Simrad IDST-810 Thru-Hull Depth/Speed/Temp Transducer, NMEA 2000, 235 kHz, Bluetooth LE, Heel/Trim Sensor

Overview

The Simrad IDST-810 is a thru-hull multi-sensor that reports depth, speed-through-water, water temperature, and boat attitude (heel and trim) over an NMEA 2000 network. Depth is measured at 235 kHz with a working range from 0.5 m (1.6 ft) up to 100 m (330 ft), and speed is updated 5 times per second for a smoother speed-through-water number on your displays.

It installs through a 2 inch (51 mm) hull hole and uses 2 inch-12 threads, with support for hull deadrise up to 22°. Power comes from the NMEA 2000 backbone (9 to 16 VDC, less than 200 mA), and the standard DeviceNet (NMEA 2000) cable length is 6 m (20 ft). Bluetooth Low Energy is built in for setup and calibration from a mobile device, and the unit stores its configuration internally.

Key features

• 5-in-1 data from one thru-hull: depth, speed-through-water, water temperature, heel, and trim
• 235 kHz depth element helps avoid mutual interference with common 50/200 kHz sounders on board
• Depth range: 0.5 m (1.6 ft) to 100 m (330 ft)
• Speed range: 0.3 to 45 knots, with 5X per second speed updates
• Hull deadrise support up to 22° for typical planing and displacement hull mounting areas
• NMEA 2000 powered (9 to 16 VDC) with LEN 3 and less than 200 mA draw
• Bluetooth Low Energy for calibration and configuration from a phone or tablet
• 6 m (20 ft) DeviceNet (NMEA 2000) cable for reaching a nearby backbone tee

Variants

This multi-sensor is offered with different thru-hull housing materials to match common hull builds and corrosion planning.

The sensing functions, NMEA 2000 output, and Bluetooth setup are consistent across the range. The practical difference is the housing material and how it fits into your below-waterline hardware plan, including bonding and any positive-ground considerations on board.

• 000-15735-001: Plastic housing. Suited for fiberglass or metal hulls when you want a non-metal thru-hull at the waterline.
• 000-15736-001: Bronze housing. Commonly used on fiberglass or wood hulls where a traditional bronze thru-hull is preferred and maintained like other bronze fittings below the waterline.

Compatibility and fit

The IDST-810 outputs standard NMEA 2000 data for water depth, speed water reference, distance log, water temperature, and attitude. It will show up on NMEA 2000-capable displays and instrument systems that can read those PGNs. The sensor uses network power (9 to 16 VDC), so plan on a properly powered and terminated backbone rather than a standalone 12 V feed at the sensor.

Physically, the unit uses a 2 inch (51 mm) thru-hull hole and 2 inch-12 threads. Overall body dimensions are about 75 mm (2.94 in) diameter and 125 mm (4.92 in) height, so check for bilge access, deadrise, and clearance for the nut and cable bend radius.

Installation and setup

Like any paddlewheel sensor, placement matters. Look for smooth, clean water flow that stays submerged at speed and sits away from intakes, steps, strakes, prop wash, and other turbulence sources. The insert has an orientation arrow that needs to point forward toward the bow so the paddlewheel and attitude readings line up with the water flow.

Use a marine sealant rated for below the waterline and take the time to seal any exposed core if installing in cored fiberglass. Once installed, Bluetooth setup lets you handle calibrations and offsets without pulling up floorboards to reach the network, but range depends on the mounting location and what is between the sensor and your device.

Use on board

This sensor makes the most sense when you want speed-through-water that updates quickly and you also care about heel and trim data. Sailboats can use the attitude and calibration tools for better speed-through-water numbers on different tacks, and powerboats get a cleaner water-speed signal for cruising and performance checks.

Maintenance and care

In salt water, plan on routine cleaning to keep the paddlewheel spinning freely and the depth face clear of growth. If you apply antifouling near the unit, keep paint out of the paddlewheel channel and off the moving parts so speed readings do not get sluggish. A quick check of the O-rings during haul-outs helps prevent slow leaks and keeps the insert seating properly.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Orders of $100 or more qualify for free shipping when eligible. For orders under $100, shipping costs are calculated at checkout based on destination, package weight, and selected service. International shipping is available for eligible products, and certain items may require additional handling, warehouse transfers, or may ship directly from the manufacturer, which can affect processing time.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
