Transducer goop job question?

Gooped in my transducer 3 days ago and I'm hoping to be bubble free.
A couple questions, 1. what will bubble interference look like on the screen?
                           2. can I test for them (bubbles) at home or should  it be on the water?

Thanks in advance, my fingers are crossed!   Tad

When mine was coming ungooped, and I think had gotten some air pockets under it, it would zip back and forth from the actual depth to 10 times that number, and sometimes show static.  If you've put it in a low spot, it might correct itself if your yak leaks a little like mine does.  That's how I became convinced the donut method was doable - and I've never regretted trying it.  Hope you don't have bubbles, and hope it sticks forever. Don't let the area get too warm, like upside down in hot summer sun - the goop gets softer- that's how you can scrape it off if you need to- use a blow dryer.
  I don't know how you could test it at home, maybe rest the bottom in a tub of water? You'd be better off finding someone with a pool or at least a full ditch!

  Hi Tad, the only way to test it is to take it out and try it.  If you are getting a lot of static or reduced sensitivity, then you probably have bubbles.  If you kept the goop thin and the transducer weighted while it cured you are probably fine.  I had to regoop mine after it came off before fully cured (cold weather) and it works fine.  I let it cure a good 2 weeks the second time.  It works great in the lake and ocean and the temp is only a few degrees off.  I think the secret it to keep it very thin under the transducer to reduce and prevent bubbles.  Maybe we should try it this week if the wind dies down.  Matt
