Plus, they're used in evaluating engines, in a lot of aspects.

Some insurance companies are starting to require the 1 million dollar or more vessels to have an IR electrical survey done. Seems smart to me.

Re: Some Recent Thermal Images from Surveys

On a large complicated boat that would be one huge project. They would have to test every circuit. while it is loaded and every connection in those circuits. Otherwise you could just be looking at a panel with no loads applied. Maybe they just insist on high current circuits be tested?

Re: Some Recent Thermal Images from Surveys

There are relatively inexpensive IR devices which attach to smart phones and such. I doubt they perform like a $20K FLIR, but might be useful for boat troubleshooting. Anyone have experience with these?

I had spoken to one of these insurance companies that wanted to subcontract me for these inspections. I required them to sign my own work agreement for each job contracted. They did not want to, and in fact wanted me to accept complete liability without any protection for myself or my company. So I declined.. quickly and completely. Unbelievable they would even make a B.S. offer like that! Honestly, I get that work on my own. I really do not need the insurance companies.

The phone IR camera are very basic with a low temperature range and low definition quality. Good for some fiberglass, but useless on engines, generators, and high voltage circuits. When high heat is seen in a low temperature range IR camera it will just turn the screen white. So they are really toys for basic fun.

I suspected their quality would not be so great. The ones I looked at were about $300...too much for a toy if not useful for inspecting my own boat.

Re: Some Recent Thermal Images from Surveys

The new version of the FLIR One has 4x the resolution of the original version and the MSX blending is supposed to help enhance resolution of the image.

Looking at the live video on this:



It seems to do pretty well in normal temp ranges. I think max temp on the FLIR one is 250 degrees. If all is well on my engine I don't see about 200 on it so it may still be useful there.

I'm really interested in it for seeing core issues. I think I have a small issue on my cockpit floor and am wondering if the FLIR One would be useful in seeing the relative size of that?

Also wondering if it could be useful for pinpointing leaks above a fiberglass liner in the cabin?

I am trying out the new version of the FLIR One. Pretty cool tool. You take the pictures real time and then use another app later on to add the temp spot points. The attached is a test of my heat exchanger as the engine is warming up.
