<div dir="ltr" data-setdir="false">Brian, the end caps are soft rubber with a metal corrugated sleeve. The idea is to keep the inside of the light the same pressure as the outside when at depth. The water pressure squeezes the rubber witch in turn squeezes the oil inside the light. I actually made a test chamber video of the light yesterday. it will be posted soon, so then it should make sense.</div><div dir="ltr" data-setdir="false">Hank</div><div><br></div>

<div dir="ltr">Cliff, </div><div dir="ltr">Thanks' yes I have a sounder on E3000 that is rated for 1,000 feet. I modified it as per Alan's idea sort of. I epoxied the transducer to a heavy piece of fibreglass to add strength to the bottom of the transducer. I took a transducer apart to see what makes them tick, there is a disk inside potted in hard rubber. The bottom of the disk vibrates so the rubber is very thin under the disk. The idea of the fibreglass sheet is to create a hard layer between the disk and the water. Stay tuned on this idea.</div><div dir="ltr">Hank</div><div><br clear="none"></div>

<div dir="ltr">Great how-to video Hank. Talking about how to build one is one-thing, but seeing a demo is so much better. Can I make a suggestion, adding a parts list in the description area of your video. I know you buy the light bar from Amazon but there are a zillion of them there, which one? What size acrylic tube, where did you source it?</div><div dir="ltr"><br clear="none"></div><div dir="ltr">Jon</div><div dir="ltr"><br clear="none"></div><div><br clear="none"></div>
