Dan Silveira - avid diver, spearfisherman, kayaker and fisherman has created this "how to video" to show viewers a great way of installing a removable Garmin 441s GPS and fish finder combo unit to their kayak. This system uses a Ram mounting system with The Scotty Fishfinder Mount bracket No.272 that locks into the kayak by using a Scotty Round Flush Deck Mounting Bracket No. 344. 

The unit is powered by a WEST MARINE SeaVolt® 12V AGM Battery (PWC* AGM Battery, 19 Ah, 385 MCA, 6.75"L x 4"W x 6.08"H, 17lb. model # 3782612).I put the battery into an otter case for keeping it dry and secure. I run the power cord though a hole that I drilled on the right side of the box and used a rubber grommet with electrical tape to keep everything dry. The box has pluck and pull foam to keep the battery from moving around in the box. Finally the Garmin transducer is positioned on the left side of the kayak in a foam cradle that I made out of a pool noodle. The foam cradle is secured to the kayak with Marine goop. By adding water inside the cradle, then the transducer the Garmin unit is able to read though the kayak and deliver great depth accuracy and show fish in the water column.

How to Make a Lobster Bag:

Dan Silveira - avid diver, spearfisherman, kayaker and fisherman has created this "how to video" to show viewers a great way of making a streamlined lobster bag suitable for freediving or scuba diving. 

If you are tired of getting hung up on kelp or sick of caring a big bulky bag around, then this bag may be the best solution for you.

Here are the parts to the bag:
1" webbing strip 45" long (for waist sizes 30 - 36) (Use more material if needed)
15" wide by 20" long mesh game bag with draw string. 
1" belt buckle 
2 - 1" nylon webbing keepers
2 - plastic 3/4" washers with 1/4" hole. 
Tools: Lighter and sizers. 
Directions. 
  1. Find center of the 45" long 1" webbing belt and make a hole 5.5" on each side of the center line. The holes should be 11" apart. 
  2. Remove draw string from the mesh bag and cut the top of the bag allowing an entry and exit for both the webbing belt and the bungee. 
  3. Cut a 16" piece of 1/4" bungee and run it through the opening at the top of the bag where the cut was just maid.
  4. Run the Nylon belt through the other opening at the top of the bag where the cut was just made. 
  5. Now both the Nylon and bungee should be close together and the bungee can be inserted (both ends) into the holes on the nylon webbing belt. Add the plastic washers to the ends of the bungee and tie an overhand knot. 
  6. Put the webbing keepers on both ends of the belt apx. 4" down from the end. 
  7. thread the buckle and finally weave the ends of the belt back to the keepers. 
  8. You are finished and ready to catch some lobster.
