airborne_angler Posted May 10, 2013 Posted May 10, 2013 Found 2 graphs at a yard sale. Picked both of them up with a pair of headphones for $10 One of them looks brand new. Nothing has ever been taken out of the packing and it still has the protective covering on the screen. Eveything appears to be there, transducer, power cable...it is missing the instruction manual(sourced a copy on Ebay) and theres no mount...a generic U shaped bracket for a CB should do the trick.Its an Eagle Magna III. Anyone know anything about this unit...age and such and maybe retail cost. The other one is an Eagle Supra Pro ID.Nothing but the head unit on this one.Seller claims it works... So how did I do on this haul...? Quote
KevO Posted May 10, 2013 Posted May 10, 2013 If they work and you aren't expecting a lot from them you did fine for $10. All they will be able to do compared to today's units is tell you how deep the water is. Quote
airborne_angler Posted May 10, 2013 Author Posted May 10, 2013 I'm in a 12' jon boat so I'm not expecting much. I was using an Eagle Cuda unit until I busted the transducer off when the transducer cable got into the prop on my TM That whole unit was like $80 a replacement transducer is like $70for that unit...umm no thanks... I really don't know how to read these things anyway, I just read the depth and temp, I watch the bottom contourfor any drastic changes. Ill wire it up, if it works and I happen to break the transducer off again for some reason, not a big deal,id only be out a little cash...not a deal breaker anyway you look at it. Quote
gramps50 Posted May 10, 2013 Posted May 10, 2013 Go to Eagle's web site and check the transducer in your $10 unit might just work on your Cuda, worth a try. Quote
Super User Fishing Rhino Posted May 10, 2013 Super User Posted May 10, 2013 They'll tell you more than depth. They'll also tell you bottom composition and transitions between different types of bottom and they will also tell you when you have gone from bare bottom to bottom with vegetation, and vice versa.

airborne_angler Posted May 10, 2013 Author Posted May 10, 2013 Well I've checked Transducers and part numbers as Gramps50 suggested, they don't interchange. However they are the same "skimmer"style and I still have the mount on my TM,so all I gotta do is mount it up and wire it and ill be good to go.Before I do that,ill test the head unit on a battery to ensure it functions.

airborne_angler Posted May 15, 2013 Author Posted May 15, 2013 Tested the head unit on Magna III and it lights up, lcd looks as it should so there's a new graph going on my jon boat this weekend...can't wait to try it out... Quote
backwater4 Posted May 15, 2013 Posted May 15, 2013 They'll do fine. Definitely a score for $10. Quote
Downeaster2010 Posted May 16, 2013 Posted May 16, 2013 I used to work for Lowrance/Eagle when those units were introduced to the market. They were reliable depth finders but lacked a good pixel screen. It would sometimes fade out during sunlit days. Too much sun they could go black. If that happened, just turning them off for awhile and they would cool down and work next time you needed them. All in all they still cost a couple of hundred dollars at that time in the Mid 80's to 90's. They were the forerunners of todays pixel machines. Quote
scrutch Posted May 17, 2013 Posted May 17, 2013 I think you did great! Ten bucks doesn't go very far these days. You got a lot of stuff for a little money. Great job! Quote
HuskyKMA Posted May 20, 2013 Posted May 20, 2013 That Eagle Magna III looks exactly like the Lowrance fish finder my dad has in his boat, purchased in 1997. Quote
