This is admittedly for those of us who like gadgets in our boat. And I apologize to Bruce and all others if this has been covered already.

Our boat is in a hot marina, so we fret all the time about the status of our zincs. And the company that cleans the bottom of the boat leaves us a little uneasy (too busy to replace the zincs today?).

So, we spent a little bit of money ($42) on Amazon (in stark contrast to the lot of money we normally spend) and picked up a Potensic borescope with wifi that remotely connects to our iPhone (we have zero connection with this company, BTW).

https://www.amazon.com/Endoscope-Potens ... B01NBB7UG5

For those of you with Android phones or those willing to just plug the USB connector into your computer, you can get the same function for half the price. What you get for $42 is an inexpensive endoscope (I know, clench of the cheeks at the thought) that has LED lights and a camera attached to 15 ft. of rigid, but bendable cable. This, in turn, attaches to a rechargeable battery and wifi transmitter so that you can receive your images remotely on your iPhone.

I tried it out today. I taped the led/camera to the end of my boat hook and stretched out the cable. Turned it all on (got it to work with some fussing, but nothing crazy...you have to download an app), and was able to see my zincs on the trim tabs, and on the prop. Harder to get into the rear thruster because of the boat hook angle. One complication: phone in one hand, boat hook in other, both guided by a klutz. Seems like a potential bad ending. Would have been better if two people were involved.

So.....we need new zincs and the fellow doing the bottom cleaning job needs to pay more attention to encrusting bryozoans and crustaceans, especially on the prop and rudder. We are going to need new bottom paint next year. You can even take a picture to prove it (not very high quality, but OK).

We decided this gadget stays on the boat for estimating zinc replacements and the day you bump something and want to know if there is damage without having to either go in the water or haul the boat. On the zinc side, this could pay for itself in a season.

Just another toy for the Tugnuts who clearly like toys (our boats are, in fact, toys as we all know).

Thanks for that idea. At that price I ordered one this evening. I also posted the idea on C-Brats (hope you didn't have a copyright) as it could be useful for a couple of different issues sometimes experienced with those boats.

Chimo!
 
What a great idea. I apparently also keep my tug in a hot marina from the looks of the zincs when we pulled it this past fall, having only been in the water 2.5 months since new zincs were installed. I also plan to (1.) install a galvanic isolator to help protect the boat when I am connected to shore power and (2.) use only the solar panel to maintain the batteries when the boat is not in use so I am not grounded to the dock. This device will help to determine how my plans are working.

Thanks for the info...

Looks like they are cheaper on EBAY with free shipping.
 
Awesome! I just ordered one for myself. I checked eBay and they didn't have the iPhone version (which I need) so this may explain the difference in price. I use Amazon Prime so I get it by 9PM tonight with free shipping 🙂
 
Just checked with my unit and it does work with an iPad. However it has to be the Wifi version.
 
I love this! I have been using an old iPhone with a cracked screen in a waterproof case on the end of a selfie stick to check my zincs. :idea: Turn the video on first then stick it down under and point it the best I can. It works but kind of hit or miss.

I think the endoscope product would work much better! I can see using it for other applications on the boat as well including inspection of lines and hard to get to places.

I have a USB adaptor for my iPhone. I wonder if the less expensive non-WiFi would work with that. What is the name of the iPhone App?
 
The iPhone app is WiFi View. I checked the settings and it doesn't appear to offer a USB option. Of course given the name of the app it's pretty specific to WiFi 🙂
 
Thanks. Guess I'll have to get the wifi version.
