Have just got my Smartcast this week. Went down to the pond this afternoon to check out the sonar.
I was still getting a reading at 100 yards on the standard sonar. Thats yards not feet
It seemed to read depth fairly accuratly at around 5 to 7 feet but as sonar reached shallow water the readings would start to shallow to around 3 feet but then jump back to 5 or 6 feet in anything under 3 feet of water giving inacurate results.
In about 4 feet of water I pulled the sonar over a large object which could be seen rising to about 1 foot under the surface, could have been a shopping trolly. It didnt even show up on the read out.
The problem is you can cast the smartcast into 2 feet of water and it will misslead you into thinking the depth is 5 or 6 feet. Not too impressive, you could end up fishing in 1 foot of water thinking its 5 foot. If the water depth is 10 feet and you find a bar, there is no telling whether this bar is 1 foot or 5 foot deep.
Anyone else find this? or do I have a faulty sonar?
