the purpose of the scooter. The dive ops that do allow them, will require you have a buddy with a scooter also. Call or email the local dive ops before...

    Flying with a DPV

    Some scooters are noisier than other, especially if they use a gear reducer. so that is something to consider, but scaring off the fish really depends on the fish and how you drive the scooter. Some fish become curious and follow along side just to see what you are. Dolphins, sea lions and...

    Announcing new line of SubGravity DPVs engineered by Bonex!

    Randy, I apologize for stepping in on your thread, but as one of the "apples" you are comparing to, the claims regarding lightweight materials and efficiency were misleading. Also in poor taste are "Liking" and "Thanking" of your own promotional posts by yourself and sons, who are also part of...

    Best Underwater Scooter

    Some of the cave divers down in Florida got silt trapped in the pocket behind the trigger and didn't know how to clear it, so I changed the handle design to avoid that. The new trigger is open on the bottom, has plenty of clearance for sand and silt to get out and is a bypass design to sweep...
