Those of us who spend time anchoring in murkier waters than most places in the Caribbean often have this question nagging us: How well is the anchor really set? Yeah, you do a back down test but, it is still an unknown. If you are in places like the Exumas where the water clarity and temperature make it easy to check on the anchor it is not an issue. But, in places like the Northeast U.S. where visibility may be ten feet if you are lucky and the water temperature is in the low 60's it can be a problem. That's where this new underwater drone might come in handy. It's called the PowerRay and is primarily marketed toward fishermen who want a little more info on what is exactly underneath their boats. But, I see using it as a way to easily check on the anchor without guessing in less than clear or inviting waters. Since it's a tethered Drone there is less chance it will be lost to Neptune too. There is no price on it yet but, if it's reasonable it could be cheap insurance to have a restful nights sleep when the winds start to pipe up. It could also be very handy to see what ones anchor is fouled on if it does not come easily when trying to lift it. Another use would be to locate an item that went over the side that needs to be found.
