the ducer does not have to be all the way under the ice to have full coverage
a 20deg transducer with 2 ft of ice in a 10 hole, the signal only covers 8" of the hole where the ice ends
so in most cases I have the ducer about 16" below the foam..... and it does the trick just fine
well it was a free one
I thought a couple of the fights were action packed
but I agree I think it's getting watered down..too many fights
hey it's just like the NHL......
I think you need a new battery
or
the alternator is not working right
with mine the battery can be dead, I get a boost and 5 minute drive and the battery is charged enough to start the motor
you say you have 2 batteries
I will assume your trolling motor is 12 volts
charge up the starting battery then hook it up to your trolling motor, then let the motor run at full speed and see how long it runs, should be hours if it lasts a long time it's not the battery... it's the alternator
that is if it's not a short somewhere when the key is on..but one check at a time..see what happens
I have 2 gas augers and a hand auger that I can switch back and forth from hand to drill in about 20 seconds and the adapter was made for me and I am going to give it a try, then I can say whether or not it works..... it's for perch fishing early season
an I have an real good battery drill to try with not a CTC piece of crap
