I am amazed every day with he detail these units provide. I use mine mainly for diving but also do a little fishing. I have converted untold Lowrance diehards when they see the images I can get when looking for structure or schools of fish.

With the smaller screen you will need to keep the SI Range lower. Its kind of like a zoom feature, the wider the range the smaller the targets look. The shorter the range the larger the targets will appear.

Where I can use the 997 at 100', you will need to cut yours down to 50-75'. A good rule of thumb is set the SI Range to 2 to 3 times your depth. If you are fairly shallow, maybe 4 times the depth, but again, your targets will appear smaller.

If you are trying to spot individual sm to med fish, this is going to be the only way. Otherwise you will probably only be able to larger fish or schools and bait balls.

Good Luck,
