Thanks Tim. I've got a pretty good handle on depth, but I add a few million leaves every fall, so it might tell me if I'm getting some accumulated debris in spots.
Plus, I may have a thousand fish or I may not, I'm hoping to get a little more info. My HSB have so far eluded me for two years now, maybe a locator will help, who knows.
Glad you had one that worked. I guess it's been available for several years. It was weird, I looked at a few you tube videos, they were all done overseas. I only looked at four videos though. Nothing was very recent.


12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
