Cuda 250, looks like a great job. I also have a Hobie and installed a fish finder this week. Unfortunately, I seem to have an electrical ground problem. My yak is a Revolution and the fish finder is a Fish Mark 500 (used my credit card points - free). Anyway, I went fishing Saturday at the Great Bridge Locks and headed South to the Centerville Bridge. I had two large mouth bass as keepers, but had an enjoyable day. The finder worked great for about 30 minutes and then "powered off". I attempted several times to power up, but each time it would go off again in minutes. Any ideas? Will you be at the meeting on Wednesday? Katman (La Vern Phillips 439-6146)
