Transducer depth?

8 posts in this topic

Howdy All...

Being sort of new to this ICE thing and not being very well equipped I've got a question for ya.

I'm using a depth finder (flasher) out of my boat on a "portable" battery pack. I've rigged a transducer "float" system and it seems to work OK. But how deep should the transducer be in the hole? It has a 19 degree cone, if that makes a difference.

Thanks for any input......Dan

The transducer should be as close to the bottom of the ice as possible. The signal can pass thru ice with little distortion, but any air bubbles that cling to the sides of the hole will not reflect signals. This reduces the cone angle of the transducer, if the ice on the hole sides is smooth and clear it will work fine anywhere in the hole.

Thanks Rob!! That's sort of what I thought. But with the transducer's ability to shoot through clear ice kind of confused me a bit. I'll be out on the lake tomorrow and try what you suggested.

Thanks again......Dan

This may sound like a stupid question to most of you out there, but I don't know the answer so maybe you can help me. How does the thickness of the ice effect how your depth finder reads the depth of the water? When I was out on early ice (4") my vex read 10ft. With the ice over two feet thick, will my vex still read 10ft or will it read closer to 8ft?

It depends on how far down the hole you have the transducer. The depth is given by how long it takes the signal to go from the transducer to the bottm and back up. Ice depth will not affect it but how far down the hole will.

Rob, thanks for the response. However, I don't think I asked my question very clear the first time. When the lake has two feet of ice and I am in the same spot when the lake had 4" of ice, if my transducer is held at the top of the water will it still read 10ft?

No matter how thick the ice is, it won't change the depth your fishing in, unless your fishing on a flowage or river whee the depth can change periodically

    •   Stayed home for the 4th this year, was amazed how quiet the cities seemed to be. "Is everybody up north?"
    •   I sure like the sites your old campground kept open for weekenders. Best spots in the campground if you ask me.    
    • so leech, does your campground have festivities functions for there permy site people? ours had a big fish fry on the fourth with a little parade. they do a golfing event to. i heard they finally got some decent playground equipment for kids. there theory was theres fishing. they used to do a pot luck with a theme german, mexican..bleah blah.....but that required work and planning from the owners. took away from the beer drinking! 
    •   I have noticed that trend at seasonal campgrounds too. 20 some years ago when we started camping seasonal sites used to be full of folks 60+ but now it seems that there are a lot of young families in these sites.    The other trend I noticed is that lot rental prices have gone through the roof since then. 
    •   Well in the 12 years we have been at this campground it went from mostly old folks where if your Walker wheel was squeaking someone would run out with a can of WD-40 to stop the noise! Now a lot of young families with kids. Most of the year it's not to bad, but the Holidays can get a little crazy with the golf carts and beer flowing!   I don't let folks bother me much, I have two young grandsons so their in the mix!
    • I have definitely come to the conclusion that on those big 3 day holiday weekends its way more quiet and peaceful if i stay put at home.................even up north. hey i can have a fire and have cocktails at home too!!!!!!! the weekends to go are weekends prior to and after them big weekends!!!!!!!!!!
    •   Pretty much the same on enforcing some of the rules. The 4th was a Zoo and I'm sure the managers head was spinning trying to keep track of who all the kids running belonged too!
    • well it didnt help our family has a cabin up in itasca county and have had it since 1965. the camper took time away from there. granted the camper was 30 minutes from home the cabin 3 1/2 hours but there is agood city block of woods between us and the neighbor.............and we have noone on the other side. i dont mind a little socoilizing but that peace and quiet is right up my ally.   so leech does your park charge extra for additional company not your immediate family? the campground we were at did, but they didnt enforce it fairly. some were forced some got to slide. oh and there were alot of other issues i got fed up with!!!!!!!
    • No ones making fun leech. Just made a statement. I've never seen one like that before. I've seen the hand ones curved, but not the powered one. Guess it could be like the hand one. I could be wrong. Be interested to see if they sold one like that, or someone put a power head on it. I'll let you take over now.
